Question about Projection Televisions

Philips Model 7P5441C No Display

Recently, my projection TV (I'm not certain of the model number, as it is not with me), stopped having display after a power-surge from a thunderstorm. I suspected the flyback was at fault, so I replaced it-- Upon trying to power it up with the new flyback, there was still no display (Blinking power-light, those two relay clicks, all that deal), but the new flyback I put in would make a short, sharp squeal/whine for about 1 second, then it'd stop. What is likely the problem? Is it an error on my part in replacing the flyback, that I've made a bad connection-- Or is it something besides the flyback which is causing this problem? Thanks for any help!

If you had only ask before changing flyback, this is problems on the deflection board, mostly all different parts bad from caps to zener diodes, the best bet would have been call PTS 18008447871 and asking for board(Deflection) the one with the flyback on it. Changing out board would have been your best bet.

Tv picture shrinks

This is a common problem on certain models of Philips Magnavox TV sets. The most common symptom is the screen will shrink and expand over and over. After the TV heats up for a while the video will work like normal. After a few weeks or months your TV will eventually stop working and not have video.

I have a 60 '' philips tv model # 60pp9363/h17

I have worked on dozens of the DPTVXXX models recently all with audio but no video. In every set the HVG was the problem. 

If you are not sure how to find/repair/replace the HVG youself goto to get their how to guide. 

 Its an easy do-it-yourself fix. 

Also, if you call in a repair tech - they will almost certainly want to sell you a new LSB board for $500.00+. The LSB board is where the HVG is located. Average cost for a replacement HVG is around 140.00 from vancebaldwin, partstore, etc.
