Re: Diagnose plz: Sony KDL-46V4000,Tearing or Dark, Sound OK
I could partly fix the TV with some Bumpons and the way described in my previous post.
Partly, because I should have tried this a lot earlier. All the flexing seems to have damaged the connectors too much.
I now could reduce the issues to around 20 percent of switch on's.
Replacing the connectors ( and the LCD) is no option.
key learnings: Fix it before flexing too heavily / often. No rocket science.
thank you PlainBill

The diagnosed problem can be narrowed to the following with high probability:

So my question is now if the bumpons mentioned need to be heat resistent and if the connectors are under high voltage or not!Re: Diagnose plz: Sony KDL-46V4000,Tearing or Dark, Sound OK

Re: Diagnose plz: Sony KDL-46V4000,Tearing or Dark, Sound OK
Hi PlainBill
Thank you for replying. You confirmed our thoughts that the Tcon might be OK.
But as we understand you suggested two possible fixes. The second is the foam, but what is the first one ? Mechanical skills should be no problem.
Also, are there any pictures of the suggested "foam repair" somewhere?
Thank you very much....

Diagnose plz: Sony KDL-46V4000,Tearing or Dark, Sound OK
Hi there.
Our KDL-46V4000 has a picture problem which we would like to fix. But as we are real electronics novices, we need your expertise.
When we turn on the TV the symptoms are:[LIST][*]There is ALWAYS sound[*]Usually there is tearing in the picture on the right side[*]Flexing the TV on the right side leads to either a good picture or dark screen with backlight on[*]If the screen is dark, turning off and on again gives more tries until picture is good.[*]This worked for about 3 months[*]Since recently, the picture stays dark (backlight ok) more often right after...
