Question about Mitsubishi WS-55809 55" Rear Projection Television
When tv is turned on the blue indicator light displays then it goes to red
I repaired one these. The convergence board is bad. You will have to change the two STK Ics. These will have, I believe thirteen pins, mounted on large heat sinks.. And that is not the only problem. You will need to resolder this board as there are as many as 15 bad grounds. This board is very thin and you need to exercise care pulling it out,desolder, install and solder in the new ICs. Once again this board is very fragile. Another name for this board, is the signal board, look for all the RCA jacks and RF connections on it. Thanks for asking

SOURCE: Lamp light turns red
Yes this is the signal for a bad lamp. Other things can cause this. 1. Look at the new lamp. make sure it still looks good. not broken with little glass pieaces in it. 2. When you turn on the tv, put your ear to the lower back part of the tv near the middle. Listen for the start up of the color wheel (a low high pitch sound only at the start up of the motor). If this is good you will here a ticking sound only if the lamp dose not light.
Now with all this info. If the lamp lights (as seen from the back of the set) and goes out after a few seconds and you did not here the color wheel spin up, the color wheel is bad.
If you here the color wheel spin up and no ticking sound, the Ballast is bad.
The ballast part no. 939P978010
The color wheel is not avialable from Mits. You will have to replaced the light engine. It cost to much. Just buy a new tv.

This set was designed in such a way that when it is unplugged and plugged back in the LED will blink for around 90 seconds and then stop. During that time you cannot turn the set on. This is the amount of time it takes for the Digital Module to boot up. These units have a problem with some capacitors going bad in the Digital Module and when that happens the LED never stops blinking. You need to contact a qualified repair shop to get it repaired. I have repaired many and the cost is around $250 to $350 depending on where you live. That set is well worth the repair cost.

Once the status light blinks 3 times, this is an indication that there's a problem with the lamp. The lamp may need a replacement.
If you replace the lamp, but get the same problem, check the inverter board.
If you're not sure where the inverter board is, then you may need to contact a pro for your safety.
Good luck and have a good evening!
