Question about Philips 60PP9352 60" Rear Projection Television
Can barely see a picture in the background. Screen is covered with horizontal white lines. tried 75Ohm connector, composite, and component connections with same results. Any help is appreciated.
The green dot in the center sounds like a burn mark on one or more of the picture tubes inside the set, and the curved lines are telling me that you have a problem in the convergence circuits. The blue haze around everything white tells me you either have a lot of dust build up on the lens over the CRTs, or your picture tube(s) are very weak. If this set is over about 12 years old, I would replace it. I doubt if you will be able to get the green dot out of the picture without changing the tubes which would be VERY expensive.

This denotes a problem called blooming the horizontal lines you see are called retrace lines this is caused by the increase in anode voltage which could be caused by an increase in HV section current which trips the overcurrent protection dircuit and turns the TV off.If you do not have electronics experience I would suggest taking the set to a TV repair shop.

What you're describing is probably contaminated coolant in the crts. Between the outer part of the crt and the lens is a chamber filled with a coolant (ethyl-glycol) which can become contaminated and cause blurred picture. I'd strongly recommend taking this to a shop the procedure for changing these is a bit beyond the layman level.
Remove Crt assembly. Mark the Crt lens position for accurate reasssembly.
Mark the centering ring's postions to make easier realignment and carefully remove lens assembly by removing the four torx screws. Keep Crt assembly vertical so you won't leak the fluid...
Remove the inner lens by carefully prying up on the edge of it.
Dump out the fluid in the sink and wash the face of the Crt and chamber with water to remove all the fungus and crud. Flush the chamber with isopropyl alcohol to kill all the fungus and dry thoroughly.
Reassemble inner lens and outer lens and tighten all four torx screws.
Remove side filler plug and fill chamber with approved new Crt coolant, reinstall and converge.
Repeat this procedure for the other two Crts. It will need this done whether it looks clear or not !! The green and blue Crts in this unit are prone to this failure.
Hope this helps

Initially, pls try lowering the screen resolution of your PC. This can be done at the Display Properties/Settings tab and then move the slider of the Screen resolution towards the left, Apply OK. In some instances, you need to also lower down the Screen refresh rates in the Monitor tab of the Advanced Properties.
If your concern has not been corrected after completion of the above procedures, then other methods can be considered.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
