SOURCE: Mitsubishi WD 52525 lamp replaced, no picture, red light

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.

SOURCE: 4yr old Mitsubishi DL 52525, HDMI input vide problem

Are you sure its the TV and not the source? Are you sure its only the HDMI port on the TV? The only reason why you must HDMI is to get 1080p and your TV doesn't support 1080p. Its supports up to 1080i. Your TV has a native resolution of 720p which means it can accept a 720p image and not need to scale it, so the picture will look the best at 720p but will support 1080i. I would use component cables to connect your sources and set them to output 720p.

Mitsubishi tv WD-73640 wont turn on. 4 red light then 8 yellow lights


Hi, if you power your TV on and see a black or grey screen, it may be on the incorrect input. Inputs get changed when switching the TV input for dvds or video game consoles. Look for a Source or TV Video button on your TV remote, not the cable remote. Before doing this, please make sure all connections are secure. I hope this helps or reply with more questions.

I HAVE MITSUBISHI WD-73640 AND ITS SHOW THE GEEN LIGHT BUT DOESN'T HAVE PICTURE OR SOUND


The first thing to replace is the lamp. Google your model number and "lamp" and you'll find several sites that sell them. It isn't difficult to replace yourself and isn't very expensive. Good luck.

Looking what i can do to fix. Have a Mitsubishi TV 3D DLP WD-73640, Replaced bulb, and still have the red LED flashing 6 times to the Yellow led flashing 1.


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience.
Check the lamp ballast too.

Sounds like you need to replace the lamp. An original Mitsubishi lamp will last 7 to 10000 hours. It's a no brainer to replace. Buy the lamp from Mitsubishi or a dealer. Do not buy one over the internet. Those are awful...
