Toshiba 3387DB Television

of course check different inputs etc to make sure something did not get disconnected.

This rear projection set uses 3 picture tubes and the set will protect them if there is a problem in the vertical or horizontal sweep circuits that might burn the screens or the damage the tubes.

No simple answer as a lot of different parts are possible for this problem.

You need to convert the component sync signals into a composite sync compatible with SCART. The red, green and blue signals can be connected through as-is.

Any of these will work.

Beano did you get a solution for this? as I'm encountering the same problem

Well, if your horizontal is off frequency and you have diagonal lines then there's no need to look at the Horiz Output Transistor or the Vertical section. You will have to use your scope to check the oscillator freq. and go from there.

this can be in your video cable or LCD Connector issue. but most problem is in the flex cable of LCD. some other cases cannot be fix and replace new LCD Screen.

Does it look like a 3D image?
Would you be able to post a picture of the TV with the mention lines?

Needs Hyper board repair = replace bad caps
PCB not available to buy outright........................T.

Sounds like a bad cap, spray some freeze around till you can duplicate the problem.

1. HORIZONTAL PULLING AND TEARING, MAY ALSO HAVE VERTICAL ROLLING OR VERTICAL BLANKING BAR LOCKING IN THE MIDDLE OF THE PICTURE. CHECK C2C52 10 UFD @ 50 V OFF THE BASE OF Q2C51 ON THE SIGNAL PCB. 2. CHECK C2P05 100 UFD 16 V OFF PIN 3 OF IC2P01 (9-VOLT REGULATOR) ON THE SIGNAL PCB
