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

Ok, It's better not to do it anymore, the problem is in the panel itself. There are two options, either this or replacing with a new panel.

Well then leave from 2 to 14 inclusive.

I have.

Thankyou so much for all your help

Try different combinations, where it will be better, and leave it.

To be honest, I think that is the best its going to get.
I have tried reducing from 14, one contact at a time, and it doesnt get any better. Anything from 12 or less looses 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

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?

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

Yes, try.

And what contacts do these points go to.

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

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.

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

Pic as requested

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

Its better than it was, but still not quite there

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

13 pin.

Great thanks, I will try that

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 ��

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

Have tried that, pics attached.
