Question about Philips 46PP9302 46" Rear Projection Television
I have a phillips 46pp930217 chassis dtv330. the unit turns on, but there is no picture or sound. the error code i get from the led is 7.
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.
