SEMP TOSHIBA	TV 2092 LAV U16	Vertical open only 3 centimeters	Shorted transistor q430	Replace with bd135	fabiusmax
SEMP TOSHIBA	TV 2092 LAV U16	It didn't work, be careful with changing the transistor q430	It didn't work, it didn't come out of standby, I replaced the Q430, it wasn't original, I thought an RGB driver transistor, tube board would solve the problem.	The vertical kept closing at the bottom after a lot of brainstorming I thought about replacing the q430 with a bd 135 and that's it, here's just a tip so we don't waste too much time on simple things hugs	fabiusmax
SEMP TOSHIBA	TV 2092 LAV U16	It didn't work, be careful with changing the transistor q430	As I said, it didn't work, don't leave standebye		fabiusmax
TOSHIBA	U14	The TV even turned on but for a second then it turned off. And it didn't turn on again. So I turned off the +b on the flayback to check the power supply voltages and then everything was ok. Then I turned it on and it oscillated normally, but when I turned on the +b again it returned with the problem	SOLUTION I replaced the flyback and the solution was that it was shorted. Then also check the transistor x112 and c1815 which are close to the flayback, in mine they were faulty		This email address is being protected from spambots. You need JavaScript enabled to view it.
TOSHIBA	TV2051NAV U18	Chido na power supply imajem instavel	Q862 photo coupler	Replace	ze nunes
TOSHIBA	50PJ98G PB8773	When we turn it on, the red LED lights up, turns green and turns red again and the protection relay arms.	R-g-b board ci stk392-110 faulty	To optimize the breakdown on this TV, just turn off the modules one at a time and see when the relay no longer activates, this way it will be easier to start.
