XBR 400 Dead! Help! |

Here's my story...
I bought the KV36XBR400 around winter of 2000, and it's been working flawlessly up until maybe 2 months ago.
First symptom was the "sound but no picture"...after a power off and on it would fix itself. This usually happens when I turned the TV off and left on standby overnight.
TV was still working yesterday afternoon. Turn it off to do some cooking, and came back to the dreaded 5 blinks standby. So, I came online to find out what was wrong with my television, which led me to this thread. I was not about to spend $400+ (as many of you guys stated) to repair my television, and risk having it crap out again in the near future. We were ready to trash it and hop on the plasma bandwagon...
Today, as I was searching for a new television, my parents decided to call some local television repair guy they found in the Chinese newspaper and decided to give them a call. The guy was willing to come over today (Sunday), and give us a free estimate. Heck, why not right?
Within 3 hours...he was here taking apart the television. Not sure which board he worked on, but it was on the left side facing the back. He did some readings with a transistor tester I believe, and took him no longer than 5 minutes to figure out that a chip on the board had crapped out. He said it would cost $150 to get it fixed and guaranteed to work for at least 6 months, and he would come back if there was any problem. I guess it was a common issue with the XBR400 because he had a spare chip and was able to start working on it immediately. Not too shabby.
He did some more readings with the transistor tester and started soldering the front and back of the board. Took out a metal L shape piece, replaced the chip, more soldering and he was done. The defective chips reads "SHINDENGEN" "MCZ3001D" "00406". Within 25 minutes the TV was up and running again! Paid the guy 150 bucks, tipped him a few bucks, and a Nestea for a job well done.
Sorry for the long post! Hope this was helpful for you guys!
I'll keep you guys updated if anything happens (knock on wood).

Believe it or not, there are three MCZ3001D chips in the set. One on the A board on the right (IC6001) and two on the D board on the left (IC6501 and IC8002). Its anyone's guess which one he replaced.

Same problem as descibed here, the tech is asking for $500 (didn't even mention D-board), said some about powersupply and two regulators. But warranty the work for 6 months....
what say should I try him?

That's entirely up to you. If a $500 expenditure is no big deal for you, go for it! Personally, I would read through this thread and try some of the ideas mentioned.

You can add me to the list too! My KV-36XBR400 worked fine for the first 2 years, then the week after the warranty ran out it started this intermittant ballooning out crap. At first, it was only about once a week... watching a show ...the picture expands, fades to black...click off. All I had to do was wait a few minutes and turn it back on. I put up with this crap for 4 years until now it won't turn back on. I've tried everything mentioned here and actually got it back on one time. We left it running 3 days until my wife forgot and turned it off one night. Now I can't get it back on again. Responses from the TV repair places have been from "I won't work on those...", to "there's no such thing as a new D-Board, I'll have to send yours off to be re-worked and hope it's OK on the first try". If there is a lawsuit about this, someone please let me in on it. I'm writing my letters to Sony today.

Ditto for me too !
I am going to send my "D" board out to be repaired. I found a company in Indiana that will repair mine for $149 bucks . Before I use the set as a boat anchor I will try this fix first. If this does not solve the problem , I will go to another manufacturer for my next TV purchase .
I can see from all the posts that this known problem with th "D" boards is quite an expensive fix and you may want to try to do the same.

Good luck and let me know how you all do.

Here are details on a successful KV-36XBR400 D-Board repair. Hopefully this will help other XBR400 owners.
My TV began to have power on problems but, initially, I could get it to work by pressing the remote's power on/off button over and over again. When the TV would not turn on, the standby indicator would blink 7 times and stop. This was non-repeating code and, per forum member BUDMAN, did not represent a diagnostic code. Over the span of a couple of weeks the 7 flashes progressed to 6 flashes before settling in at 5 flashes.
The TV became progressively harder to power on and finally it wouldn't not turn on at all.
Before attempting the repair I considered the following options.
- Purchase of a D-Board repair kit from fixyourownTV.com
But I wasn't sure that my D-board was causing the problem. (The repair kit was about $100.)
- Send my D-Board to tristatemodule.com for repair
I seriously considered this option. But, again, I wasn't sure the D-Board was the problem. A D-Board repair would have run about $150 plus shipping both ways. The customer service representative from Tristate suggested that I send in all of the boards to maximize the chances for finding the problem.
- Purchase a replacement D-Board through Sony's exchange program
Again, I wasn't sure the D-Board was the problem and the $243 board replacement cost was pretty steep.
- Pay for local repair by an authorized Sony service center
I never seriously considered this option since the estimated $400 repair cost was more than the cost of a used, but working, replacement of the same exact model.
Finally, I decided to attempt a repair based on other successful repair stories found online and the advice of a Sony repair technician.
The helpful Sony technician told me that KV-36XBR400 "power on" problems often involve one of three MCZ3001D ICs:
IC8002 (D-Board)
IC6501 (D-Board)
IC6001 (A-Board)
These are the same three ICs that forum member jehill mentioned above.
I found the ICs for about $6 each on eBay.
I first replaced IC8002 and that had no effect. Then I replaced IC6501 and the set has been working perfectly for over a month now. (6/1/2009 Update: The TV is still working perfectly well over two years later.)
The IC6501 is also mentioned in a Sony Service bulletin that forum member jehill can send to Premium Members that request it. See the following thread for more information:
http://agoraquest.com/viewtopic.php?topic=26985&forum=34&keyword2=electronics
If the IC6501 replacement did not fix the TV, I had planned to replace IC6001 on the A-Board.
I installed 18 pin sockets in both D-Board locations to make future IC replacements easy. That also eliminates the risk of overheating the ICs during installation. You can find 18 pin sockets for sale online or at local electronics stores such as Fry's Electronics and Radio Shack.
The repair itself was pretty tedious and time-consuming and I wouldn't recommend it to those without some minimal amount of soldering experience. In my case, the hardest part was desoldering and removing the original ICs. I used soldering wick to remove the existing solder.
See the more recent posts in this thread by myself and sholliday<FONT color=#003366> </FONT>for soldering tips and lessons learned.
And there's additional information regarding my repair in this thread:

*** General Caution: Replacing any of the MCZ3001D ICs without any board level diagnostics represents a gamble. Your TV's particular problem could be caused by some other issue. ***

You're welcome and thanks for the positive feedback!
Your post above where you listed the three MCZ3001D locations on the A and D boards was very helpful when I was trying to locate them.

jehill and bobf, you guys rock.
I had to create a profile just to tell you that.
I've got my sony open. Its a kv-32hs500 that died this week.
Well, it started about 2 weeks ago, and I didn't turn it off for 2 weeks. But I lost electricity today, and .... it was over when I got home.
Anyway. I found the D board, and found the circuit locations. For others, if I was above the TV (looking down from heaven I guess), and the screen was at the bottom of my view, and the RF/HDMI inputs were at the top of my view of things..... these circuits would be " right - middle ".
About 3-6 inches from the edge of the board, near a copper wound-y thing.
I'm going to try and tackle the desoldering tomorrow.
GREAT IDEA on the 18 pin socket. That'll keep things simple if it happens again I guess.
Well, this TV is either being fixed by me, or going to the recycle bin. And this forum/posts were the answer.
What did people do before the internet?
PS
You can find the manual (as mentioned) online.
Here are some helpful links at the time of writing.
For those who don't know it, RAR is a program like winzip, but not winzip. Thus you have to get the rar program itself.

Thanks for the positive feedback. I hope that my experience will help others out.
And the internet is an awesome resource. I would not have been able to repair my TV without all the information I found on the internet.

Yes, I did write up some soldering tips but I wanted to clean them up a bit before posting them. I'll see if I can post them in the next day or so..
But, in the meantime, here's an excellent "How-to" link I found:
http://www.pinrepair.com/begin/
This was created to assist pinball machine repairs but the advice applies to any circuit boards. This is very well written and there are numerous illustrations included for clarification.
The information in that link was very helpful to me during my repair effort.
