I've got an SVA lcd tv EV1703, which started off with bad dc board-mounted
connector (for the ac adaptor). Fixed that, now it has problem on the controller.....LED's not lighting. +12V, +5v, 3.3V - all OK.
Does someone have any service data/manual on this unit?
Thanks
Ralf

Hi....you must see the U12 (74F14) ..ok..if this chip is bad the TV no power...easy...when you conect the TV to AC adapter the led will be green and them stay in red.....if you push the power buton and the Tv don't turn on...if probably IC 74F14 (hex inverter) is bad,...ok..replacemente this IC and let me know....

Probably through SVA.. another chineese consumer junktronix wannabe

Don't know if it's any better? Last & only service dealing we had with SVA was nothing short of a nightmare....has to be one of the worst outfits.


Good luck
