I saw some others with the problem..set comes on for a sec. then goes into a protection mode...the light on mine blinks 3 times...


When it first happened I took the back off and (WOW, lol) very dirty, cleaned it out thinking that was the problem...And when I plugged it back in and turned it on it came right on? But, next day same problem. This time I just unplugged it for a few minutes and it came on (keep in mind though, the first time this happened I had tried that, unplugging it..with NO success then).


I guess I am asking if anyone else found out something, like what is the problem???


Thank You for any info.

PS: I have had this TV for about 5 years now and love it. I would hate for this to be a unfixable or cost more then its worth to fix.





I decided to have the name of the thread changed so people can post and read about these kinds of problems with these TVs


I just think we needed a thread for this, as I have read here and other forums of these problems, but they are spread all over the place....

Please feel free to post here with your problem, fix, or answer to another users problem
But please, DO NOT POST HERE your complaint, preference of brand or model, or anything other then what relates to the thread title!!! Thank You



As an added point I like to make.............

Please if anyone has any info on any problem fixes from the standby light blinks (2,3,4,5, etc.. blinks), feel free to add it in this tread.......................


Thank You, have a good day
and good luck with your Sony

3 flashes indicates a failure or caused by "Low +B Overvoltage (OVP) circuit." "IC6505 is faulty. (D Board)" is the probable cause. You can also bring up a self-diagnosis screen to display recent faults. Press display, channel 5, sound volume -, power on. 0 indicates no fault, 1 indicates fault. Press power off on the remote or tv to exit the screen and turn off the tv.

Do you have the service manual for your model TV? I have the service manual for the 970 and can't be sure the part numbers for the D-Board and possible bad IC are the same for the 800. Also be aware that swapping out the D-Board is a complicated procedure. You'll have to mess with the CRT high voltage lead. And then there's the whole issue of restoring all the config data.

OK! Very true and didn't really consider all that...thank you

But my problem still needs to be the "problem ICs" (the ones that have the high failure rate). So back to my question, the MCZ3001D ICs, where can I get them?

OK! sony parts said they have the MCZ3001D(B), they gave the number with the "B" on the end (hoping it is a replacement that doesn't fail as much or at all). As I get it and install, I will keep everyone up to date



Thanks again



PS: cost $22.31 ea. plus tax and shipping.......OFCOURSE LOL

How did you determine that the part you are ordering, IC6501, is the defective part on the D board? As I wrote earlier and it shows up on the 510 and 970 series service manuals, 3 flashes of the standby light indicates failure of IC6505, which is part# SE-140N. The part you are ordering is IC6501.

Sorry WhiteWhiskers

Yes I had said that and I seem to have been wrong. After watching several times it was flashing 7 times. In which case I read else where that the problem part is either IC6501 or IC8002, I don't know which one so I am going to replace both. I am sorry for my confusion there.

Actually I have been sitting here thinking..........

Does anyone know why these ICs keep failing and since they do, is there someway to bypass the faults (well, the ghost faults, since it doesn't seem to be anything actually wrong with the TV, just these ICs that go bad for no apparent reason)???????????

I did a google search for my problem and it found this thread.

Same thing happening with my KV-34XBR800 34". Its about 4 years old. Of course I didn't get the extended warranty because its a Sony, right? My old Trinitron lasted 20 years with no problems.

Anyway 7 flashes on the Standby LED. Sometimes I can get it to come on which sounds like maybe a bad solder joint somewhere.

If I knew exactly which part is bad, I'd just order it and replace it myself. Still trying to search for more info.

As I found in this forums is: 6 or 7 flashes means that either IC8002 or IC6501 is faulty. You can buy them at sony.com/parts . Although it is true I don't know which 1 is bad, but everyone here says they are the problem. cost $23 ea. there is 2 of them (part# MCZ3001DB).

Again I would love to find out if there is a way to bypass the ghost fault, seems it actually isn't a fault, just that the ICs think there is.

....

The KV40XBR800 is a 4:3 format CRT. It's the biggest they ever made and weighs just over 300lbs. Also produces excellent HDTV (1080i) video in its HiDef 16:9 mode (black bars across top & bottom of CRT).

litzdog911- Thank You
that is what I thought.....LOL and I thought mine was heavy


I guess 34" is the biggest 16:9 format?

I'm (sort of) glad to find out my XBR CRT isn't the only one with this "fault mode blinking light". My 32 XBR 400, 32" HD CRT just experienced the failure.


I'm not up to swapping out parts so I want to give it away. It weighs 250lbs but would be worth picking up, for some handy person.


I'm in mid-Michigan, Lansing area. Post questions or PM me.

RCA made a 38" 16:9 tube HDTV, ProScan PS38000. They also made a model with a built-in DirecTV receiver The thing is a monster. Every so often I'll see somebody giving one away (broken).
