This one is for sale locally no sound, no picture, just an amber Vizio light. I think the owner wants too much for it, $100, but after I contacted them they texted back and said that they plugged it back in and it was working. It sounds to me like it could be a PSU issue. What are the chances that it could be something else? I guess there's always the chance that the owner is playing some kind of game.

It's more likely the main board, Vizio power boards tend to be fairly well built -
Re: Vizio P50HDM wasn't working now is. PSU? Possible purchase
If it's a Samsung plasma panel (possibly) it could be cold solder joints, older Samsung plasmas were well known for cold solder joints on the main power transistors.
I'd go for $60, maybe meet them at $75.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Vizio P50HDM wasn't working now is. PSU? Possible purchase
Sorry to bring this back up. The owner decided to keep it since it was working again. This morning the ad popped back up for sale. He now has two of the exact same model with the exact same issue. No power, no sound. Stuck in standby. He wants $100 each plus another $25 each for the stands.
He says both sets were manufactured in '05. Online, a 50" 720p plasma can be had for $500. I don't know what it would take to get these sets working, but I would think that they're lifespans have pretty much ran their course. Am I wrong to think $150 would be about the best I could expect to get for each of them working? They're about an hour and a half away from me so we're looking at about $25 of gas too. If the owner would take $125 for the pair with their stands, do you think there's any good money to be made here?
You still thinking $60 to $75 each?Comment

I wouldn't go for both though.
Also, I am suspicious. Who really has two 50" plasma TVs??Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

I wondered about that too. He said he had the one and liked it so much he talked his naeighbor into buying the same one, the neighbor later moved and sold it to him. I'm sceptical.Comment

Hello,
i have many 5050sff. all of them, and how i experienced over many years for all about 250 DELLs goin through my hands, are fully flashable and can be serviced in any way when the service_mode jumper is set.
Never ever i experienced problems with that.
Now i have one 5050sff machine, where this jumper isnt working at all.
I do not get the normal messge that the jumper is set when booting and a short test with FPT just confirms this. Everything is locked -->> EVEN for reading !?
The history of the machine is that i used it in my office... -
Hi,
I have the above mentioned bord after repair, which was related to a lot of missing smd devices on the back of the board.
There were almost 20 devices missing, caps, resistors and some diodes/mosfets.
The board is generally working now, all PCIe ports are working, Windows installs normally.
However I have a problem with SATA ports 4-7 (the board has 8 SATA ports) - disks are not beeing recognized by the BIOS neither by Windows (which is usually normal in case BIOS does not recognize them).
The SATA 4-7 driver network is quite simple chipset<->buffers/drivers<->SATA... -

Hi i have one Macbook Air 2020 where touch ID is not working (it's not scanning fingerprints). Touch ID was working before, there is no error message during scanning fingerprint it's just not scanning on screen you can see only fingerprint but there are no red updates as when it's working. Power button is working fine.
I've checked boardview and also schematics but i'm not able to find anything related to TouchID ... i have similar issue on a2338 where there was problem with PP3V0_TOUCHID and after replacing UT610 it was working but here i'm not able to find anything related to... -
Hi.
picked up another TV. This time is a Vizio M65-C1. TV does not turn on. I had repaired another 60 inch vizio , Bad main board.
When power button is pressed, the Power led indicator on the bottom right, turns for a few seconds and then it fades away. No backlight or Vizio logo on screen. Removed back cover and repeated test.
This is the TV This TV is a little different from the Samsung I have worked on. Power supply is on the Left side, Main Bd is on the right side, T-CON , not in the picture is on the bottom. I am assuming that the boards in the middle are the LED...
