Hello everyone.

I have an old BEKO TV and the problem is that the screen image has moved upwards so you can no longer see the top of the picture and where the picture should be at the bottom is all black.

I've heard this is a common problem with the older TVs so I'm really hoping you guys can help me out by telling me how to fix this.

Thanks.

Thanks for the help Gary, but I should of mentioned from the start that I know nothing about TVs. I took some photos of the TV innades, is it possible you could explain exactly what I should be doing? Let me know me if you need any more phots.

IN THE MIDDLE OF THE MAIN PCB IS A LARGE MULTI PIN IC, IT HAS TEA2029C WRITTEN ON IT, THE RESISTORS ARE OFF PIN NUMBER 5 AND IN THAT AREA, MEASURE THEM WITH A MULTIMETER OUT OF CIRCUIT AND REPLACE IF NECESSARY, BEWARE THERE ARE STILL HIGH VOLTAGES PRESENT IN THE TV EVEN WHEN UNPLUGGED.
