Akai PT50DL24 50 in DLP Rear Projection TV-NO PIC OR SOUND
Hi! I have an Akai PT50DL24 50 in DLP Rear Projection TV, and when I turn the TV on the green bulb lamp just flashes. I replaced the bulb and still occurring. The light flashes for about 3 minutes. I can see the bulb is on but I have no picture or sound.
Check for popped or raised tops on caps in power supply. also try unplugging set for 5 minutes and resetting it. How about does your color wheel spin up? if your color wheel don't startup then your tv will also shut down. also check all fans they all should be running at turn on. if all fails i would say its your light engine.

rear projection tv can be crt or dlp, if crt, try to adjust red color using the customer convergence feature, you will find it in the customer menu usually under advance feature or video settings, some tvs will just give the convergence caption right on the menu listing. If this does not help then the tv might be in need of some convergence circuit repair, probably one of the power outs is damages and needs to be replaced. If it is a dlp if the red shade extends all over the screen or located in a certain area of the screen then i would have the tech check for light engine trouble, this is a common problem on some dlp systems.if i answered your question satisfactorily please leave your positive feed back. thanks
on the main board of the tv there is a fuse located if that is faulty this can happen,there are also many other possibilities but check out the fuse first many a times replacing the fuse solves the problem
as its very negligible to replace the fuse the cost of fuse is under $1.
Is it a CRT or a DLP/LCD projector? If not a CRT, a worn-out projection lamp can cause this symptom. When it is a DLP projector, a faulty Colour Wheel sensor can be the additional problem. If it is a CRT projection unit the High Voltage and deflection circuit must be examined...
