TV picture is unstable until the TV warms up. This is taking longer and longer. Picture gets large, small, large, small... Quality is also lacking until it is warmed up. This is a Phillips 60'' Is this...


What model and brand is your television?
Is it a CRT type or DLP?
If picture is getting smaller then larger, and its a crt rear projection television sound like you have bad connections around the Flyback transformer and or horizontal circuits. This usually happens when a connection is made on the circuit board and the picture returns to normal especially during a cold start, but as the television warms up the connections on the board start to seperate and the problem starts occuring or it could be in the reverse process. Unstable at first then when tv gets warm it make better connections. All in all have a technician check the HV section of your deflection board.

Flickering/jumping picture


I HAVE THE SAME PROBLEM. TV WAS FINE UNTIL A FEW MONTHS AGO. OF COURSE ITS OUT OF WARRANTY. FROM WHAT I HAVE READ, AND BEEN TOLD, IT IS THE POWER SUPPLY TO THE UNIT. IT IS DEFECTIVE, OR IT OVERHEATS AND TRIES TO SHUT DOWN. A LAW SUIT IS IN PROGRESS AGAINST WESTINGHOUSE TO RESOLVE THIS MATTER. KINDA REMINDS ME OF THE XBOX 360'S WHEN THEY CAME OUT. ALL YOU CAN DO IS TAKE IT IN FOR SERVICE. OR, YOU CAN KEEP TURNING IT ON AND OFF, LIKE I DO. I HAVE HAD THIS TV ON ALL NIGHT BEFORE WITH NO PROBLEMS. AS SOON AS I START CHANGING STATIONS, OUT IT GOES. GOOD LUCK. WESTINGHOUSE WILL NOT EVEN EMAIL ME. I HAVE TRIED SEVERAL TIMES TO CONTACT THEM. I HAVE HEARD FROM THE LAW FIRM IN CALIFORNIA THAT IS GOING AFTER THEM. GO ONLINE, AND JOIN THE CRUSADE.

Phillips 60 in. rear projection approx. 10 years old


This is a common problem with the older models. The opt chip fails. You can get a repair kit at www.magnavoxhelp.com. After a few months of getting smaller and smaller the audio and video will go out but the power light will remain lit.

check the solder around the area of the vertical IC. solder is either cracked or else cold. Cold solder appears as dull. Resolder anything that isnt shiny.

You have a bad blue LCD in the light engine. Replacement of the light engine is the only fix and it usually will continue to get worse over time
