    i'm not sure i will have to try a dvd

  • txrcaves Nov 06, 2007

    When I first turn on the TV the picture and sound will be fine for a few seconds, then the screen goes blue and there is no sound. This is the same regardless of the source of the signal.

    I have 52 Vac on the coax shield. I belive it is coming from the power supply. I have also noticed that there no ground prong on the plug therefore ground reference is through the ANT A/B jacks if used and grounded outside. How can I further troubleshoot and repair ?

Mitsubishi WS 55413. Ongoing rolling screen.

First check for the coolant/fluid leakage from the picture tube on to the signal board. Wipe it with paper towel and dry it will the hair dryer. I hope there's no corrosion yet.

Mitsubishi WS-65907 rear projection TV HD goes blue.

I would look at the source for the Hd signal as being the problem--if you are using some kind of cable or sat box it will deliver the signal to the DTV input on the back of the set--this is the HD input for this set.

It is possible to have a problem like you describe be one in the set--but very unlikely----have you looked on that green signal board for any signs of Glycol?

Anything that will produce a 1080 signal to the DTV input should tell you if the problem is the set or the source of the HD signal that is causing the problem.

If you have questions or need advice let me know--I am here to help people.

Lightening power.

There will be a fuse in the input to the power supply which most probably has blown because of the power surge.In almost all cases if you replace this it will blow again straight away as a lightening strike can cause a lot a damage to other components. You will probably find there will be some other parts that have gone short circuited & this would need to be investigated.

Mitsubishi WS-65313 Blinking Screen

Does your system have hdmi input. If so hook up cable box, if it has hdmi, to the tv and see if that works.
If that clears up your problem you have a problem with the av board or boards.
I have found that most of the newer systems do not like the voltage and frequency from xboxes, playstations, or computers very well using the rca out and in.
Let me know what you find out. I might have a better solution for you.

Mitsubishi WS-65909 Video Inputs Stopped Working

Finally got a tech to come out to the house ($99 to diagnose).  He determined it was the Doubler Board.  Got a quote from this company to repair it for around $800.  I was able to watch over his shoulder.  The board is really simple to replace.  I just need to find it.
