Take good photos of this non-working plank so you can see what's on it.

Try to isolate these pins (CKV...) on the cable with tape.

Re: Hitachi 58HK6100U LED TV - Sound but No Picture

For example, as in the photo.

Have tried that, pics attached.

They glued something wrong, the second photo is about how to glue it, but you need to glue (isolate) these contacts.

Ah I see, I worked from the left, not the right lol

Ill try again ��

Great thanks, I will try that

Re: Hitachi 58HK6100U LED TV - Sound but No Picture

Its better than it was, but still not quite there

Re: Hitachi 58HK6100U LED TV - Sound but No Picture

Here it is necessary to experiment with these contacts, try both 14 and 15, 16, also try to isolate them in turn ...
This microcircuit is responsible for these signals, and you have damaged drivers on the one hand, which must be isolated.

I see, I will try that, thankyou

Take a good quality photo of this chip so that you can read the control points near it.

First you need to isolate these 9 contacts, these contacts go to the bar, you can check with a multimeter where they go (which pins of the connector.

I have tested with multimeter, and have wrote the pin numbers where you have marked on the picture

So do I cover these numbers on cable with tape?

Re: Hitachi 58HK6100U LED TV - Sound but No Picture

Yes, try.

And what contacts do these points go to.

Here are the numbers for the pic you sent

I have covered from 2 to 19, and have picture, although a bit grainy, but no vertcal lines this time

Re: Hitachi 58HK6100U LED TV - Sound but No Picture

Until 19, this is a lot you have glued, from 2 to 9 (inclusive) and up to 14 (inclusive) try
1 does not need to be isolated, this is VGH, you need it.

In general, you need to experiment with these contacts, you can achieve a normal picture if you're lucky.

From 2 to 9 inclusive, lost picture again, white screen with vertical lines

From 2 to 14 inclusive, I get picture, but with aot of thin black horizontal lines, and a weird patch in bottom left corner
