Hi dear Jestine, thanks for every precious article you frequently send to me
I need a solution for a repeated problem I encounter on a CRT tv that uses China board. That is, every voltage is ok but after flyback I got the 180 volts (RGV) reduced to 111 volts which is the same as I got on the horizontal collector.

I changed the 250v*4.7mf cap, then fly back with the new 1010 and even the horizontal IC, but still the same. Please tell me the possible solutions for the cause that reduces the 180 RGB voltage down to about 111 or 115, which is the same volt as a horizontal pin collector.

Regards
Sisay

HI Sebastion,

Check the button again. If all checked to be good then most probably the EEPROM data could have problem.

Hi Sebastian,

I have Hisense 19" lcd Tv that only the volume Down and Channel down works all the other UP buttons and menu Buttons don't respond. I have check the tack switches they are fine. I suspect the main board (RSAG7.820.1264/roh Ver.D) Any clue where to look.

Thanks

HI Abbey,
Bad power ic, power transformer and shorted corresponding components. Check also shorted diodes in the secondary side.
