My TV goes 'out of tune' when the picture is white

[AussieTrader]

Hi, I wonder if anyone here knows the problem with my TV. Its an old
NEC, from 1986, model N-1586, which still works as good as new except
for 2 problems. One is that the remote can no longer switch the tv on
or off and the other is that when the tv picture is mostly white, such
as many adds with a white background, the channel goes out of tune!
The audio is inaudible due to the noise and the picture is very fuzzy
and can just be made out. As soon as the picture is no longer white,
perfect. It does this on every channel.

Any ideas are welcome.
THanks

Well .. there you go .. if someone wants to fix an old television and maybe
learn something as well as save some world resources would not it be the
function of this group to help?. but of course this group is only frequented
by ppl with nothing better to do than be lamers and those who write rubbish
replies like this would be better served if they spent thier vast amounts of
free time visiting groups designed for the posting of humorous pictures etc
as they supply no useful answers here!!!!

1. We are not long distance TV techs.

2. Working on TVs is *highly dangerous*.

3. Diagnosis of TV set faults by NG post is an absurd idea.

4. The OPs words showed he did not have a clue and should not touch
any TV.

Why would I bother writing here if I was going to do that. It could be
something as simple as a cap worth a dollar. Its a brilliant tv which
has outlasted many others over the years. The picture quality is as
good as the new ones of today. But if you insist, send me 300 bucks
and I'll take your advice.

PS I think the digital transmission may have something to do with this
because its only been playing up since their introduction...

You may have 2 separate problems. My Hitachi Fujian remote had trouble
switching on and off with the remote All other remote functions worked. No
amount of cleaning the remote helped. I bought a generic remote which works
very well.

A thought or two.

Your older TV may have insufficient selectivity to reject adjacent channel
interference from the digital channels. Try using a VCR as the tuner and
adjusting your TV to the output frequency of the VCR.

Most unrepairable remotes have been sat on. Most repairable remotes have one
or more of these problems : -

Accumulated gunk from food, soft drinks, and/or finger cheese. Clean very
gently with propriety PCB cleaner.

Dry joints. Use an eyeglass to particularly check the connections to the
ceramic resonator/xtal. These seem to be caused in part because the
resonator is not firmly attached the pcb with glue. Less common are the
connections to the IR output LED.

Worn out contacts. Can sometimes be fixed with conducting ink pens.

Regards,
Bill.
