Question about Standard (CRT) Televisions

1 Answer

Constant sound static and picture jumps

I removed the back cover and carefully vacummed as much dust off as I could, as suggested may be the problem. This made no difference. Is there something else I can do myself/

You don't mention the model, but your symptom is common for many brands of TV. Solder connections inside the tuner go bad and cause the kind of problem you are having.

When the trouble starts, try tapping on the back of the set where the antenna or cable connection is screwed on. You may find this causes it to clear up or at least have some effect. If so, the problem most likely would be cured by repairing the tuner. This involves taking the tuner off the circuit board, opening its cover, and resoldering the connections that are usually visibly cracked.

This is probably not a repair you could make yourself, unless you have some experience with electronic soldering. But a service call would be less than the cost of a new TV. If you decide to go with a service call, make sure to tell the servicer you'd like the tuner repaired. Some techs will just give an estimate for replacing the tuner because of time, but opening and repairing the tuner does not take that much longer than just replacing it. And it saves you the cost of an expensive part.

The television keeps buzzing, can i fix it myself?


I am not familiar with this model. A lot of TVs do have cooling fans installed to keep power supplies and processors cool. If a lot of dust has impinged on the fan blades an imbalance may be caused. The imbalance may resonate as a hum through the TV frame. The answer may be simply to remove power from the set, access the interior of the TV by removing the back, typically. Once you have access bond yourself to the frame using a free hand or bonding wire, wrist strap with alligator clip. Locate the cooling fan or fans and inspect for dirt or dust on the blades. If there is dirt or dust on the blades, using a vacuum and small brush gently remove the debris from the fan and surrounding area. Be careful not to make contact with electrical components. Even though you have power removed some capacitors may spark you. Also you don't want static sparks from your hand or equipment to arc to a component and possibly ruin it. Once satisfied that the units are clean, replace the cover(s) and plug it in to see if the problem was corrected.

My sony triniton KV36FS10 blinks standby and no video just audio


If you have sound and feel the static on the front screen you have audio and high voltage---I would suggest one simple thing---with back off look carefully in the neck of the picture tube--should be 3 dimly lit lights there --the filaments for the picture tube--are they lit or not?

Rare for this model to have sound and not a picture or brightness on the screen--usually a shutdown circuit will activate.

Let me know what you find or if you have questions.

TV video/audio problem


It may not need repair or replacement.
Unplug the set at least overnight; the CRT (picture tube) has voltages that may be as high as 30,000 volts and take time to bleed off. Believe me, it stings if it bites you.
Remove the rear housing of the set, then use a clean (preferably new) 2-3" paint brush to whisk away any dust deposits you see. This works best with the nozzle of your vacuum cleaner near the area you are cleaning.
The problem you describe can be caused by an accumulation of dust that is picking up moisture from the air and temporarily creating a path for high voltage to discharge which can cause all kinds of strange occurances such as you describe. The warmup of the set dries out this moisture removing the discharge path.    If you don't remove this dust buildup, it will eventually damage the high voltage circuit if not others as well. That high voltage is a healthy static charge and wasn't designed to supply a lot of current which it has to do when discharging.

Picture jumping


If this jumping is accompanied by a sharp snapping sound, it may be the high voltage circuit discharging to chassis. Leakage can cause the jumping and a discharge can momentarily blank the picture.

If you want to try a 'cleaning cure,' I suggest you pull the plug (not just turn it off) for several hours, preferably overnight. Sets of this size can carry enough static charge to punch a hole through your thumb if you get careless.
Remove the rear housing (shouldn't be more than 6-8 screws) and using a clean paintbrush, and possibly a vacuum to **** up the dust, clean it well and pay special attention to the area around a largish misshapen black plastic object bigger than most anything else and connected to the back of the picture tube via a fairly thick cable.

On and off picture and color weak Sanyo HT30744


I had the same problem with my refurbished HT-30744 model and my mom's HT-32744 model. It was either try to fix it or buy a new one, so I figred had nothing to lose.

I removed the back cover, unseated the picture tube driver board from the neck of the picture tube (it just pulls off), put on a dab of di-electric grease on the connector on the card, reseated the card, removed and re-applied more grease, reseated the card and the picture has like new for 2 weeks now!

This was a very easy fix.

Toshiba 36A43 36" turning off and jumping on certain shows/commercials


I need to know a bit more. Does to sound give any noises when the picture is jumping? Reason is this would suggest the high voltage breaking down, which could be caused by dust or very high humidity, so check the location of the set. If dust has collected inside you need to clean it out with a long artists brush, but beware if you do not know about high voltage danger. Dust can also cause overheating and shutdown. Is it only the satelite box which causes trouble? If so then you may need to alter (attenuate) the input level of the Video signal. Could you contact the dealers?
