I have a Phillips 60" television that doesnt power up properly. Model #9p6040 c102. My initial problem was that the sets picture would be lost at random time intrevals and become a vertical white streak in the center of the set. After turning off the set and letting 1 hour or more pass the set would operate properly for a while then repeat. Sound is not affected. At one point I decided to unplug the set and give the interior of the cabinet a cleaning using light air pressure and a vacumn. Now the sets power indicator led illuminated green as it normally would and a small speaker 'surge' but no normal tv function. Also no screen indicator to enter menu options. Do you have any idea(s) on this type of problem and possible costs. I realize the set is 6 yrs.+. Thank You for your time.

Re: Phillips Magnavox 60" tv
Your first problem sounded like a bad solder connection on the vertical circuitry somewhere on the nprinted circuit board. Now its almost anyones guess, as I dont have a clue what you moved or touched when you attempted to clean out the set. its a job for a pro if you have no TV repair experience.

I had the same issue. The screen would shrink and then expand over and over. After thrity minutes it would correct itself. After a few months of doing this it just broke - no sound and no videe but the power light was still on.
I searched these forums but did not find clear instructions or kits on how to fix it. I gave up and called in a repair tech. He fixed my TV in less than 30 minutes.
To help others I documented the fix and created a repair kit and step by step quide on how to fix the problem. You can find it here. http://www.magnavoxhelp.com

Screen shrinks and expands and wams up after 10-20 minutes and then went out completely? Power light still comes on and remote still works? This is a common problem for this model and is most likely related to a bad chip. A tech will charge you over $300.00 to fix it but you can buy the repair kit including the chip, step by step instructions and repair manuals for under $40.00 if you are willing to do a little soldering. Go to http://www.magnavoxhelp.com/ and enter your model or chasis number and order the kit. This will not fix color problems!
