20 Most Recent Mitsubishi WS-73711 73" Rear Projection Television Questions & Answers


LIKELY it is fixable, most landfills will not take this as it contains Glycol which is a toxic material---If in a large city in the USA for example there are people who will come pick it up for free and send to a recycle center.

Also in USA list it for free on Craigslist or in Canada for example kajiji.

the green light blinking is normal if set has been unplugged--when set is plugged back it should blink for about 70 seconds and then go out--then you can try to turn it on---it is the DM unit inside the set booting up.

If the light just blinks and never stops you have likely bad caps in the DM unit---there are kits available for that.

The other possible reason is that so called reset switch may be bad--fairly easy way to find that out and it is more common than you would think, let me know if you have questions.

Tis a common problem. its a safety feature. Some component in the systems heats up and causes an overload therefore the power supply shuts down so that no further damage is caused. If you are a technician then check the critical components like the H-Out, FBT or the video(jungle) ICs. some regulators can also pose this problem..
See a technician if you are not a professional.

All the best

Thats a very common problem caused by weak capacitors on the DM board. When power is lost the caps discharge and when the power is restored they cannot recharge so the timer led will blink non stop. You can get the DM repair kit for your model from www.tvrepairworld.com it contains the upgraded capacitors and the CD with repair instructions.

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. Power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

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.

Picture of a set that needs the fluid changed.

Have you tried accessing the led self diagnosis by pressing the menu button and Input button both in together and hold for 6 seconds on the front panel of the set. It should then blink a two digit blink sequence from the power indicator. which will repeat several times let me know the blink sequence and I will assist you.

Hello,

The cause of this problem is either a bad lamp or a faulty t-com board.

Have the television unplugged for a while, lets say for about an hour or two, then you open it uo using a screwdriver, then you assess the lamp for any fault, if it looks burnt, then it means you need to replace the lamp, but if it does not look burnt, then you have to locate the t-com board and replace it with a new one.

Some of this rear projection television used to have about 1 or 3 lamos, so be sure to check every one of them. Then replace the faulty one.

Take care and good luck
