Mitsubishi wd-65731 lamp light solid red

I was watching tv and I went to put my son to bed and came back and it was off and wouldn't turn on. The lamp light on the front of the tv was flashing yellow and after reading everybodies issue with this I tried to re secure the lamp door. Now the tv will turn on but no picture or sound then it shuts off and has a solid red lamp light on. I am about to throw this tv away!!!!! I did replace the lamp in November 2013

Hi Sally Jo, Unit powers on and works properly for a while then shuts off with a red lamp LED (lamp error). Suspect bad lamp part # 915P020010 2. 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 3. 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 4. 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 5. 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 6. Check for 5-volts DC at J-9 connector pin 1 and 2 on the Engine Driver PCB if missing replace the Power PCB part # 934C148001. Hope this helps!

SOURCE: I have Mitsubishi WD-62525. Last

that is a common problem with that model you will need the v26 power pwb repair kit and the V26 FMT pwb repair kit. You can get both kits at the following link which includes the replacement capacitors and instructions on where the capacitors are located. Heres the link.

You have to take the TV apart. Pull the electrical chassis out and look for bad electrolytic caps on the boards. The red LED probably means the 2 - 3300UF caps on the power supply board are bad. You can tell if they are bad by the fact that their tops are puffed up and they may or may not be leaking brown fluid. Compare them against the other caps on the boards and you will see how they have flat tops.

BUT before you take the TV apart you can check the error codes by pushing "menu" and "Device" at the same time and holding for about 10 seconds. The status light will blink two numbers. ex. one flash pause two flashes is 12 Error Code Probable Cause

12 No error detected
22 Recovery from momentary Reset
32 Lamp Cover open
33 Air Filter Cover open
34 Lamp abnormality
35 Chassis Fan failure
36 Exhaust (Back Cover) or Lamp Ballast Fan failure
37 Engine (DMD or Lamp) Fan failure
38 Excess Lamp Temperature
39 Excess DMD Temperature
41 Short Detected
44 DVI Cable (between Chassis and Engine) disconnected

You can buy replacement caps from Mouser electronics online. There are plenty of solutions detailing how to do this already posted.

Please make sure lamp cover is fixed properly in its position after lamp replacement as it has to press a safety switch located nearby lamp cover.
3 times red blink problem is related with that lamp cover safety switch only.
Hope this will help.
Thanks.

Samsung DLP turns on and off - cycle repeats


make sure put the lamp door back before trying to turn it on because they have switches on them that allow the tv to turn on. If that is ok you probably have a bad ballast.
Call a local tv repair shop to further diagnose the problem.

Had a power outage while watching tv. Then 3 blinking lights.


This is an on-going problem with DLP sets. Normally you shut the set off and the cooling fan cools the lamp down and then it shuts off. In your case, of which it's not your fault, however your lamp has taken a major hit by not properly cooling down, in turn, you need to replace your lamp at this time.
I suggest in the future if you have an electrical storm and a chance of a power outage while your watching tv, I would'nt play that model or any other model of a DLP set.

Blue light and lamp light flashing, no picture.


Look in the owners manual for the directions on how to remove the lamp. Your model the lamp goes in from the front on the left looking at the TV. There is a thumb screw in the back on the corner holding the left front speaker on. Under the panel there is another thumb screw holding the lamp door on. You will need a Phillips screw driver to remove the lamp. You will most likely find that the lamp is bad. You will either have to order a lamp directly from JVC, a service center or a parts distributor.
