Toshiba 36a42 picture problem

PS issue. The set has been used and abused and has finally had it and died. Get a new one.

I have the same problem, did you ever find a fix for it? Or is the TV dead?

The short answer is no. The reason for that is because it's an analog TV and has a standard tuner which is now obsolete because of the changes to all digital programming last year. You won't be able to use it with out a converter box. I won't recommend a particular brand or model, that would be your choice. Here is a selection of "boxes" available.

The most common cause is the emission of the CRT electron guns are decreasing. They are going out of range and of proper balance in relation to each other for the AKG (Automatic Cathode [K] Gain) circuits in the CRT drive circuits to compensate for proper colour balance and colour tracking.

A less frequent cause are components going defective in the CRT bias and drive circuits.

I would be considering a new TV set with this type of fault condition. The cost of servicing this would be expensive.

If you can see the menus this means the CRT, high voltage, scan amplifiiers, the output video processor, and CRT drive circuits are working. The fault is most likely in the video section of the input select circuits.

Maybe the Toshiba parts department can supply a service manual for your set. With a signal source, a scope, and a DVM, an experienced technician can troubleshoot your set to locate where the failure is occuring.

I have not serviced this model, but in other models I have found the main input select IC to be defective. In some cases I also found a bad voltage regulator IC that supplies the input section has failed.

A common cause is a failure in the one of the scan amplifiers or on the high voltage section. It is also possible to have a power supply fault that will give this error message.

open your tv.At the back you see a plyback,it is big parts of tv with a wire attached to the picture tube,that is plyback At the buttom you wiil see a two knob, the lower knob is for the screen and the upper knob is for the focus.Adjust the lower knob or screen .

try the closed caption adjustments. i had a tv that did the same thing and the captiong did it. turn caption off nd try.

Check the "screen" control on the flyback (lower knob) its easy to hit moving a board around. Try to adjust back to its original setting. Look for where the dust is, it should be on top. Or any marks might help. Other wise adjust slowly, back off if any retrace lines appear, with user settings at there normal settings.

dopy, the problem is leaky tact switches on the control board, have changed out many of these especially on the 2003 model which of course is the 32A43, part number for the switches is 23344443, swap them and your done, BMW Rider
