Hitachi 48" 42hds69
Alright, my family bought a 42" Hitachi 42hds69 back in Nov. 2008, it worked fine for a few months and then it started having problems with the screen turning off but not the sound, they took it and had the panel replaced i think, or some 500$ part. a month later the problem started happening again, it works perfectly when you turn it on but around 2-3mins later the screen turns off the sound doesnt, the only way to get it to turn back on is to let it sit for awhile but it still randomly turns off, sometimes it will go a few minutes or even all day. could it be the capacitors causing this?

$500 for a part that only last 1 month? Any warranty for the replacement part?

Re: Hitachi 48" 42hds69
That could sound like capacitors but the time frame is too short. Few bad caps are so bad that they go within a few months... twice in a row. Most last at least until the warranty runs out.
With some board pictures we can look for caps and other interesting plasma type stuff. It would help if you can find the receipt that says what was replaced.Comment

nope he gave us a 30 day warranty and it went bad right after it expired, im going to open the tv up later to check the capacitors and ill take some pictures of everything, not sure about the repair receipt thoughComment

He could have replaced the PSU, Ysus or Zsus board. Hopefully he wrote on the receipt what he replaced, because any of those 3 could be failing, though I suspect Ysus or Zsus because the sound stays on, but that's not necessarily the case.
Have you noticed: Does the panel last longer when it's cooler in the house? How about using a fan on the back of the panel? Try cooling the left, center, and right of the panel to see which helps the most.Comment

I don't want to pour salt on the wound, but here in Canada, I can buy a brand new 42 inch 720p name brand (like Samsung, LG, etc) plasma for $600 CDN (or close to $700 with all the taxes).
If you buy from Costco, you get 2 year warranty or you can extend the warranty with a credit card.
Yes, post pics and circle or point out what he changed.

Haven't been able to get it open it has some weird screws, i don't think its the temp cause it worked all day today the top of the tv stayed pretty hot and it just shut off a few minutes ago, sound is still on.. but sometimes i can leave it off for 3 days and it will turn off in just a few minutes.. pretty sure it wasn't the PSU, Ysus or Zsus board my aunt seems to think he replaced the actual screen itself..Comment

so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!!
what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol! 
i had to blow some dust off the board and heatsinks with the datavac as i didnt clean it up before putting it in storage. after finishing... -
Good day ladies and gentleman!
I am currently trying to repair a Grundig Vision 9 37 9880 T USB LCD TV for a friend that has a weird audio problem. Basically everything works fine except for the heavily distorted sound when the Subwoofer module is connected and there is a buzzing sound coming from the PSU PCB.
This seems to be a rather rare TV so there is not much prior on topic help to be found however a service manual is available at the usual sources (Electro Tanya i.e.).
I think the PSU buzzing comes from one of the coils near the bridge rectifier but... -
Hello to the forum.
My name is Christos, I am new to the forum here and i am posting from Greece.
So i have this old German sound card from Marian, called Trace Alpha. To be exact i have 2 of them and i use them professionally for my small FM radio station here. The first one works like a charm, but the second one does not work at all.
To be more specific in the same exact pc with windows 7 (i even tried 32bit) the one works while the other doesn't.
So i tried asking for a schematic from the company and they would not give me one. Instead they... -
Picked up a bahemoth plasma TV not too long ago and just now getting around to looking at it.
No picture but you hear the TV static (white noise) playing loud and clear.
The back was already taken off (and no screws were provided) as the previous owner had already taken a look.
But it seems they didn't get too far and just left it.
When I first took a look I was amazed at how pristine the inside looked.
Its as if the TV had been in a time capsule.
Caps looked like they were just pulled off the self.
Copper coils had no sign of corrosion on... -
