When I turn on my WS65611 rear projector TV the picture comes on perfect but after a minute it starts going static then the picture will come back on then it goes stactic. This continues for as long as the...

A few things you could and should try, try something on a different input if you are using the coax connection just to know if problem exists that way, could be a bad tuner but that can be got around, also if on all inputs the set does have a hard reset that requires the Mitsubishi remote and a four digit code to enter the hidden option menu.

check the other inputs first please and let me know.

Monitor goes off and on by itself

Hello bjaykaye,

The problems you are having are an indication of a Power Supply problem. The issue could be in the switching power supply or the High Voltage Power Supply. The shutdown circuit is activating which is allowing the TV to play until it detects an over-current event. When an over-current event happens the shutdown circuit will turn the TV off. I would suggest that you check the Horizontal Output Transistor, the HV Transformer, the Horizontal damper diode, and the capacitors that are in parallel to the damper diode. The important thing is to find the component that is causing the problem. If you do not have a background in electronics I would suggest that you get a qualified electronics technician to look at the set.

Thank you,

When I push the on button the green light comes on for second or two then goes out.(will not stay turned on long enough to even get a picture on the screen.Mitsibishi Model # WS-55315

This set has a self check feature--if set has been unplugged it clears the error buffer--plug in and try to turn on set.

When green light comes on and then goes off ON THE FRONT OF THE SET press and hold BOTH the menu and input(device) buttons at same time for at least 5 seconds and release both buttons.

Power light will blink a 2 digit error code like 2 blinks, 2 blinks, a pause and repeat the code for a total of five times.

Let me know what error code you find and I will explain it.

The color goes out on my panasonic PT-47WX49E TV.

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Below are more details for both items. Also, complete repair kits with instructions and repair support are avail from site such as

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. The power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

What you will need to do is convergence. You can get a repair kit from . It includes replacement parts,step by step instructions, support, etc.

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from . It includes replacement coolant,step by step instructions, support, etc.

The screen turns blue after about 2 minutes of turning on the TV

Sony TVs has an Optical Block issue. If there is an issue with the optical block, then there will be green, blue patches or tint on the TV display. Try resetting the TV to the factory settings and try Power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue still persists, then TV may require service. You can contact the Customer relations team and check for the available options. Sony had repaired free of cost for such issues. Hence, contact the customer relations.

The DM is fine if the led isnt blinking. Your set is going into protective shutdown. Try pressing the menu and the device/input buttons on the set both in together for 5 seconds to see if the set will blink a series of blinks pause then blink another series of blinks. Such as 2 blinks pause then 2 blinks, Then let me know what the blinks were and I will assist you with whats wrong

Sounds like a bad digital board to me. Not too hard to replace in those models but, you do have to write down a few settings before replacing it. These settings are available in the service menu. Any questions let me know
