Please check its G2 (grid) volts, should be approx 600-700 volts dc. In some sets it calls Screen Volt.

No Picture on PDP4294


Normally the sets have seperate power supplies for the input/main logic board and the HV which drives the panal (could be 2 parts on the same board). It sounds like you have a problem with the power board that drives the panal and HV. Check to see if any fuses are blown, if the fuse is blown, you can try replacing it, but if it continues to pop, then the main fets that drive the HV are shot and will need to be replaced.

Dark and red picture


First you can up the screen voltage, by finding the HV transformer. It has Screen and Focus control on it this it the Transformer that is in back of set and has an anode lead going to Picture tube. Come up on the screen control slowly and if the picture brightens with vertical lines then it's too high, The red problem is a small transistor that maybe located on the CRT board. It's probably shorted. There are about 3, each going to the different colors Red, Blue, Green.

Samsung 50" hdtv; picture going dark along a sharply demarcated band on screen


This really shouldn't be the normal life of the lamp inside your TV...plasmas are meant to last at least one full year, up to three depending on how many hours per day they are used (I'm sure you can figure out where on that scale your tv lies). It could be caused by magnetic field interference, most likely from a speaker sitting too close to the tv. The magnetic field that is produced by the speaker refocuses the color on the tv, causing dark spots; they can sometimes appear as red or purple tinted areas as well. Most of today's tv's (especially plasmas) and speakers are set up so as not to do this, however you can never really be positive that it will not happen. If you have speakers near your tv, move them at least a two feet away, but the farther the better. Unfortunately, there is no real fix for this problem unless you take the tv to a professional and see if they can de-magnetize that section of the tv. I hope this helps some...if you don't have speakers near your tv then I apologize for wasting your time! haha, at least you'll know for future reference though. Your best bet anyway is to return the tv back to where you bought it or call the manufacturer; if it's only 6-7 monthes old, it should still be under warranty. Good luck!!
