Pioneer Elite Pro-510 problem - Page 7

I just talked to my tech on phone while he was at home about problem. and evenif I did not tell about problem with power supply board, he said " He is going to order POWER SUPPLY BOARD". Now' that is impressive.................

Hello Guys, as somebody suggested in this thread, I did put small home FAN on back of TV and Problem looks gone When FAn was ON. TV was on more than 12 hrs on saturday and sunday but no blue flash and automatic shut-off. When fan was off, I was getting blue flash and automatic shut off...............

You figure out yourself. Now, Whenever tech changes my power supply board, I will still use FAN to prevent future ELITE problem. FAN was very quite so I could not hear from 13 feet away from my TV.

Can you please post picture of what you did?

First off I would like to thank everyone who has contributed to this Tread. Especially Dave610 for the excellent instructions.

My 510 has been acting up for about 6 months with the same problem most people here have been talking about(The blue flash, power down, and pop) It had gotten so bad last Thursday (going out after being on for 5 minutes, then letting it "cooldown" for 15 minutes) that I decided to call a serviceman to come out and take a look at it. Friday afternoon at 2:30 called and had a serviceman scheduled for Wednesday afternoon. At 2:45, I searched the Web and found this thread. I printed out a number of pages and showed them to my wife. We both felt the same way. I think Gary Miller said it best

" I'm really not willing to spend $500-$1000 repairing a set that was built almost 5 years ago. By the same token, I can't see leaving the set on the curb either. "

On Sunday morning I pulled the cover off the back of the set had my wife watch the screen and touched the different areas of the board with the handle of a screwdriver. This gave me an idea of which connectors and heatsinked IC's to concentrate my soldering to. I carefully pulled the board off and took to a work table to do the work. Initially I just heated each of the solder points up to reflow the solder to make a good connection. After doing that I decided to add some solder to each. I did everyone of the "White" connectors on the top left of the board. I also did all the IC's which Had a Heat Sink. There were also about a dozen others that looked suspect so I did those too. I carefully returned the board and tested it out. I touched the same areas with the handle of the screwdriver and NO flickering/Blue flash. I has been 24 hours without a problem.

So for about $0.50 of solder and $2.00 of electricity the problem looks gone.

Very good explaination

37 Unhappy Elite TV owners...........

I can think of rest of pioneer elite TV owners................

Since technician changed power supply board, TV was on almost 12 hrs, no blue flash or spark. Problem is gone for good.

Thanks guys...........

Now, I can enjoy my elite without any worry..........

in 4 days, My TV was automatically shut-off randomly two times. but no blue flash or spark. I still do not under stand, in front of my eyes, Tech changed power supply board and TV is still doing shuts-off. Thank god there is no more blue flash........................

Jerry, in your post #128 above, from last November, you said that your problems had been solved. No more flashes. Then the next post you make in June says you ordered a power supply board from Pioneer a month and a half ago. Did I miss something? Reading between the lines, does this mean that the problem reappeared on your previously repaired (resoldered) board?

I'm a new addition to the blue flash brightness problem club. My Elite 610 was bought new in late December 2000, not sure of the manufacture date right now. The blue flash/brightness problem first appeared last week, about 4.5 years later. I'm long out of warranty. I found this thread (and another at HT Spot) so am naturally reading everything posted above over the past year+ with interest. In my case, I've never had the power shutting off problem, at least yet.

I'm like a lot who have posted here. Don't want to give up on this set just yet because I really like it otherwise and don't really have the funds to upgrade to a comparable new TV. I need to decide if I can find somebody to do the soldering for a reasonable price, or try it myself (haven't soldered in years and never much or very well then), or break down and just buy the new PS board from Pioneer. So I'm interested to know if the re-soldering jobs aren't lasting very long.

At least I know not to bang my head against the wall with Pioneer...

Thanks for any input or updates.

I had my 510 fixed (soldering the board) two months ago and it's been perfect very since. I don't know how long it will last, but so far so good.

Because I have extended phillips service, I had tech to change board. But other 36 elite owner first tried to solder joint if you want I can upload image of board. It's so easy. When You open back of TV, you see righthand side board where power supply go. Just tap lightly on white connector on toplofty corner on power supply board with screwdriver, You will get Blue Flash/spark.
Anyway, Just solder power supply board. Most of All projection problem due to bad solder joint.

I've started google searching for Soldering Tips and How-to-Solder instructional material. There's some good stuff out there. I'm pretty busy at work right now, but as soon as I get the time I may just get the iron and solder and practice a little to see if I want to give it a go. Thanks.

Since I unplug my TV from outlet about 4 hrs to reset memory, I never had automatic shut-off in three days over 12hr watching TV.

But Just in case I also running FAN befind TV to cool off TV.

Everything runs smooth over week.

Thanks for the reply DJ.

I completely understand how frustrated this has made you. I'd feel the same way in your position. As it is, I haven't spent a dime yet, but I'm not happy with this problem, as it betrays a rather serious shortcoming in design of the "Elite" line. Such a high-end set should not fail on such an issue in a mere 4 years.

But even accepting that such a problem can happen, the response (or lack thereof) by Pioneer is what's most unacceptable. Seeing the posts here and elsewhere it is quite clear that this is a generic problem with the x10 Elite series. Yet, Pioneer does not acknowledge it as such. They should have investigated these problems when reported by multiple owners, concluded that it's a generic design flaw, issued a service bulletin, and offered a complimentary repair to appease their best customers, even though out of warranty. Such an approach would engender some loyalty on my part towards Pioneer, even given the design flaw. How a company responds to issues is much more important than the fact that they arise in the first place.

I'm not in a position to spearhead anything, but I'd be glad to join in any class-action litigation against Pioneer on this issue if somebody were to initiate it. Any lawyers here?

Thanks again to all for posting your experiences on this issue. It's a great help to others like me who now have the problem. At least I can direct my efforts to resolve it more efficiently (and inexpensively).

In my case, I'm seriously considering getting a few items at Radio Shack and trying the re-soldering approach myself first (after a little practice). I figure it can't hurt, as long as I'm careful not to mess anything else up. If that fails I will no doubt just order a new PS board. I don't plan to pay any service techs to touch it, if I can at all help it.

Ironically, the past few days the problem on my set has been happening a lot less frequently. But it still occurs a couple times a night (instead of dozens of times) and I know it's just a matter of time before it's worse again.

Once a tech changed power supply board, after 10 days, MY TV automatically shuts-off every half hour....Just blank screen but green light stays on...... Do you guys know why?

Any suggestion will be appreciated.........

I am with you in lawsuit. We will share everything wahtever comes or go

I'm not surprised by Pioneers lack of response to this problem. I was one of the unlucky ones who bought the 700 5 years ago with the line doubler problem. It was a complete nightmare to try and get any help with this problem between Pioneer and the dealer where I bought the set. I took in a portable DVD player into my dealer to show him the problem and he still looked at me like I was crazy. After months of letters, calls I finally was able to get Pioneer to swap out my 700 with a 710 but at a cost of $1000. This made my investment into the set $9K because of their incompetence. There were many others who can tell you their horror stories with Pioneer with the 700HD.

After 12 days, My TV has blue flase evenif Tech changed power supply board which is brand new. May be defective part................

And Blue Flash was about 30 seconds continous well, I have to open my TV in long week-end and solder power supply board myself..........

I do not understand this thing....TV is going MAD or I am going MAD

EDIT: This week-end I opened my TV again but Tech did not change power supply board. He did change something else..
Anyway, To re-solder power supply board is way to go...

I have used my 510 as my rec room television for watching late night television and movies for the past 5 or 6 years. I was surprised a few weeks ago, when I started to experience the blue flash. Mainly I was surprised because this set is only on for a few hours per day, and I really would not have expected to have problems. I assumed that it was the Blue CRT and the set was on its last legs (not worth any substantial investment to repair given the cost of new units), but I came accross this forum and noted this thread. I will try to execute the repair, and if that doesn't work then try replacing the board. It produces a great picture and I hope I can keep it working for at least a few more years.

Pioneer has had cold solder joint problems that cause shutdown for years, ever since the SDP line of SD units. I have repaired many of them, and almost without exception they always come down to cold solder joints.

"Cold solder joint protocol", as I call it, means going to any solder conn's that have a "halo" around the leg where it meets the pad. One of the worst I ever saw was in a ceiling pj, where the pad was very big - off the flyback - and the halo was enough to almost see thru, a chasm! Very obvious.

This can most easily be seen by holding your flashlight such that you are viewing the solder connection dead on, but with the light hitting it from the side.

Some cold solder joints are invisible to the naked eye, even to a microscope. Only intuition and experience can help you there. They look perfectly good, but can be completely disco'd. Rare, but true.

Then resolder, using good "solder technique". Which means making sure there is enough flux to keep the solder joint gleaming and glossy, refreshing any "dried out" connections. Just touching the joint lightly with your solder will usually lend it enough flux to do the job, without having to add too much solder in the process.

Temperature of your soldering iron tip is important. Keep a sponge handy to wipe your soldering iron tip on, both to clean it and get it gleaming again, and to control the temp, which can easily go into overrun just by sitting there unused. Dragging it across the sponge will cool it to just the right temp when done right.

Look for raised resistors - raised off the board for the purpose of dissipating heat, sometimes with a hole in the board beneath them. To see if they are cold soldered, move them from above the board, and see if the leg moves underneath the board. If so, it is probably a weak joint and should be resoldered. If not, it is tight and secure and probably does not need any further attention.

Anything with a heat sink could cause cold solder joints, just from the expansion and contraction of heat up and cool down. This is especially prevalent in today's convergence ICs, which run ungodly hot in there.

Be very careful of solder bridges, make sure your lighting is very very good. If you unknowingly short 2 legs together by being just a bit sloppy, the results could be devastating to your set. Use a flashlight and view everything you have soldered from several different angles, and if still questionable, from above, THROUGH the board from the top, observing from the bottom where the light shines thru from the top.


Mr Bob

you have a 38th set doing this on this thread now...I purchased my 710 in may 2000..hey the extended warrenty just ended and bam, the blue flash and brightness issue, exactly as the fella's video showed within this thread...So nice to know that I can try and mess with this or buy a new board. Very informative thread, thanks all who participate....
Keith

I just had a tech out to re-solder bad joints on my power supply. He downloaded some "tech tips" from someplace. Thought they might be useful to you folks.

WOW!

Wish I had this kind of resourcing for all my repairs! At first I thought it would all be resoldering cold solder joints, and yes that accounted for many of the repairs. But as I read on I saw that there is a lot more there than just that.

Am saving for future reference.

BTW, swapping EEproms when you need to replace a board is the best way to retain all the work done up to this point on your geometry and convergence. They are the memory ICs, containing all your g & c work. Knowing just where they are on the board is the trick, and hopefully they will not be many-legged SMDs - surface mounted devices - which can be a real pain to unsolder.

Thank you Les!

Tech came today and fixed the power board which was causing the set to shut down. He also ajusted the convergence in the service mode for HD. Years ago when the set was originally calibrated the tech was not able to enter into the service mode for HD because I had an RGB connection rather than component. Today, I switched to component so he could enter the HD service mode. The tech suggested leaving the component input. I had always thought the RGB was the better way. I noticed now I can ajust color levels where you can't on the RGB connection. Opinions as to the best connection for HD, RGB or component. My set is the 610. Thanks

I tried both RGB and components on my HD610 but component was brighter and colorfull. I would stay with component

Djguy, my Pro-710 has begun exhibiting this problem (lightening, then darkening, over and over again) this past week. I got it in 2000, when I was part of the "Pro-700 for Pro-710 trade-in for $1000" group. I'd be interested in being part of such a suit.

I was going to live with the blue flash for awhile,while considering whether to replace the board or attempt to execute the repair. I don't have much experience soldering, so I was somewhat reluctant. However, the set starting shutting off rather frequently, so this weekend I elected to attempt the repair. A few tips for those considering the repair. Many of the connections are extremely small and close together. It is a necessity that you have a wet sponge and an exacto knife in order to be as precise as possible. It is also important when you remove the board to use a screwdriver that has been magnetized as those small screws holding in the board are very small and tough to find when they get away.

I found removal to be tedious, but fairly straight forward. I did not test the board for bad spots with the power on, as I have already had some extremely bad experiences with electricity. I removed the board (power board previously identified as the verticle board on the bottom right of the television), which consists of simply removing all of the connections that plug in and then all of the screws. As I mentioned the screws are very small and fall through the air holes in the frame when you drop them, so be prepared to move the television around and search for a dozen of those little screws.

You have to move all of the harnesses out of the way, and then the board pulls out quite easily. I was extremely careful in transporting the board, given that it has many heavy pieces mounted to it making it pretty flimsy.

I purchased a soldering kit that stated that it was specifically designed for working with small electronics, and I had two exacto knives handy. I also purchased some very thin solder at the hardware store that stated it was designed for use in small electronics. The total cost for all items was nominal. It was very thin, and ideal for re-soldering the joints. It was also very easy to work with, because only a very, very small drop of solder would be produced.

Originally, I was only going to resolder those points corresponding to the connectors, but once I got going -I ended up re-soldering almost the entire board. It took a couple of hours, but once you get a system going it was fairly simple.

I always approached with the solder from the direction that was the opposite of the closest connection. Some of these points are extremely close together and you have to be very careful that the two points don't inadvertantly end up connecected.

As I was going, I used the exacto knife to make sure that there was complete separation of any two close points. Anywhere that looked even remotely too close, I was able to reheat and use the exacto knife to ensure that there were no inadvertant connections.

It took 2 hours or so just to solder all of the points. I originally did not intend to, but there were 2 or 3 different areas that looked suspect , especially those areas around E5 and C204 (someone had previously stated that E3, 202 and 204 were the worst for them-for me it was E5 and 204). Additionally, there were a few other points scattered around the board that looked suspect, so in the end I ended up doing most, if not all of the board.

After it had cooled for awhile, I went back with the iron and the exacto knife to make sure there weren't any areas that might be too close. I feared that I might have touched something when I was working on a subsequent area, or that something might have shifted while it was drying.

I then reassembled the television, and left it on for 48 hours. I have yet to see the blue flash nor have I had the television shut off.

Tremendous success, and I sincerely wish to thank everyone who has contributed to this thread. Not only is the television functioning without the shutoffs and without the blue flash and loss of contrast, but the picture is the best that it has looked in years. I must have had the loss of contrast far longer than I thought, as the picture looks fantastic.

It may sound like a daunting task, but with some patience and precision it can be done. I would love to keep this set working for many more years.
