[size=120] Greetings from Venezuela! It is the first time I post on this forum and I don't know if I'm doing well like that. My problem is that I am learning to repair televisions because I like the electronics industry. I already have some knowledge but I know I am missing too much. I have in this house this TV which makes to turn on when plugged into the mains but does not, the LED is flashing. In the main filter I have 178 vcd, and the secondary one has 77 vcd, in the + b there are also 77 v, the eprom has 5v in leg 8 and also the receiver of the remote control. But the vertical ic (Q301) does not reach voltage. What could be happening? PS I can't get the map of this tv. [/Size]

Good morning friend and countryman you can place what components that chassis of that toshiba source regulator uses, horizontal, vertical, micro, jungle to compare with other toshiba chassis.Otherwise if the TV does not turn on you will not have voltage on the ic vertical.

I already did it, the voltage of + b rose to 118 approx., which I think is a more normal value and the LED stabilized. What does that mean?

It means that you may have the horizontal short or say change it or comment

The one he uses is a D2599 and I have only one D2499. I think they are not the same. I tried the one that took it out and apparently it was good.

Excuse me, I meant that maybe it is short or leaking, it insists

I think the transistor is good according to all the tests I've done.

Placing without soldering the base solder emitter connector q the base does not touch anything and try if the voltage appears you may have to lift all the flaibak secondary

OKAY. IF I DON'T UNDERSTAND EVIL, DO I REMOVE THE LAMP AND SOLEL ONLY THE HORIZONTAL COLLECTOR AND ISSUER?

Already did. It works the same as with the bulb. 119v in the + B.

then you have to have a short in the secondary flaybak you will have to disconnect the secondary and go testing one by one

I tested the flyback on the board. Could it be that I had to take it out?

No You do not have to take it out, you have to go up the stages giving it power if in any one you raise the tension appears you will work at that stage
