First I need to clarify your tv. Your tv is not a DLP. It is a standard 3 CRT rear projection. So there is no Lamp/bulb to replace like you would find in a DLP.
\015\012As for your problem. I would suspect a convergence failure. I believe on this set, there is a small board in the back of the tv above all other boards with two STK chips on it. Access if from the back of the tv. You should be able to unplug this board and see if the tv comes on. If it comes on, the picture will be distorted and colors separated. if this happens, then you know you have a convergence failure.
\015\012If this is the case, you can either:
\015\012 a) have a repair shop fix it
\015\012 b) buy a new or used(most likely) board and replace it yourself and then re-align the tv.
\015\012c) Replace the STK chips on the board, any faulty resistors in the area and possibly a fuse or two.
\015\012You will need the service manual to help you with how to do the re-alignment once the chips are replaced.

I have a Polaroid 2611-TLXB TV that was manufactured in September 2007 and recently, I turned it on one night and there was no screen at all. The blue power light was on though and I could turn it on and off with the remote but still no screen. I tried unplugging it and plugging it back in but nothing changed. I checked the back and there is a red blinking light.

I have the WD-65731 DLP HDTV. The tv will not turn on. Initially, it will power up, and you can here the fan running. The green "timer" light will blink for several seconds. Finally the fan will turn off and the blinking timer light will go out. I have tried resetting the TV, as well as unplugging the power cord and all input cords. After waiting 60 seconds, I reconnected all cables and tried again to turn it on, but the result was the same. No other indicator lights are on during ths process

JVC AV-36D502. Our TV has been on the fritz. Sometimes when we try to turn it on the power light just blinks. We have figured out if we wait a minute we can unplug the TV plug it back in and then the TV will function normally. Although it does take the picture a little longer to come up. Still looks fine though. Any ideas what may be causing this?

My Sharp Aquos LC-60LE847U lcd TV has some kind of controller issues. At times when we turn the set on using the remote, the indicator light will light but the TV never has sound or picture. It never "turns on". Then when you try to turn the power off, neither the remote nor the manual switch on the set does anything. If you fiddle with the power enough, the indicator light on the bottom bezel of the set will start flashing 3 blinks then one blink and keep repeating that. Unplugging the set

50hm66 There is a new bulb in the TV, and it is working. However, it takes several tries to light the lamp before it will start up. If, after I turn the unit off, and come back to it in a couple hours, it will not start at all, and I just keep getting the yellow blinking light over and over, as it tries to start up. Eventually I will get the red blink with solid yellow. If I wait a day, the unit will start again after a couple tries.
Some possible reasons include: New lamp is generic and or has a issue----excessive dust or dirt inside the unit on fans etc.Some of these units had a feature in the menu for quick on where lamp is lit at low level all the time---this shorten ...

I have a Phillips 32PFL5322D/37 tv that is about 2 1/2 years old. Recently the TV stopped working. All I see is 8 red blinking lights when I try to power-up. After reading multiple threads and suggestions I replaced the Power Supply Unit but still no change in the 8 red blinking lights. I have a power aux board coming in the mail and I plan to install. I am out of ideas here. Any other possibilities? It seems everyone is having the same problem with this TV. There must be a reason.
