philips 37pf8404 solarized image (changed as15f already)

[reach7458]

I got here an philips 37pf8404 with a solarized image. image one

First guess its a bad as15f. so I replaced it with another. Same issues
So I replaced it again with a rm5101. Same issues

Problem is that is projecting a solarized image irregularly. When I pull the hdmi cable and put it back all is okay for a undetermined time. It also helps if I change the input from one hdmi port and back.

One thing thats weird and I don't remember if it was the case with the previous tvs I repaired.

When the image is solarized it doesn't affect the menu.
Would it be someting else or would it be another as-15f chip (to solder)

I would guess that the AS15F is not soldered probably,
Allready seen this a couple of times

Yes that could be the case. But I replaced it with a rm5101 after that. Then I would have soldered chips wrong twice

did you inspect the pins with an microscoop ?

Yes I inspected all the pins with a microscope.
I even checked the pins with the corresponding traces.

But does a badly soldered as-15f give a good coloured menu and an bad image

Possible main board fault. If you can get one cheap enough try it.
