Hi experts! I try to repair my old tv. 47lg70 that lost image when the kids are listening. The screen just goes off but we still got sound. When I close the tv, the standby light are one. If I touch the power button, the led start blinking red then blue. The backlight lit at 100% the dim after 10 sec (inactivity). No image, just sound.
Need advise on 47LG70 lost image but sound
I first try the flashlight test but no image. And I can see the backlight normally working.
So, like I got sound I order an new tcon board (a few mount ago I got a episode with vertical line in dark area) but after swapping the tcon the problem persist.
I order a mainboard on eBay and I receive an broken board and not the correct model. I am waiting for refund...
Before ordering another mainboard for you think is can be the problem? The board is sold out everywhere. I found one on ustvparts.com but I for not know this site. It is a good and trusted site?
Thanks for your help.
