I got mine off ebay for $96.93 for the bulb only including shipping. Here is the URL:

You will have to take out the lamp from the back, very easy, then open the housing and replace the bulb. Here is a video:

Get a can of compressed air and clean out the screens on the lamp housing...you should do this monthly anyway

I have a Mitsubishi WD-52525 television, purchased in Jan 2004, and have had various issues with the set since purchased. When the set was first purchased, it took three different deliveries to get a set...


Buy a new set - not a Mitsubishi DLP. I've repaired 3 sets at the board level.
Many, many bad capacitors on four boards, 12 hours to repair.
If a tech replaces one board, he is only fixing one of 4 bad boards and the set will soon fail again.

The picture wont come on and the tv shuts off after 10 seconds then the stand by button blinks


the picture tube blew out you need to just replace it mine costs 250 if your tv is newer you might still qualify for free bulb replacement like i did but you have to have your reciept to fax to them so they can ship you your free bulb and then you place the bad bulb in box and return. the button blinks you need a new bulb they are good for 2 1/2 years if you keep it on always and use it for computer monitor like I do. but that is what your problem is.

Hello pravinp,

Since this is a DLP set, The bulb becomes suspect. I would take the bulb out and measure the voltage in the socket from which the bulb was taken to determine if the socket is hot. If it is I would then take a resistance reading of the bulb, the resistance should be at 0 ohms. If your bulb is blown replace it with the exact type. The TV might be shutting down to prevent further damage from occurring

I hope this helps
