Ótimo serviço, realmente esses conversores de tensão ajudam muito mas infelizmente os painéis de LCD estão cada dia piores.

Ive had the similar issues with a hisense tv that was stuck between standby and trying to turn on.. It was the 1118 dc to dc. Its still held up three months after being collected.

Hello Tevz. I wonder why it is not easy to replace the dc to dc regulator chip ? Is it because of the aluminum caps or for other reasons ?

@tevzTVTevatronics 6 ай бұрын

No dc to dc IC available.yes also the aluminun cap.

Hi Tez , ...this means the two sides of ckv signal entry painel are defective? a short kiler in the ckv lines dont solve the problem? and increase or decrease vgh voltage? Thanks for your valuable info. Great video.

Hi we can use the ic regulated 7805? 😊

@tevzTVTevatronics 6 ай бұрын

7805 is a linear regulator, its genarate heat in a high amp load, not like a dc to dc converter.

I'm trying to repair a Seiki se39he02 that has standby but no blue light. No 12v on LVDS output at the connector on the board. This is a single board TV. Is it necessary to get FB from the panel for the TV to turn on? The switching transistor has 12.5v on both gate & source but 0v on drain. There is a transistor next to the switching transistor that is supplying the 12.5v to the gate of the switching transistor. Does this seem right? I expected a much lower voltage on the gate of the switching transistor, am I wrong? I'm suspecting panel is bad, I tested it with a T80s panel tester and it would not turn on.

@tevzTVTevatronics 6 ай бұрын

Could you make sure the tv is turning on? 12.5 volts to the gate and when it's turned on the source is also switch to 12.5 volts.

@electronicrepairservice2020 6 ай бұрын

@@tevzTVTevatronics The TV will not turn on, there is no voltage to the LVDS. The board will only go into standby (red led on - blue when TV on)). The drain on the switching transistor goes directly to the LDVS connector but has 0v, even though there is 12.5v on both the source & gate. I wasn't sure if this particular TV required feedback from the panel to turn on LDVS. I wasn't why sure there wasn't 12v output on the drain since it connects directly to the LVDS connector. Thank you for the reply.
