Question about Mitsubishi WS-65711 65" Rear Projection Television

1 Answer

TV Shuts off by iself!

Mitsubishi WS-65711 TV turns off by itself. We had the convergence chip replaced about 8 months ago. The problem has gotten considerably worse over the last month. I noticed horizonal lines at random points onthe screen before it shuts off... We have tried resetting & unplugging the tv. Nothing works. Any guidance would be greatly appreciated. TV is only 4 years old. WILL NEVER BUY MITS PRODUCTS AGAIN after this bad experience. TV never moved since purchased new!!!

Thanks,

Larry P.

    Just an update... We have done nothing new with the TV and it has worked perfect for close to a month (so far)! I have no idea why it woukd shut off consistantly for 1-2 weeks nd then work perfectly for a month. My wife said it did shut ff once a few days ago but has been fine since. Loose connection??? We did have the convergence chp replaced over a year ago...?



    Any ideas???

Don't feel bad about Mits. All the projection companies and all the new TVs have markedly poorer reliability than the good old CRT types. You should see all the class action lawsuits against even some of the best companies!

The power supply section is not working.
Common possibilities are:
- Convergences amps have failed overloading the supply
- High-voltage section (flyback transformer) has failed
(happens sooner or later, about 8 years typical))
- CRT tube has failed overloading the supply
- Power surge has popped the power input circuit.
(Fuse, rectifier diodes, turn-on relay etc)
- One of a hundred of electrolytic capacitors has failed short overloading the supply. They dry out with age, are cheap to replace, but hard to find which one it is.
- Or any of many other possibilities.

In short, you need a experianced tech to troubleshoot this.

Red distorted color near top of screen not having much luck with trying to converge the lines on the tv set form. already tried factory reset


Reset will not cure a convergence problem.

this model (ws-65711) uses a single convergence chip located on the middle circuit board (see photo).

If convergence is skewed and will not adjust in customer menu the chip needs to be replaced.

Good news: I have start to finish, step by step instructions for this repair in this set. They tell you everything you will need and exactly how to do the repair.

No two sets with convergence problems will look exactly the same but I will also attach a few photos of this kind of trouble.

If the photos or what I have told you told you something you did not know and you want the instructions (free) rate this solution as very helpful as I do this here for free.

Would you like to bypass, defeat or reset your Mitsubishi 65711 HDTV Parental V-Chip parental lock? Have you forgotten your V-Chip passcode or password?

If you forget your V-Chip passcode, you can view the locked TV without entering your password.

When your passcode is requested, press the number 9 and the QV button on the original TV remote control at the same time. This process temporarily unlocks your TV.

When you enter the V-Chip Lock menu, pressing the number 9 and the QV button on the original TV remote control at the same time will delete your old password and prompt you to enter a new passcode. Pressing HOME at this time will cancel the entire passcode.

I hope that helps.

I have a WS65711 - 3 months ago I replaced the Convergence - Today the TV was on then turned itself off. I have tried to turn on but it just turns off after 30 seconds


Did you do the diagnostic self check:

when green power light goes off on the front of the set press and hold both Menu and Input(Device) buttons for 5 seconds and release both.

Power light will blink two digit error code like: 2 pause, 2 and repeat it at least 5 times.

Let me know what code you find and I will try to help you.

Mitsu Proj TV WS-65711 needs Converg IC chip. Part Co$t + labor?


There is either a pair of STK392-570's, or
a STK393-110. Probly also 1 or 2 pico fuses for the +/- 26v line in the power supply.
Parts aprox 80.00 to 90.00
Labor 150.00 to 180.00
Plus service call fee if any.
So figure it up from there. Labor cost does vary from location to location. I do feel confident that capasitors are not causing this problem in the way you explained the symptoms.
Hope this helps,
