You have a Sony that won't power on and the standby light blinks... Help and suggesti - Page 56

post #1651 of 1759
34XBR2 was 7-blinking this week, wouldn't power up. temps were cold. it had done it a couple times years previously. i got it turned on yesterday however - the room was significantly warmer.
i'll be ordering the replacement ICs & stuff, but in the meantime maybe I'll just leave it turned on 24x7 ... :|

My Sony KV32FS120 seems to be having a problem it will turn on for a split sec then no picture. Sometimes if i cycle thru the inputs it will come back and stay going sometimes not.i get the 5 blink red light something to do with the video.

From what i have read it could be t the ic's on the red,green and blue going bad. where on the board are these and doing the more reading doing the 20 dollar fix has fixed the problem for some people as well. so where to begin? ? The tv isn't HD but is still a nice tv non the less and if it can be fixed fairly cheap i would rather do that then pay to have it hauled away.

It's actually what I think is an older Ikea stand with thin metal legs, I've had to reinforce it to handle the TV. It doesn't really have the room or strength for me to turn it on top of it.

What a great forum. Thanks to everyone who posted information on how to fix the issues with the MC3001DB chips. My Sony Wega failed to where it would no longer turn on and i was first receiving 6 blinks that later changed to 7 blinks. Then I found this forum!

I have never soldered a circuit board before but I'm not afraid to take on a challenge. The posts were very helpful - i don't remember all the names but thanks BobF, Robert, CRTGAMER and others. I read the "repair manual", the Pinball soldering post, and everyones experiences. Armed with that knowledge I acquired everything I needed - including buying one of the Tenma soldering stations from the Pinball guide - I consider it an investment. I practiced my soldering skills on practice sockets a few times before moving on the to actual TV.

Following all of the information here it was easy to step through the proccess to replace the chips. I do have one bit of advice for others attempting this. I have read where many used the desoldering braid to remove the old solder. Using this took me a day and a half of painstaking work to get out the first chip. While the braid was OK in my practice jobs it didnt work well at all on the actual TV board. The old solder needed more heat and the braid seemed to transfer the heat 4-5 inches up the braid to the point that I couldnt hold the braid and it was melting the round plastic holder it is in, and still the existing solder wouldnt melt. Well I struggled through the first chip but then I needed more braid. So while I was in Radio Shack buying more braid I also saw their desoldering iron. 45watts, has a suction bulb, and only $11. Best investment I ever made. I was able to remove the 2nd chip in 10 MINUTES! I did use the braid for some minor clean up around 3 or 4 of the the holes but the desoldering iron was awesome. Radio Shack part# 64-2060.

I saw where another user said they tested the continuity after soldering and I thought that sounded like a good idea, especially to the connected leads. Good thing! I broke out my seldom used digital multimeter and found that on one of the solder joints that had a connection to another lead - I did not have continuity to the other end of that lead. So I resoldered and verified continuity. My repair could have failed I would never have known why.

I did purchase a small set of shears that I saw recommended to cut the legs on the old chips for removal but even with these small shears I couldnt do it. But after checking each leg carefully that it had free movement I had no problem removing it. In fact the 2nd chip basically fell out (again that desoldering iron!)

My Sony is again running great. In fact I think the color even looks richer. I dont know if failing chips can affect the color or not but i swear I have better color saturation.

Again thanks to everyone here. I hope my experience can help those that follow. If you can find this form you can repair the TV.

My KD34XBR960 has the two blink problem and does not stay powered on. The repair schematic suggests transistors Q5003 and Q5030 may be shorted. I replaced both but the problem persists. When I plug it in I hear it degauss, then see the two blinks, a relay click and it turns off then back on. This repeats until the power cable is unplugged.

I tried the hair dryer trick but it did not help. I didn't think it would since It's not the six or seven blink problem. The three blink problem shuts down the AC relay which seems to be happening. Is there a chance that I'm not seeing the three blinks? Could the power be shut off before the third blink is displayed? If I leave the TV plugged in after the first few cycles the second blink becomes shorter to the point it almost looks like one blink.

I also went to Sony's website for service and found two company's that do service for Sony in my area. One was in home and the other was 40 miles away. The in home service company said they no longer service this model. I didn't even call the other place since moving it and transporting it 40 miles, twice, is not very likely for me with a bad back. I called Sony and the representative said the I could call PC Richards since The place I bought it is no longer in business (Circuit City). I called PC Richards and found it was $90 for a home visit and diagnosis plus whatever it costs to fix it, or if I brought it to them it would be $30 for a diagnosis and that would be put towards the repair if I had it done. He then said that parts may not be available. I can imagine since one of the transistors was hard to find.

I love the TV and the cable card feature. But now CRT's and cable cards are a thing of the past. I also hate the cable company's must have tuner box. I'm not exactly sure where to go from here and would prefer not to send it to the landfill, buy a flat panel and have to use the cable box with it.

Any ideas?

update on my KV34XBR910. it now flashes a 2 code, and the image is acting funny. i hate to get rid of it, but i dont think i have it in me to fix it again. if any one wants it they can have it, or help me figure out whats wrong with it.

Well it's gone. A few weeks ago I put it out to the curb with a note describing the problem. The next day someone picked it up. Hope they can fix it. Replaced it with a Samsung UN46ES8000.

Wooooo Hoooo!!!!
Add one more success to the 6-7 blink issue.

My KV-40XBR800 started having issues earlier this week with not turning in. Eventually stopped turning on at all.

I lucked out in finding this, and other similar forums discussing this problem just yesterday.

Picked up the 2 MCZ3001DB's from a local guy, who is actually within walking distance from my home, earlier thus afternoon. After about 1/2 hour of work I had my XBR once again working like a charm.

Thank you to Mark and Bob and everyone else that posted about this problem.

I just wanted to post up and say Thanks to this forum and EclipseDave in particular. I have a KV34-XBR800 that had the 6 blink syndrome. I got the upgraded chips and sockets off Ebay($17 delivered). I got the simple de-solder bulb from Radio Shack($6). I took my Dremel tool with cut off wheel and I opened up post #108 of this thread. By studying the text and photos and working carefully I was able to remove and replace the soldered in ICs with Sockets and pressed in ICs. The TV(which I Love) now functions Beautifully! Total cost, about $23, all in. It only took about 1 hour. 20 minutes to open up the set and cut out the plastic support bar and 40 minutes to R and R the ICs and re assemble the TV. I had some quotes of $300 for this job from "experts". I am somewhat handy, do my own car. bike and boat service/maint., some construction experience. I have done some electrical work, stereo installs in cars. I had soldered some speaker wires and minor Model Railroading wiring. But with the guidance I found on her I was able to do this job! So far, So good. Thanks Again!

Hello, it sure seems like a lot of Sony problems are being solved here! I have done several searches trying to find what a 9 flash code means on a Sony KV-32FS120 with no luck.
It was manufactured March 2006. I loved that heavy old TV! I have a lot of experience soldering but none on a TV.

Any help will be appreciated---DouglasC
post #1662 of 1759
SUCCESS!!

Add one more to the list of successful rookies at TV repair. We have a KV36HS500 and had the 6 to 7 blink standby light code. Found your troubleshooting thread and away I went. I didn't really have much trouble with the repair....probably due the several hours reading up on the subject in this thread. THANKS a million to all who posted here and gave us rookies the confidence to tackle the repair. Fairly funny story about several co-workers suggesting to throw away the TV, but only because they've never experienced a TV with good sound and HD all rolled into one. We have two LED TV's in the house...they do not compare to the "beast". Once again. thanks to all for their help.

I could use some guidance. I'm working on a 34xbr960. It started out giving an increasingly more frequent 7 blink problem. I purchased the replacement chips and sockets and had an electronics tech at work install the sockets for me. Now I have the "3 blinks and no power on problem". I have gone over the board for shorts, retouched the solder joints on the sockets, checked continuity from the pins of the installed chips to the solder joints on the back side of the board and even swapped in the old chips. I found no issues and have had no change in the problem. Any assistance would be grateful. Here are some pics of the solder joints as it sits now:

The solder points all look clean. Did you purchase the revised B model chips?

Double check every connector you removed going to the PCB by unplugging and replugging back in.

Not a good idea putting in the old chips into the sockets which may have widened the connectors due to the old chip legs coated with solder. Make sure any stray solder did not get scraped off inside the sockets.

Try switching the two new chips into the opposite socket, scrutinize the direction of the beveled end.

One trick to make sure you have a solid solder on each pin is to shine a light behind the chip then look at your soldering job. It will reveal if there are gaps in them. Good luck.

Your post is confusing, maybe preview it before posting?

You mentioned a Rear Projection TV, Model number? Did you try replacing the lamp yet?

Hi. I'm in Australia and got the KV-HR36M31 (which is our version of the XBR960 (I think it is) - 36" super fine pitch). Got it new in 2005. Got the 10 blink thing a few days after the 5 year warranty ranout (typical!). Managed to fix it as per the 2 IC process here. The picture was a bit wonky but only showed when viewing soming straight like an EPG, so I wasn't fussed.

Now, although it's still going ok (and I watch a lot of TV), it has a reddish flaring/ghosting to the right of any white part of the picture. Anyone know what that is?

It sounds like the convergence is off. This can be adjusted via the service menu, but before you try that, please write down all service menu settings, or at least take photos of every one. Your television's service menu settings are unique, and if you happen to take one too far and screw it up, you will never be able to get it back to the starting point. Because your tv's settings are unique, nobody will be able to tell you what they are, don't be one of "those guys" who screws up their TV then searches everywhere for default settings that don't exist, document your current settings before trying anything.

Additionally, I should mention that sometimes, bad capacitors or other parts can cause bad convergence, but it is likely easier to try service menu options to focus the red beam before swapping parts inside your TV.

Hello again, I have been re-reading this thread and I still have had no luck finding what the 9 flash code means or even if this set is repairable. Taking up space in the shop so I suppose going to the dump is in it's near future.

Thanks. It's not just a red edge to things but a smear a few inches across. I think I'll take it to a repair shop and if fixable for a reasonable amount get it properly calibrated too.

Why not attempt the power detection chip replacement? Its only around a twenty dollar investment.

SUCCESS! KV-36XBR800 ....six or seven blinks, bwump, click, click and would not turn on. Two MCZ3001DB chips replaced and sockets installed (from B&D on Ebay), and I'm back 100%. I am familiar working with ICs, but I still bent 1 pin when installing one, so be attentive to detail- it's a small place to work in. Thank you very much gentlemen for the powerful information contained herein this topic thread. William Kiser

I have a 34XBR800 that is 2 months shy of 10 years old since I bought it. A few years ago, it died with the standby light problem and I fixed it by replacing a fuse. Last night, it suddenly shut off. I was able to turn it back on, but the picture was very soft, then turned red and shut off again with the Standby light blinking. I turned it back on again, and the same thing happened, but the red screen had horizontal lines and it turned off again. After an hour or so, I tried again and it stayed on for 10-15 minutes before turning off again. I turned it on again, and it stayed on for over an hour with perfect picture again. This morning I was able to turn it on and it worked fine for the 5 minutes before I had to turn it off and run off to work. Is this a sign that the fuse is about to go or the tube about to die, or what?

Edit: This morning it turned off again after being on for only a few minutes. When I turned it back on, there was a red screen again before it turned right off. A 2nd time it turned on ok. Anybody know what these symptoms are?

This morning my 34XBR800 shut off almost as soon as I turned it on. It did it a few more times, usually with a red screen before going off with the Standby light blinking. I was able to get it to stay on after a few tries. Has anyone else experienced the red screen? I'll try re-reading through all 1675 posts for this symptom, but it's going to take a while.

34XBR960n For Sale. Chicagoland area.

I've got a KD34XBR960n that I'm ready to pass on. It has served us well these years, but after losing a brave fight to the 7 Blinks-of-Death I've come to the sad realization that it is time to pull the plug.

Before it heads off to the e-recycler I thought I'd offer it here first. If you need a project, this is it. I'm pretty sure the IC chips have gone bad and need replacing.

If I could get $100 or so in exchange it would soothe the pain of loss.

PM me please.
post #1677 of 1759
Well my 34XBR800 worked fine for another week without symptoms, then one day it shut off, and I had to turn on, and it shut off on me. It did that a few times, then I got it working. It worked for a few more days, then one day the same shut off problems. It works for about a week, then will either have the multiple shut off problem or shut off once or twice and stay on for hours. I noticed some times the white menu screen for my cable box DVR is tinged light blue in areas. Tonight I noticed that and also noticed peoples faces are kind of bluish purple - is one of my RGB guns dying? But wait, after turning it off for a few hours, when I turned it back on later, it was all fine.

I'm giving up on the set and just ordered a plasma replacement. When it arrives sometime in the next 10 days, the Sony CRT will be free for the taking in Denver. PM me if you would like to take it and I'll let you know as soon as its replacement has arrived. Any cash donation would be appreciated, but not required.

My Dad's 36xbr800 starting having the 6-7 blinking light issue. I read this thread and follow the steps and was able to fix the TV!!!! Like some people here I just ended up just installing one of the IC on the D board (IC 8002). My order came with sockets too and just wondering do i need to install this on the board? I just soldering the IC's on the board. Seems like the TV is fine now just confused about the socket. Just want to thank everyone here for their help.....smile.gif

Apologies in advance for not reading through all 56 pages but my KD-34XBR960 is not turning on and the standby light does not blink at all. What gives? Thanks!
