Have TV Questions? Ask a TV Technician
I have a toshiba LED tv with a dark screen. The front led stays green all the time, but no sound or picture. I also can't turn the tv off with the remote. I have to unplug it to power it off.
Ok I tried with P803 disconnected and it still doest do anything. The front LED doesn't flash when I press any button on the remote.
ok I found something. SCR1, part number BT169DH, is measuring short from pin 1 to pin 3. The data sheet shows pin 1 being anode and pin 3 being cathode.
I removed the part and it measures fine out of circuit. When measuring from anode to cathode with part removed it still measures short. Since I can't find a schematic it will be hard to diagnose the part. There is a transformer next to it, can they short out?
I found the main board on here, but it is sold out.
Not much I can do but wait until a board is available.
