Found another (incomplete) thread about this tv, and perhaps the same problem. however it was not solved , so i figured i'd start a new thread about my unit.
I have included pics of the power board and the main board.
Fuse is oK. I checked voltages going from PWB to main board.
Leaving out of the PWB is a harness with 15 pins.
pin 1-3, 8 has 12v going out like it is supposed to.
pins 10,14 have 5v going out like it is supposed to.
The other side of the harness connected to the main board is receiving corresponding voltages that are being sent from pwb.
I ran a diode check on the PWB . (in circuit) D201 and D301/D302
had number readings in both directions . ie not OL.
Maybe that is something to consider.
If i remember correctly seems to be 40v going out of VLED 1,3,4
Standby light and remote sensor area seem to be getting 3.3v coming off the main board.
I do not have the remote at this moment. Physical power button does nothing, wont power on tv, wont kick in standby light. Have not taken main board off to look for cracked solder joints,, on the pwr button or otherwise.
I did cycle through a bunch of toshiba remote possibilities via universal remote phone app.
At first i thought power board, now im thinking main board.
I dont want to get a new main board and have the old power board fry the newly purchased main board. The TV was free to me. and 2 new used boards would run about 100.00, but i would like to try working small to big.
Perhaps someone could chime in here.
Sorry, i only have dropbox hosting.
