Official Toshiba 65HM167 and 57HM167 Owner's thread - Page 93

lets start something like the samsung people did. Here is a Facebook page where we can all discuss our white dot issues.

Thanks to the posts and links and instructions given in this thread, I was able to fix my white dot problem on my 65HM167. I found the DMD chip online for $200 and followed the info given here. About 2 hours later, no more white dots, and I would swear that the whole picture looks better. It wouldn't have taken this long if I didn't start out thinking that I had to take the whole light engine out and wasted time labelling and disconnecting wires that didn't need to be disconnected. I can't imagine what it would have cost to have a repair service come out and replace the light engine since they probably wouldn't just replace the chip. $600 or more, I'm sure.

THANK YOU!

In case anyone is interested, I found the chip here:

Cost was $199.99 with free shipping.

I just had the light engine replaced on my 65HM167 due to the white dot problem. Fortunately it was under an extended warranty.

The paperwork I signed for the extended warranty repair showed a bit over $800 for the repair (parts and labor) plus they billed the warranty company another $75 for an estimate.

My 1st white dot appeared on the last day of my MACK extended warranty period. They took care of the problem with no problem - in full. Great service from them.

$200 in parts, free labor and about 2 hours of my time, not counting time spent researching the repair and hunting for the part, and my TV is like new. Not a bad deal. The repair is probably not for the novice, and I'm by no means an expert, but from my experience building my own computers, I felt comfortable replacing the chip myself. If you take your time and don't rush, this repair is certainly doable by the do-it-yourselfer.

Thanks again,

Andy

Congrats on your chip replacement.

I asked my repair guy and he said that his shop didn't do the chip swap. He said the only time they had done those was on Samsung sets, when the manufacturer was replacing defective chips under a warranty.

He said they had lots of problems with the chip swap due to the focus adjustments that often needed to be done once the chip was swapped. From what I've read, you only run into those if you screw up and mess with the alignment screws when changing out the chip.

In any event, it is good to know that if the problem develops again, without a warranty on hand, that dropping in a chip will fix it.

This thread has been great in providing part numbers, pictures, and instructions.

Sure glad I sprang for the extended warranty on this set. It has more than paid for itself and MACK warranty has been great about paying every penny of the repair costs.

[quote=aydu;20931287]Got my new light engine installed this afternoon. Had numerous white dots from a DMD chip.

Started to get the white dots just before my extended warranty ran out. I had a MACK extended warranty for both the set and the lamp and they have been great dealing with both.

Thanks again for the excellent service MACK provided during my warranty period.

I had purchased both a lamp warranty and a 3 year extended warranty on the set. Unfortunately, I used them both.

Each contact I had with MACK was handled in a friendly and professional manner. Issues were handled in a customer focused manner.

Other than being a customer, I am in no way affiliated with MACK.

Based on my experience, I will be a repeat customer on my next electronic purshase.

So I have the 62" Costco version of this TV, and love it dearly. Even after 3+ years the picture is stunning. Unfortunately we are moving into a new home and this TV simply will not fit in the space. Any opinions on what this TV/stand are worth these days if I were to sell it?
post #2770 of 3106
I have a 57HM167 which started having problems last year. After three years of great performance it blew a bulb. IMO this was no big deal since the dealer told me that the bulb would go out after three years of use. I bought a new bulb and six months later it too went bad. I then bought an OEM bulb and it worked. Later this year I started having white dots appear on the picture. After reading several posts for both the Samsung and Toshiba products it was fairly obvious that I had a DMD chip failure. Not wanting to spend more money on this set, especially since I had already spent upwards of $400 on bulps my wife and I decided that we would just purchase a new TV. I have since given the TV to my brother-in-law. My question is where can I find a replacement chip for this TV? I have looked everywhere and cannot find the part. From my brothers perspective the TV is worth the repair since he is getting the set for free. I would hate to just put the TV on the curb. When it was working it provided a great picture. I anyone can help it would be greatly appreciated.

Thanks
post #2771 of 3106
The chip number is shown a few pages back on in this thread.

People have gotten them from ShopJimmy, E-Bay, and Samsung parts.

The chip itself is a Samsung product that was used in their sets, along with Mitsubishi and Toshiba models of that era. Samsung extended the warranty on their sets. Not so with the other manufacturers.

My advise would be to page back on this thread to find the exact chip number and then Google that number for sources.

The chip itself should be less than $200. Replacement requires nothing more than a screw driver and some patience.

The only "red flag" on the replacement is to identify the three adjustment screws on the light engine and not touch them during the disassembly. Messing with these screws will cause the picture to be out of focus once the replacement is done.

Hope this helps.

A dlp chip is just another name for what the dmd mirror is housed in/on. In other words, you need a new chip, the part # is in the link I pasted above.
post #2774 of 3106
Thanks for the info on dmd mirror and dlp chip. I also had white dot problem with my 4 hr old 57hm 167 toshiba. I found threads on earlier pages about dlp chip replacment and sights to find them at. I pulled my chip out for light engine to check number it was different than replacment part 4719-001997, mine was 1910-6143W, but I damaged the ribbon conection onthe back of the dmd board, so I put it back together to see if it would work again, only the sound came back, with the yellow light blinking, just trying to restart. Sent to modusparts, est. was $292 if they could fix. They said they couldn't get the dmd mirror part from toshiba anymore, and they wouldn't fix the ribbon conection, because they couldn't warrant it. Anyone know if I have to replace the dmd board or can the connection be fixed. I did find a board on e-bay saying that it would work in a 57HM167 but last 4 numbers are diferent than mine, and the rev. number is different, any help would be appreciated
post #2775 of 3106
Have you looked for a replacement light engine instead? The whole thing? Depending on availability it could be cheaper.

If the ribbon connection is messed up, you are pretty much hosed. Those things are very delicate as you found out.
post #2776 of 3106
Just got my light engine back today, it looked like they epoxyed the ribbon connection in, so I put it back in the tv, same thing, just sound nothing else came on, let it go about three restarts. There invoice just said dmd mirror is no longer available. Anyone know if the dlp chip is bad will it affect the rest of the light engine like this, no power to lamp, fan, color wheel whining. Before I took it apart it worked fine except for all the white dots. I did find a new light engine it was $667 plus shipping, but from shop jimmy, a dmd board and dlp chip is about $278 plus shipping, if that 's all I need, any suggestions or Idea's.
post #2777 of 3106
Almost sounds like a bad ballast and/or lamp. Or ribbon cable issue. Hard to say with any accuracey on an internet forum after the fact. But the white dots are definatly a faulty DMD. Who did the light engine 'repair'?

As for the replacement LE you need a used one off eBay or similar.
post #2778 of 3106
modusparts.com,I got that web site couple pages back, do you know what the ribbon connection control's, power to lamp,fan,ballast,or all. The lamp is new, less than 5 hrs old, that's why I wanted to fix the white dot issue with a dlp chip. Do you know, does the ballast fire up first , meaning does it need power first before anything else does.
post #2779 of 3106
The good/bad thing about these sets is that Toshiba put most components in the light engine. Prior versions of Toshiba sets had the ballast available as a separate item for replacement. These versions don't.

Bottom line is that this makes the sets more expensive to replace, but, with fewer parts to replace you have a better chance of getting the issue resolved with a light engine transplant.

My repair guy told me that my 65hm167 had three basic components - the power module, the light engine, and the input module.

I'm surprised that the firm rebuilding the current light engine could not find the DMD chip. I've seen them on E-Bay; ShopJimmy; and Samsung parts, within the last few months. They do seem to have spotty availability, as they probably used a ton of them repairing Samsung sets with the white dot problem.
post #2780 of 3106
before I took the dlp chip out to check the part number it worked fine except white dot issue, but taking it out I damaged the connector that receives the ribbon cable, thats the only thing I did that I can see I damaged. Could that be the problem if it doesn't fire up, already tryed snipping off end of ribbon cable like someone else did couple pages back, didn't help. I found a dmd board on e-bay for a 57HM167 but I think it is a different rev. number so not sure it will work any Idea's
post #2781 of 3106
I'm starting to get the white dot issue as well. I'm thinking I'll at least take a look at new tv's before going the chip replacement route, which I would attempt myself.

Once the white dots start, they multiply pretty quickly. With my set, I'd get another dot or two about every week.

My repair guy replaced the entire light engine in my set, which rectified the problem. It was covered under an extended warranty, so I was ok with this - even though the chip repair would have been much less expensive.

My repair guy said that they only did the chip replacement on Samsung sets of the same vintage as mine. Reason was that Samsung was paying for the repair for their owners, and that was all they would pay for. He admitted that it fixed the problem as well as the light engine replacement.

If you can get a chip, and are somewhat handy with a screwdriver, replacement doesn't look too difficult. Just need to identify and avoid tampering with the 3 adjustment screws.

With the Toshiba sets, you don't even have to completely remove the light engine from the set to make the swap. Just be careful about putting stress on any delicate cables.
post #2783 of 3106
I'm another sad/mad owner of a Toshiba 65HM167 with the white dots from a failing DLP chip. We obtained it new late in 2007 and the first bulb lasted until Jan 2010 under fairly heavy use. Sometime earlier this year the first few white dots appeared, and like others have stated, once they start, they multiply fast. That second bulb lasted until Nov 2011 (this month - blew just before the Pacquiao vs Marquez fight), so I was debating replacing it because of the white dots. Local TV repair shop said it would cost me less to just buy a new TV (with $200-$500 credit for this one, depending on what I get, and they finance, heh).

I went ahead and got the second bulb for $118 from discount-merchant.com, where I got the first one for $163, Toshiba Y67-LMP Replacement 75007091. Their warehouse is in the Otay area of San Diego, just off of the 905 at the last U.S. exit, within driving distance. The bare bulbs came wired with the connector, and it was very easy to swap the bulb housing, being careful not to touch the bulb surface. The new one has a different style fuse in it, and thicker wires, but other than that it looked the same.

I found the replacement DLP chip 4719-001997 at shopjimmy.com, as suggested in another post, for the special price of $215.16 (regular price is $349.95). It was in stock Friday morning, but when I returned from picking up the bulb, it was no longer in stock . I have some electronics experience from the Navy, and build my own PCs, so I was planning on getting this chip and hoping for another 4 years of life from the TV. I signed up to be notified when it's back in stock, but wonder if they will ever carry them again.

Some stats I pulled off the service menu (I've never reset them):
Power On: 12,384 hours
Lamp Low: 5,874 hours
Lamp High: 6,510 hours
Lamp On Times: 5610
Temp1: 40° C
Temp2: 44° C

Don't wait on ShopJimmy. Seriously. Look at other venues such as eBay.
post #2785 of 3106
shop jimmy restocks about ever week, I had to put a new dmd board in my HM167, because I damaged the ribbon connector in the board, and the ribbon cable. thought the connector pulled out [it didn't], the ribbon cable comes out of the connector, but I also bent the ribbon cable, causing on of the traces to break,[no connection]. So I cut the ribbon cable off, stripped the ribbon cable on the top to exposed the traces, cut a piece of a business card off the width of the cable, put the two pieces [ribbon cable and strip of the business card] together, and put it into the connector, fired right up. Just received my dlp chip from shop jimmy installed it, and no more milkyway stars, back to a great picture, with all shipping and parts cost me about $311, but I had to by a dmd board that was $72
post #2786 of 3106
oh, also in that $311 I had a shipping cost of $23 for sending it to a repair shop modusparts.com, that couldn't fix it because they could not get the dmd mirror or dlp chip from toshiba anymore, so don't send it to them. I got that web site a few pages back where someone else sent it there and they fixed it for him, but it may have been a year earlier, not sure. It is worth to fix if you liked your picture before and cheaper than a new tv, just hope it last another 4 years.
post #2787 of 3106
I also found the DMD chip on tvserviceparts.com for $325 and they have 4 in stock. The 4719-001997 requires a $41.67 core/dud deposit. I didn't see anything that I would order currently on eBay. This price is where I start thinking it is not worth it to make the repair, but for $215 I will do it. I'll wait a bit and see if anything else shows up at shopjimmy.com or somewhere else on the web. The black Friday deals are looking good too. Thanks for the information about the ribbon cable. I read other parts of this thread where the ribbon cables were damaged. I've also heard that the chip can be replaced without removing the whole board, but will have to see if/when I crack it open. If I do it, the information will be shared here.

Edit: tvserviceparts.com has this under 4 different part numbers, made by Samsung and Mitsubishi. For 1910-6143W they have 11 in stock with no core/dud deposit, genuine new.
post #2788 of 3106
If you get one from shop jimmy there is A 5% discount coupon, it's SJ514C, I used it couple weeks ago should work for you. You still have to take the dmd board out to get to the chip, my ribbon cable seemed to short to turn it around with the cable still in the connection thats why I pulled it out, good luck and hope you see this thread before you purchase it, sorry I just got back the other day on a holiday vaction.
post #2789 of 3106
I replaced my DMD chip and now instead of a constelation of stars I have lines going up and down and a couple of rows of dots going in a line from side to side. Does anyone know if this is something I did or if it might b a faulty DMD chip?


Update!! My wife came home and said I was messin with her about it not wkn. For some reason within a couple of hrs of setting there. She turned it on and the picture is off the hook!! At least for now we r as happy as can b. If u got questions i will help if I can!!
post #2790 of 3106
Put your original DMD back in and see what you get.
