I had a problem with a new VHS VCR National NV-340EN ----the customer complained that the picture is very unstable. The problem was that a small mice got stuck in between the Guide Pole and the slot, in the play mode one guide pole could not reach the end because of the dead mice, after removing the dead mice and cleaning the area the set operated normal. small creatures usually creep inside TVs and other electronic equipment and create serious problems.

To know the values of burnt out resistors, pl read Jestine Yong's book on it. To my knowledge, there is no match to the packed infos and secrets that his books give!

In reply to Albert van Bemmelen.

Thanks, Albert. Very useful information. I visited the link you've recommended about degaussing. This link is now in my browser favorites.
Thanks again.

Very well explained, in fact i have a similar kind of problem in my old TV, i thoroughly examined exactly the way you described and i found the faulty IC LA78045.

Now that i have located the fault, on the brief check i also came to know about the burn out resistor. But unfortunately am unable to find the Resistor value. Suranga can you help me finding the value of the resistor. Since my TV is old and unable to get the schematics for it.

Your thoughts will be very helpful for me.
Please, reply me.

Thanks
Saikrishna
