Question about Samsung DLP HL-P5663W 56" TV

1 Answer

Bightness Change I have a HL-R4667W Samsung DLP TV, and sometimes when we are watching tv the bightness will get less bright. The only way it goes back is if I turn the set off and turn it back on. It doesnt happen all the time, but when it does you can tell it happened.

Re: Bightness Change

It sounds like your lamp is going bad. The lamp part number is listed as "lamp code" on a sticker located on the left side of the set. Use this number to grab a replacement off ebay.

Samsung DLP turns on and off - cycle repeats

make sure put the lamp door back before trying to turn it on because they have switches on them that allow the tv to turn on. If that is ok you probably have a bad ballast.
Call a local tv repair shop to further diagnose the problem.

I have a Samsung DLP 50" TV (HL-R4667W) that has been nothing but trouble. The bulb has to be replaced about every 6 mos or the set turns itself off. I believe there is some other problem other that the...

If the color wheel is the problem you can generally hear a high pitch whine coming from the TV. If it is seized the lamp will ignite for a few seconds and then shut off.

The ballast is only used to ignite the lamp, it shouldn't cause the TV to turn off once it is on.

Since the TV shuts off after it is on I recommend the following:

1st - The lamp cover has a safety switch. if the lamp cover is not pressing on the switch, the TV will turn off after random periods of time.

2nd - The other thing to check is the fan for the Lamp. If the fan is seized or spinning slowly, the lamp will heat up and trip the thermal protection switch. Once that happens the lamp is super hot and could rupture while cooling down.
