If you have a line in the middle it is verticle ic and capacitors that go bad. some times cold solder joints.most of time part and repair is cheap around 85 to 160

At least now you no what your up against when you call a service center

Thanks jay

What is the cause of my 14inch videocon crt tv appears only a single vertical line in the middle


The image on a CRT TV is produced by a beam of electrons which is controlled by a magnetic field to move the beam top to bottom and left to right. A single line suggests that the vertical deflection is working but not the horizontal deflection (left to right). There are a number of components associated with this and requires a competent TV repair engineer to fix. Better to to buy a new TV!

My telefunken has a problem. The guy that tried fixing it says that the tv is in PROTECTION (the light just flashes and no picture or sound comes through. Please help


If the set is in protection mode, that is normally caused by short circuit line output stage, short circuit frame output stage, short circuit audio output etc. It shouldn't be too dificult to fault find, even without a service manual.
Look for an authorised Telefunken service centre.

I have a CRT tv and the picture is just a thin band in the centre of the picture tube. The sound is ok


That is called "Frame Collapse" because the picture "Frame" has collapsed into the single horizontal line.
It may be caused by dry joints or output failure of the frame output stage.
A fairly inexpensive repair.

I turn on the TV and there is only a line going across the middle of the TV. The sounds work the same but there is no picture. It seems as if the picture had shrunk to a very thin line that just goes...


this is commonly known as a frame colapse and could have two possable causes (1) no 28volts comming from the l.o.p.t.x or in english the line output transformer ,to the frame output i/c ,usualy caused by an inline fuse blowing this looks like a very small transistor but with only two legs or (2)the frame output i/c has packed up

Field collaps


MAN/WOMAN I GOT SIMILAR PROB. HOWEVER I AM SHORT OF CERTAIN DETAILS. IT IS ALL ABOUT THE VERTICAL SECTION. THIS IS THE PORTION THAT PRODUCES THE FRAME. IC TDA8172 IS USED FOR THIS AMPLIFICATION. CHECK TYPICAL PIN VOLTAGES AND ASSOCIATED CAPACITORS AROUND. CHECK VERTICAL SCAN COIL IMPEDANCE. TRY FURTHER BACK, THE ACTION OF IC CXA2159S. I DO NOT HAVE ITS PIN CONFIG. I NEED IT.OUR PROBLEM IS HINGED AROUND ALL THESE AREAS.

T.V. overheating in our conversion van


If you suspect overheating then try removing the back and clean out with a long, wooden handled artists brush. Make sure the children are not about and try it with the back off, but do not touch things inside. You may blow cold air if you see what is overheating. See how long it works OK for. If it works without going off (assuming it was very dusty inside), then replace the back. If it needed a fan to keep it working you may find out what needs replacing.
