Re: Hitachi 50HK6100U Screen fault?

It could be a bad panel, maybe something else hard to tell but from the looks I wouldn't be too optimistic, if it's bad panel it's junk, worth very little, maybe just for parts and can be hard to tell what parts may be good, in that condition.

Re: Hitachi 50HK6100U Screen fault?

The price was reduced to £15 so I bought it thinking I can sell the parts if I can't get it working. I removed the right hand side cable from the T-con board and I get a good clean half black and half white screen. If I plug and aerial in I get a slightly polorised picture but no striping. When I removed the left hand side cable from the T-con board and plug the right hand side back in, I get striping and no picture. I tried the tape trick but it didn't work. I tested all the caps on the screen buffer boards but there are no shorts. I tested the T-con board (CCPD-TC495-008 V4.0) and Vcom is 6.8v VGL is -5.8 VGH is 24v and VDD is 15.2v.

Re: Hitachi 50HK6100U Screen fault?

The firmware will not help, the problem is in the panel.

Re: Hitachi 50HK6100U Screen fault?

maybe try tape cut-off method, can check the little mlc caps on panel driver boards for shorts or very low ohms, been over both procedures many many times here.

The right side is not working. Let him turn off the left side and connect the right side and post a photo of the image.

Ukdigger take a high-quality photo of the completely left bar (when viewed from the back of the TV) and the T-con board.

Re: Hitachi 50HK6100U Screen fault?

Pictures with right hand side cable removed, as viewed from the back of the TV. In my original post it should have said left cable removed gives a picture.
The screen changes from one picture to the other every couple of seconds
