So, I have this Toshiba 40E200U1 that keeps my noggin busy. I don't have the remote for it. Main board is a STC40T / VTV-L32603
Symptom:
It powers on, it runs for 5 to 20 mins, then it turns off by itself. Almost like someone set a timer. All inputs work fine. The main board stops sending PSON to the PSU. After it is off, I can turn it on again and it will run again for like 10 mins or so.
What I did so far:
Unhooked the inverter board = no effect
Reflowed main IC = had no effect
Cooled main IC with heat sink and fan = no effect
Checked the caps on the main board and on the PSU and they are all ok.
Couldn't find any bad solder joints,
Unhooked the IR board =no effect
PSon = 3.5V
ACD = 0.06V ???
DIM = 3.22V
INV = 4.8V
24V = 24.08V
12V = 11.8V
STBY = 5.1V
Is it just me, but I thought the AC detect should be high, something around 5V? However, with the TV off, the ACD is sitting at 0.07V.
I am in a similar boat like this thread: https://www.badcaps.net/forum/showth...0e200u1&page=2
But his ACD was low too, same as mine.
I've monitored PSon, 24V, 12V, etc. All I see is that PSon get's a little blip (something like a 0.02V voltage drop), then its back to normal and 2 seconds later, PSon disappears, so does everything else, besides 5V STBY and ACD. Weird.
