Popping sounds only during video/ you tube on tv from my computer.


Because of the amount of voltage required to run the older-style "tube" televisions, many problems, sounds and noises occur in tube televisions than in the newer, flat-panel televisions. Sounds occur for multiple reasons, with some being just part of the normal process these televisions run through in order to operate. On the other hand, some of these noises may indicate a problem with the television that could warrant repair.


Worn Insulation
Voltage against metal. Inside your television's tube, there are many wire parts that electricity runs through in order to make the television run. Usually, these parts are insulated with a rubber or foam casing that prevent the sound of the electricity. If the insulation surrounding these components is thin, weak, worn or absent, you are bound to hear buzzing, popping and cracking sounds coming from your television. While this may not mean you have to run out tomorrow and get a new one, the chances are that your TV's tube is working extra hard to make it all happen for you, and you may want to start pricing new sets for the near future. b> Static During Warm-Up b> Just like rubbing your feet on a thinly-carpeted floor can cause static electricity, the same can also build up inside your television. If the noise is relatively subtle, only occurring when you first turn it on, and not overly-disturbing, the chances are that the cracking and popping sounds you are hearing are just the television's way of warming up and getting rid of the unnecessary electricity. Bad Lamp b> Deep inside the heart of your tube television, there is a light-bulb fixture that makes the entire unit light up so that you can see a picture. If the cracking and popping sounds you are hearing tend to go along with the picture on the TV becoming unclear, it could be that the picture tube is failing. It is very difficult and costly to replace the picture tube on a tube TV, so this is an instance where you may benefit more from buying a new television than taking the old one in for repair. Hope this helps.

Loud popping on jvc av56wp74


if the noise is from inside the tv in the back,the high voltage transformer that feeds the anode for the rgb tubes,28000volts probably is arcing.

Green screen and distorted picture sound is good but no picture


It must be connected with the color circuit of your tv, a board connected to back end of the tube. Could be dust, cob web or carbon deposit shorting a transistor. Popping noise if loud enough can be attributed to high voltage circuit fault and picture tube.

Have it service by a qualified person.

Problem with RCA TV Model 27F634T


You almost certainly have a bad picture tube. The green screen was from one of the elements inside shorting out. The static sound you're hearing is the high voltage arcing out through the end of the picture tube to other parts inside the set. It's more economical to buy a new TV than to repair this one.

Sorry to have such good news, but this is one of the ways a picture tube can go bad, and it happens quite often.

1986 tv won't turn on


Great TV you bought.
At this point I would say it might not even be worthy to get the TV fix due to the age unless you can do it yourself.
In my opinion you can save the money from the repair to buy a new TV.
Hope you do not upset with the messenger LOL.

Blurred picture with lot of static


This model has a chronic problem with the crt socket arcing and causing this problem. The only true fix is to replace the crt socket locate on the small bd. that plugs on the back of your picture tube. You can however have some success by locating the focus control on the flyback transformer and slighly adjusting it until the unit stops arcing. If you are not familiar with high voltage safety then please have a qualified service tech perform this repair.

TV pops and shuts off


Its two maybe three issues that your having trouble with. First thing is the convergence. That problem could be a cold solder connection on the convergence IC's or the Ic's have a thermal problem, as after they heat up they go bad. The second is the popping. This could be an issue with the rear channel Audio output Ic intermittanly shorting and shutting down the set, or it could be a bad ground around the picture tubes, or a leaky hi voltage block, or a second anode lead going to the picture tubes could be split. The other common problem with this set is the STR#### regulator IC in the power supply. Now unless your a tech you shouldnt attempt any of these repairs as there is very high voltage in this set and could cause great harm to you. seek the help of an authorized repair shop for Toshiba. Try this # if you cant find one in your area 800-457-7777 Good Luck
