Take123, problem is with vertical circuit not eprom, could be bad capacitor supporting the IC or the IC itself is bad, that type of problem needs a tech because once it`s fixed you will probably have to go into the service menu and re-adjust the vertical positioning, this of course will require the info in the service manual which you can`t easily obtain, questions? e-mail me back, BMW Rider

Hi. Look for cold solderjoints on the vertical output section. Most likely, the vertical final IC has bad solderings. Using a magnifier, one can see "craters" around the soldering pin/pad. Or just simply re-do all of them. Good luck;

First tv no sound i open his eprom ic leter open ic i saw vertical line

Please don't play with this set. Get it repaired by its authorised service center. It will be best to throw it away, rather than making any repair to it, without proper experience and knowledge. You never going to get this set right by no way hereafter.

Over heating vertical ic

It is quite normal for the vertical ic to be hot. That is why it is mounted on a heatsink. My question is......are you saying you have intermittant horizontal lines at the top? Or occasionally after warm up you experience one horizontal line across the center? Your vertical IC may need to be resoldered. In this case you will have to decide to just resolder or solderwic the solder around the seven pins, clean with flux remover, wipe dry and reapply new solder. If you have (in most cases) White horizotal lines across the top, you need to replace the capacitors next to the ic. Correct polarization on the caps are neccessary. And dont forget to solder the ic as well. And any ground you may find along the way please resolder. Take two aspirns and call me in the morning!

I have a toshiba TP55C81 projection TV. The red The red vertical adjustments stopped working. The adjustmnet knob in the control panel does not effect the adjustment and none of the vertical adjustmen

You need to replace the vertical STK convergence chip but I would recommend that you replace the horizontal chip at the same time as this is likely to fail soon.

The following relates to the repair I have recently carried out to my Toshibal 40WH08B rear projection TV but shuold be very similar to your model. Replace the STK chips with the same type on your model:

On the convergence board PB 9487 (the one with the 2 large heat sinks that the r, b & g guns plug into) you will see two STK392-110 ics connected to the large heat sinks. Replace both of these and readjust convergence in service mode if necessary.

I obtained the replacement ics from Charles Hyde & Sons Ltd (see link below). I ordered the general ics not the Toshiba ones as these are identical as far as I could see and they cost £17.19 each instead of £36.68 each.

You will need to desolder the heat sinks as well as the ics as access to the ic mount screws are obstructed by the conv.dig board (metal cased). Buy a good quality desolder pump if you dont have one.
One last thing I should mention. The white paste between the ics and the heatsink is silicon thermal compound. Without this the heatsinks will not take heat from the ics effectivly and the ics will burn out! I recommend that you clean all of the old paste off the heatsinks and apply new to the whole of the metal plates on the back of the ics before you screw them to the heatsinks. You can get the thermal compound and the desolder pump from the same supplier I recommended for the ics.

Let know if your are having any problems.

If this is a tube type or crt type. Your vertical circuit has a problem. Could be the vertical IC loose connection on its board. Or the vertical ic itself is faulty. If just resoldering or refluxing of its pins doesn't help check some minor cmponent within vertical circuit. Or the vertical ic is defective already.

If your not inclined on electronics never do the repair itself, nasty voltages might caught you.
