I have a Mitsubishi TV and had the same problem. There is a mirror that moves to control each pixel. When some of them fail to move you get the white dots. Google your problem and a company will come up(sorry forgot the name).,you can buy the new part from them and they have exact utube videos to help you do the repair. Took me about an hour. Part was around $150. Very rewarding feeling when you turn the tv back on with no white dots.Still dot free after two years

Could be either. Open the manual for the TV and find the section for screen resolution.

Is there audio and is when was the last time a welcome screen came on (in other words, are you even getting that anymore)? I have the same TV but I only get the Mitsubishi Splash Screen only comes on when the TV powers off so I'm a little confused by that. Also how bad were the vents and filters when you cleaned them out and how is the ventilation behind the set? Have you checked the lamp? That's a two year-old set, now so I'm kind of leaning on you needing a new lamp. I had to have mine replaced last summer. You're supposed to get 4,000 - 6,000 hours out of them but depending on your environmental conditions, that lifespan can be dramatically reduced as dust buildup and poor ventilation will cause it to overheat the lamp and normally before it's going to go bad, the TV knows this and starts getting hinky as you described (will come on but then shut-off, etc.). In my case between the wife and three kids and the dad (me) who only gets to watch his shows on the DVR after all the kids are asleep, our set is on 8 - 11 hours a day and longer when I watch the kids at home two days a week so I easily blew through the lamp lifespan in 18 months.
You should check the lamp. Refer to your manual, but it's only two screws in the lower right of the back of the TV, Use rubber gloves as well. If it is the lamp go to Mitsubishi's website and order them. They're OEM and only $100 and cheaper than any of the after-market ones. Also Mitsubishi warranties them and if you need it immediately, you can call them to place the order and just pay an extra $50 for overnight delivery. I've had to do this my TV and my in-laws and I've been very satisfied with the Mitsubishi customer service.
Let me know how it turns out.

Hi, if power indicator/ green light does lite or blink then it is problem with power supply section.
Depending on actual model number most of these sets have a self check.
When green light goes out: On front of set press and hold both the menu and input (device) buttons at the same time for at least 5 seconds and release both. Power light will blink a two digit error code like: 2 blinks, 2 blinks, a pause and repeat several times and if that does not work then you have to apply the solution below....

Solution... The repair procedure to replace the four (apparently inadequate) either 1000uF/25 volt or 1000uF/35 volt capacitors in the "DM module" (one of the two onboard microprocessors). It is recommended to install either 1000uF/25 volt or 1000uF/35 volt capacitors as replacements, so that they will be more than ample to handle any voltage spikes that will occur.

A non-functioning radio in a Mitsubishi Pajero 2006 could indeed be caused by a blown fuse. I recommend checking the fuse box for the radio and inspecting the radio fuse. If it's blown, replacing it may resolve the issue. However, if the fuse replacement doesn't fix the problem, there could be other underlying issues with the radio or its wiring that may require further diagnosis and repair by a professional

Mitsubishi doesn't publish those diagrams to the public.

You should be able to use a universal remote. It will search the frequency for you. TYVM Please leave feedback

Since this is a powered subwoofer, the problem is most likely in the electronics. The most likely component in the amp would the output device. You could look inside to see if it actually has any discreet components in the output. It may just be a single integrated circuit. If so, many of these i.c.'s are dirt cheap, and can be purchased from many electronics parts outlets.
