TOSHIBA	U14 U14	The TV only has standby on but it doesn't oscillate and there's no high voltage. I checked that the power supply was low, with approximately 80 volts on the +b of the flayback, I even changed all the transistors on the power supply and up to 432 smd, but nothing increased the voltage on the power supply. +b. I decided to change her computer to the 8813cpng3rp2, then it shot and fell. but the problem was still not completely resolved, it would turn on but the menu would appear on the screen and then turn off.

TOSHIBA	TV 2996	TV doesn't turn on	Good morning everyone, this TV sometimes turned on and sometimes didn't, the power supply went out when turned on, in stand-by it made a certain noise in the speaker, and the on/off relay kept "knocking". I re-soldered the board and checked the cp. 819 and cp. 842 with probably loss of capacity, replaced them and it was just joy. I hope this tip is useful to someone. have a good weekend everyone.		sebastião
