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.

Sounds like one of two problems
1) Convergence chips are shorted....One quick test is to desolder and remove both STK392 chips....then power the set on. If the tubes light up the chips were shorted. You can get new ones from www.TvRepairKits.com
2) Another possible problem is a bad HVG - AKA the flyback.
Try the convergence chip test first. Note: On some Philips sets you can just unplug cable "1516" instead of removing the chips.
For instructions on how to find/remove cable 1516 visit the website listed above and click on their tips page. On that page click on the "Magnavox DPTV3xxx Checks" link.

I had a similar problem. I had a 52"
RCArear projection tv. It
would do this when I initially turned on the television, but then after a few
"on/off, on/off, on/off" cycles it would stay on. Eventually it
started doing it more; until finally there was a spark and that was it. The tv
was dead.The bloggers called it "the blinking green light of death" (because
of green light on the panel).The
power board is going out.ALSO holding down the Input and Menu buttons afterward will give you
some diagnostic information via 2 sets of blinking indicator lights.
You may very well have issues with capacitors on this set being that it is or very similar to the V26 chassis. Since I have spare test lamps laying around, I would normally try that first. If the lamp still would not stay lit, I would then suspect the electrical chassis (capacitors). When I suspect the chassis, I can usually verify it by pulling it out and partially disassemble it and find blown capacitors
