FREQUENTLY ASKED QUESTIONS
Things you should try before bringing your unit in for service.
VCR's
Always the first thing you should do if the VCR in not working right is to unplug the unit from the AC power plug for about 10 to 30 minutes. This will reset the computers inside the unit and sometimes fixes strange problems. This hold true to all computerized equipment. (TVs, VCRs, microwaves, stereo equipment etc)
Cleaning and Lube seems to only fix mainly picture playback problems (plays in all snow, no picture, happens all of a sudden) and now all tapes I try to play are all snow and has sound. Cleaning and Lube a lot of times will fix this problem. You may want to try a cleaning tape, but only try is once or twice because they are very abrasive and can damage the video heads if you are not careful. I would suggest having cleaned and lube at least once a year. It is the lubrication process that will give you the most life out of your equipment.
TELEVISION REPAIR
If you have color patches in the corners of the screen, this could be caused by a
strong magnet like a speaker that may have gotten close to the screen at one time.
This will magnetize the metal grid in the picture tube causing the colored patches
to appear. Normally you would use a degaussing coil to fix this problem but You can
fix this problem your self as long as the problem is not caused by something in the
degauss circuit it not going bad inside the TV set. Try taking something with a strong
AC magnet like an old gun style soldering iron. Holding the iron on its side. Turn
on TV and hold on the trigger for soldering iron and move in close to the center
of the screen. You should see a very bad wavy distortion on the screen. Start from
the center and in a circle motion move to the outer edges and then to the center
again. Move the solder iron as far away from the TV screen as possible before turning
it off. This will help de-
Snow picture or bad reception.
Be sure and check all cable connections. Replace cables when you are not sure. Try
playing a video source to the TV, like play a tape on a VCR on channel 3 on the TV.
If the picture looks good playing back to the TV and nothing or lots of snow then
the VCR is disconnected and cable is re-
Dead set, Will not turn on.
There is lots of things that cause this problem. If you have checked all electrical connections and power switches then unit will need to be serviced.
Causes
Power supply failure. or something in the High Voltage section may be shorted. You can check the fuse inside the set If you feel like a small challenge. Be very careful because there is a lot of high voltage inside the set and just because the set is unplugged from the wall does not mean you can not get a bad shock from the components on the inside of the set. You must replace the fuse with the exact type and size that came out or you could damage the set a lot more when plugged back in again. Fuses normally blow for a reason like a short someplace inside the set. It is very rare that then I replace a fuse the set works fine. Maybe you could have about a 5% chance that a fuse fixes the problem. I would suggest you bring the set to a qualified repair shop to be on the safe side to be checked out.
I have been servicing equipment for a long time and some model TV's and VCR's has repeated problems. If you let me know what kind of unit it is, age of unit, manufacture I may be able to give you an idea of repair cost if I have seen the problem before on other sets.
