Have Protron PLTV-3250 TV and I was told the power supply board was bad. All indications concluded this was the problem. Replaced the power supply board (FSP194-3F01 power supply) and turned the TV on. It has power, but I have no picture. I can hear the sound from each channel, but that is it. I can change the different sources using the remote control and when I come back to TV, the picture (white fuzz or blue screen) will flash for a moment, then it goes black. If I select a source that

No power I have a LG 50PG20 Plasma. It does not have any power. I changed 5 capacitors that were bulging on the power supply board 10v and 50v. I tried to power it on with no results. I looked at all the capacitors on the other boards and they seem to be fine. Is there anything else I can look for that can solve this issue. Thanks


When the caps got real bad they may have taken another part on the power board---also see if any of the foil traces on the bottom of the board were damaged by the caps---some will actually leak a material that can eat the board foil off.Short ... LG Flat Panel Televisions

I have a Hitachi plasma model# 55hdt79 that went black out. No display at all. Sound is ok. We checked the power supply unit and found out that 90v output is missing. We changed the power supply unit assuming that this is the cause, but still the 90v is missing. All the LED lights on in sequence and switch off after loading when I switch on the main power switch. This means no error. The TV can be switch on and off by the remote. Which board is probably the cause of this issue?
