Question about Panasonic PT-50DL54 50" Rear Projection HDTV-Ready Television

1 Answer

Panasonic PT-52DL10 DLP TV

I believe that my TV needs another replacement lamp, however, in addition, there is a loud humming sound coming from the center of the unit behind the main circuit panel. Besides cooling fans, are there other "spinning" components inside? I attempted to disassemble the front panels to investigate the problem, but I am not sure of the procedure to get behind the circuit panel. Please advise.

Thanks,
Bob W.

Picture & color distortion if TV is powered down and then restarted in less than 1/2 hour. If started after 1/2 hour it is OK.

Color wheel bearing can make the noise you describe, and that will also cause color distortions.

Toshiba 62HM195, Loud hum noise when TV is first turned on.


I have the exact TV and had the exact same problems. It is the light engine with color wheel that needs to be replaced, and they are VERY hard to come by for this model. Our repairman has had our TV for 5 months and still cannot locate a vendor that carries the part. He said according to Toshiba, the part has been discontinued. If you happen to find one, please post. I'll do the same.

My DLP TV made a loud popping sound then went off


first. unplug the set for 5 minutes and see if it will reboot. if it does not the you have 2 problems, the chassis is also bad. next open the lamp door cover, it is behind the speaker grill, and behind the lamp door.
take out the lamp and see if it has broken on the inside if it has it needs to be replaced. mits will send you one i believe it is about 100.00 the number is 915P020010. if the lamp looks ok then the color wheel has probably fallen apart.if this is the case the light engine need to be repaired. check out www.tv-techs.com
