How can I check if my new bulb is good or bad?

I suspect the B+ voltage on the power supply can't regulate the voltage needed for the lamps to run entirely. The B+ voltage regulator looks like a small black box with a tapered top. This is dangerous to replace so be careful. Once you get a new one installed this will fix the issue you are having.


Hope this helps :)

This is a common issue for DLP TV's the bulbs they have are made to last 2000-4000 life hours for Osram lamps this is the lamp the Mitsubishi usually uses so depending how old the lamp is this could be your problem I found the lamp you need for a good price

U restart the tv,u hear alots of clicking?That mean the Ballast is dead or have problems,that why ur picture lamp not sustaning the picture.Replacing the Ballast might or will sustance the picture.

If you have a voltage meter you can pull the bulb out and check for continuity by placing the probes on the power plugs of the bulb. If you have continuity the bulb should be good, and it may be the lamp ballast.

Put the lamp door back on ..:) then rate me

There is a slight chance that you might have an issue with a defective ballast, I mean 3 lamps in 2 years, it's too much. The best way to go here is replacing the ballast, that might solve the issue.

yes the the lamp you need and the only one that will fit is part# 915p020010. This lamp is the same for a wd52525.

Good Day Cawhite;
You replaced lamp and still get flashing light.
1. TV's 'ballst may be bad.
2. If lamp comes on for 2-3 seconds, the problem will most likely be the caps in the power supply. (to see lamp turn on you have to take off back or front (inner panel).
Hope this was helpful.
Good luck, Big Irish.
