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.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/laura_08254539050d64db

SOURCE: mitsubishi wd-62825 dlp

The WD62825 has a Digital Module located on the left side of the chassis looking at it from the rear of the set. It's housed in a metal box that can slide out of its holder after removing the trim screws.
The module has its own power supply board and there are a group of 16v/1000uf caps on that board which commonly fail causing the constant flashing standby light. Further back on the module is a small board about the size of a matchbook called the E2P module. Its SMT (Surface Mount Technology) caps also commonly fail which can cause the same symptoms. Techs can tell whether the E2P has failed by simply removing it, hooking the DM back up and trying to power the set. If it powers on the picture won't be much good - but at least you can tell what's keeping it down...
Back to the caps on the pwr board. If they've failed they usually will buldge visibly on top. And ESR is almost not necessary. In any event that's the nuts and bolts on this model.
Is it a job for a layman? Yes and no - you might strongly consider a tech if you don't feel comfortable removing all the connections that the DM has with the signal board. There are about six - multi-pin - wired connections to unplug and then sliding the DM out of the unit and carefully removing the screws and latching to take the DM top cover off...
Hope this helps.
Bill

SOURCE: Mitsubishi WD-62525 yellow blinking status light

Check that the lamp door is closed all the way. There is a saftey switch that closes from the door being on all the way. If not the status light will keep blinking. There is also a switch on the air filter door.

The lamp is either defective, not connected properly to the wiring or plugs (careful alignment required on the two connections), wrong type bulb, or the front panel is not replaced properly to trigger the panel sense switch (lower right side of panel)

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.

Black screen

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...
