I have picked up this TV, without stand and remote for $20.
It doesn't turn on, it just blinks the green LED as I plug it in.
If I hold Vol+ and Channel- and the I plug it in, after a few seconds, the Input shows up on the screen, just for a second and then the LED stays on.
I have measured the 12V(-12V) and 60V(-60V) and they are there.
I have measured four FET at the top inverter and four on the bottom inverter, on both sides of the TV. There are, six inverters in total, three on one side and two on the other.
There are two more FET looking components, next to the four FETs, but there are no markings on the PCB, so I'm not sure what kind of components are they.
Two pins seem shorted on all four inverters. So basically at each corner of the TV there are six FET looking components. Four of them are marked with Q which are transistors, but the two next to them are not marked. The case of these transistors are horizontal to the PCB and there is a heatsink on top of them soldered to the board, so the transistor markings are not visible and in the SM, there is no schematic for the inverters.
Anybody has experience with these TVs?
Any help would be appreciated.
