Question about Philips 30PF9975 30 in. LCD HDTV
I get a picture for a few minutes then the picture disappears and I am left with only the sound. Then after another few minutes the sound goes also and all I am left with is a blank screen.
blank black screen after fewe minutes or sometimes seconds. Sound ok
is there anyone with a solution. modelnr is 30pf9946
I had this problem on my 42" Philips. Just got it yesterday and worked fine on the tv stand. As soon as I mounted the TV to the wall via wall mount system, I had the exact same issue you did. Figured it out today.
The wall mount was putting pressure against the center of the back of the tv (tv set had a slightly rounded back plate, and the mount was a flat plate). As soon as I put spacers (part of the wall mount hardware set) between the wall mount braket and the tv so there was no contact except at the mounting holes, the tv worked fine.
My theory is the pressure pushed the tv back plate against some board components which caused them to overheat (no air flow); or put pressure on internal connectors. I dont know.
Hope this helps, may not apply to your situation.
