This question posted more than one time---model indicated prone to all kinds of troubles but this sounds like the light engine (major part) is damaged.

Look on EBay, thats where I find better deals on ballast boards. You can also check on Shopjimmy.com

You are SURE the lamp is good....well...if you say so. However, it sounds like you have made audio connection but no video connection (or lost it or is incorrectly set). Try other input modes. See if you an bring up "setup". If so...you screen/lamp is working.

1. (Lamp may light and go out) suspect bad lamp part # 915P020010 2. Check for 12-volts DC at J-9 connector pin 4 on the Engine Driver PCB, if missing check for an open F9A09 on the Power PCB, if it is open replace F9A09 part # 283P127060 and the Light Engine part # 939P977010 3. (Lamp may light and go out) Check for 5-volts DC at J-9 connector pin 1 and 2 on the Engine Driver PCB if low or missing check C9A37 and C9A38 both 3300 UFD 10 V part # 181P732040 on the Power PCB (part # 930B921002) 4. At power on the lamp turns on and off three times and then the unit shuts down with a red lamp LED (lamp error). Replace the Light Engine part # 939P977010 5. Lamp enable line at J14 pin 6 does not switch to 5 volts after turn on, 12 and 5 volt supplies are good. Suspect the Light Engine part # 939P977010 6. Lamp enable line at connector J14 pin 6 on the Engine Driver PCB switches to 5 volts after turn on and does go to 0-volts (low) after 5 seconds, 12 and 5 volt supplies are good. Suspect the Lamp Power PCB (ballast) part # 939P978010 7. Lamp enable line at connector J14 pin 6 on the Engine Driver PCB switches to 5 volts after turn on but does not go back to 0-volts (low) after 5 seconds, 12 and 5 volt supplies are good. Suspect the Light Engine part # 939P977010

color red blue is running

The model was never a P model, it is I.

I have the same problem with the green light blinking and the T.V will not come on. I have reset it and unplugged it and everything and still nothing. Can anyone help me

a friend had the same issue, he was told it needs cleaning, its normal, and dosnt cost much

How about a little more information and tell me what the set is doing or not doing?

Try searching for a possible "factory reset" for this brand. It will be a secret set of buttons on the remote to enter the default reset menu. I hope that gets you something to try. BTW you should have the original remote or a universal remote with all buttons communicating with the tv to do this. ie numbers, menu, up, down, left, right...

Try "initializing" a "factory reset" power on the tv then on the remote "menu 1,2,3 enter". Start the reset to default and see if the new refreshed settings help.

do the lines go from top to bottom, and are they about 1 inch apart? or do they move diagonally across the screen?

If it is not there or grayed out you may have to try the soft reset first--set also has a hard one but only to be used as last resort.Soft one: set on, menu,1,2,3 enter.

Unless you examine it or it is shattered inside the only way to know is replace it----set should have a blinking light but does not always have that----set does have a self check if you want to try that--will work even if lamp is bad--give you a blink error code.

It does not matter---these sets are so bad (this one) they sell the entire chassis or the light engine which has the color wheel in it and last time I looked the wheel does not come unless you buy the engine.

I would not attempt that if I were you----The lamp itself has a glass lens but any touching will shorten its life---this set also has a optical lens at the top of the light engine but it rarely if ever needs cleaning.

A 37 error code means one of your fans is bad. It would either be the DMD fan, or the lamp fan. Take the back cover off of the set and tape down your lamp safty switch. Turn the TV on and see which fan is not working, and replace.

If you own the model WD-52525 it and the sets made around the same time are all junk----falling apart as we speak and nothing seems to help make a good repair on them.Blinking green light is called "blinking light of death" and I did not coin that phrase but it is accurate. The green light up front that blinks is the Digital unit in the set trying to boot up----one of the many nasty problems this set can have.Not fixable in the home and in my view not economical to repair for any reason---if you want to see some of the other issues this set has Google the model number with "problems" and be prepared to read for a while.
