Question about Grundig Televison & Video
I have an old Grunding 28" TV with blurring picture problem. The technician told me that the 'focus piece', a small flat item at the back of the picture tube, is not working and has to be replaced. He doubted whether I can get it in Bangalore, where I live.
Can anyone help me located this piece?
Alternatively, what can I suggest to the technician to do?

SOURCE: TV focusing problem
It's good that you know how TV's can bite, I'll still have to post this in case someone having your problem and reading isn't aware of this and feels lucky- If still under warranty or if you have no electronic repair experience you should take the set back to the shop or to a repair person. Some of the solutions described below can be dangerous, TV's are very hazardous to service. Even when plugged out, TV's can store very high voltages. could be a problem with the screen potentiometers block. should be located on the chassis close to where the HT lead passes on its way to the picture tube. Good luck

SOURCE: Tv out of Focus
Well you did start out good, thats cool, now we have to define focus, Is ir blurry around the edges as well as the whole Picture? If it is, it could be the picture tube, A bad solder connection on the tube socket, and yes it could also be the flyback transformer.

You didn't mention if you saw fine white diagonal lines running through the screen from top to bottom. If so, you likely have a shorted Picture Tube which is not usually fixable. If there are no lines seen running through the screen, then it is possible the High voltage transformer which also has a screen voltage and focus control built in that could be bad. I would expect the cost of that part to be about $100, so the repair cost total could approach that of a new set I would guess.
