Faults & possible causes to LCD & Plasma screen are given with illustrations. You can get an idea about the fault to an extent.

The set does use a lamp for a light source and average life is 2 years or 2000 hours---many lamps before they actually fail get to be darker.

U have an image screen burn in.This is not fixable.This have happen,because u left the same image or setting on same setting day in day out,tv on all the times.

Your light engine is bad and needs replaced. I have a tip at http://www.fixya.com/support/r4251975-replace_dlp_light_engine which explains the problem, how to fix it and where to get the parts. Let me know if you need more help. Thanks for using FixYa and for the great rating.

I'm assuming you mean the red light or lamp? provided you know the make and model of the TV, you can no doubt find a replacement bulb for it online.

Do a search or contact the manufacturer to see what they can do, but you should be able to do it yourself.

you have a bad panel! contact mits!

Hi

ok you have defective RGB at the CRT board! the suspect is the variable resistor in green section and red section!

Thanks!

Please verify model # from rear of set.PVAT! Look closely at signal PCB for signs of CRT coolant leak.

1. THE SYMPTOM IS BRIGHTER IMAGE ON THE SIDES AND DARKER IN THE MIDDLE. THE PROBLEM CAN BE WITH RED BLUE AND/OR GREEN. CHECK FOR PROPER CONNECTIONS TO THE "DAG COATING AND CONNECTIONS TO PIN 9 ON THE SOCKET OF THE AFFECTED CRT. MAKE SURE THESE GROUND POINTS ARE COMMON WITH CHASSIS GROUND

Sounds like you have two differant problems. A red drive or red picture tube is bad and the conbvergence IC's are bad. To test the red drive disconnect the green picture tube socket BUT MAKE SURE THE SET IS UNPLUGGED!!Then remove the red socket and move over to the green tube. Then turn on the set. If you get the same out of the green then you have a drive problem that needs to be trouble shot for a bad componet. If you do get a picture with the red connected to the green then the red tube is shot. If you know how to read a schematic, get one and then you should have no problem troubleshooting the red drive and the convergence problem. If you dont then there is no easy or quick fix as this is a solid state set and there are no user replaceable parts inside this.,. Your going to need, for safetys sake, call in a trained tech to assist you with this repair
