I was just given this t.v because friends couldn't figure out what is wrong with itl. The colors don't line up right,looks kinda blurry depending on the lighting of the program being watched. How do i fix...

According to the manual:
1) go to the "TV Main Menu"
2) Select "Screen"
3) Select Adjust Projection TV (obviously only if a projection TV).
This then allows you to adjust the TV's 3-colors. Selecting GREEN CENTERING brings up a control panel that lets you center the green projection tube on the screen. Selecting RED CONVERGENCE or BLUE CONVERGENCE lets you align the Red & Blue projector tubes. Centre the green projector tube 1st. Then adjust the red & blue until the test pattern on the TV screen appers white.
Good Luck!

Where is the air filter

No one seems to know what they are talking about when it comes to this issue. I had the same problem for a couple of months. I looked up and down the internet for answers and manuals and came out empty handed. I didnt want to pay a repair guy so i decided to take on this filter problem myself. The OSD should say Projector Fan Filter Unit Needs Cleaning. The fan filter unit they are talking about is on the projector itself. That means you have to remove the back panel. I placed the tv on a blanket screen side down. Revome the board inside the stainless case and remove the projector unit. You have to unplug a few cables...thin gauge wires so be careful. Underneith and on the side of the projector are two foam filters. I vacuumed the heck out of them and its been working fine. You could try getting away with removing the front panel to the right of the lamp. you will see the small foam filter to the left of the projector but there is another one under the projector. Try vacuuming the best you can. My tv was pretty dusty inside so I'm glad to dug in a little deeper.

The screen seems dark and blurry

take off the front panel carefully, usually 2 screws around the controls. Next, stick your head in and look at the red green and blue tubes. see if they are dirty? if, not look further into the tube using aflaslight and see if there is a white pasty looking substance inside. IF so, you need to clean as you have bacteria growing in the cooling fluid. A big job and you need the gaskets, can order from Mitsubishi tech support..good luck be careful.

Red screen and only red bulb powers on.

The red tube and the red crt board sound like the problem. these would be the first thing that needs to replace 250 for tube +50 for crt board. + labor about 300 to 500 to repair

Mitsubishi VS-4541 too much red

The set is old and the picture tubes are probably weak. you can pop off the front grill, remove the protective panel to expose the picture tube sockets. On the sockets are controls to increase or decrease the intensity of the colors. The red is on the left ,green center and blue right. Go to a B&W picture or turn the color off, then adjust for the best grey screen.

Mitsubishi VS-50501 - Black Screen

Is the power light staying on? If so press imput and menu together for 5 seconds to see if the set will blink a 2 digit repeating code. If that doesnt work. Check for CRT coolant leaks on the boards. This seems to happen alot as do faulty capacitors. Coolant leaks will be located on the chassis directly under the tubes they can cause corrosion and prevent your set from starting especially in the VS models.
