After you replacing the lamp, you need to check the fan, if it is workinh otherwise it will automatically shut off due to temp rating.

I would suggest replacing the Lamp

Sounds like some debris of some kind is on your blue tube or could possibly need cooling fluid. If you take the back off, you should be able to stick your head in and look into the tube to see if anything is in there. Cleaning lens and mirror could also help.

Thanks for info, its very helpful for those that have similar problem in TV.

You have to close the lamp door. It has a switch in it much like a clothes dryer door in that when it is open it wont operate.

If you herd a pop noise, the lamp would be my suspect. You should be able to take it out and varify. All LCD projections are subject to the same type of failures and without notice. If you have around 3000 or 4000 hrs of use the set would probly give you a message the lamp should be replaced soon.
Hope this helps,

bad lamp, yes it will not have no sound, 

Hi,
Let me know following info...
Color were fine before Lamp replacement?
Make sure replacement lamp is Panasonic original and it is not aftermarket product.
Thanks.

probably short on power or there is a damaged cord in the plug. Do you hear any sound? If so, the LCD of the TV is the problem. Have it fixed if the warranty is still available and not expired.

compressed air ssprayed in he vents usually on the side or top of the screen if that does not work try taking the face plate of yourself if it has clasps to prevent you from opening it dont because if you break those claps it breaches any and all insurance policies you may have on your tv

You will find this very easy. Take the front panel off. It just pops off. Two screws..one on the out side door and one inside the door. You can do it from there. Oh yea put the back of the Tv back together....lmao.

You didn't give much info on the symptom's but you probably have a power supply or main board problem.

first try unplugging it and let it reset, for at least 3 minutesthen try it again

Ok well it's the shop for this bad boy I am afraid.. to me it says Power Supply OR fault that causes PSU to shut down.. either way unless ya a dab hand at this type of thing, its obtain a reputable serviceman and get a "Quote" and proceed from there.. GL
