Suddenly double/triple images, bowed red at the bottom

I have a Toshiba 53H71 rear projection TV which has been great, but suddenly it has double/triple images and bowed red at the bottom. I've read something about changing IC's, but can someone confirm that? If so, what should I do?

    I just want to make sure, since the link that I was given was for a Pioneer TV, and mine is a Toshiba 53H71. Also, I have bowed RED at the bottom, and the example wasn't red.

Yes there is a possibility that the convergence ic or stk's have gone bad. they are usally the big ic on the beg metal head sinks....if you have any exzperience soldering you may be able to replace them....if not dont try it.. there are 2 that cost about 20 dollars apeaice a repair shop may charge 150 (or least ours do)... once you replace them you also have to go into service mode an make adjustments.,,something a non tech should not attempt

Yes, the convergence IC's need to be replaced. If you are not experienced in TV repair, I would recommend getting a qualified repair man to do it for you.

Here is a link with instructions on how to do this, if you feel adventurous:

    The procedure is similar. Only the actual location of the STK's on the board will vary.

My Toshiba 53H71 rear projection TV's picture looks like double vision with a heavy tint outline how can I fix this???


Hi,
Double vision/ picture problem occurs due to failure of convergence output ICs in rear projection tv and it is common problem of projection tvs.

Hope these info will help.

You probably have a convergence IC going bad. This is a very common problem. They run hot and wear out over time.

The words on the screen is doubled or trippled.


Go to the picture control menu and turn the color to minumum so that you are watching a black & white picture. Do this to determine if the color offset affects the overall screen or just the lower corner. If the center is off, go to the convergence adjustment menu and align the red and blue onto the green as described in the owners manual. Some models also allow you to align the outer edges as well. If the bottom is still bad you may have a problem in the convergence circuit. If the outlines are not seriously bowed or distorted a minor convergence toutchup by a qualified technician should correct the problem, otherwise parts are involved and the repair is considered major.
