My crt tv no pics but good sound


In a crt television, you have a special power supply for the huge voltage for the tube. That can be defect, but also the heater in the back of the tube can be defect. Actually more defects can make the tube is not working, while the receiver and the audio part still work fine. Could be a little thing, like a bad soldering place on the mail board, but be aware it is dangerous to open a CRT, because of the very high voltages. (Up to 30.000 volt on the tube) and the voltage can be there on the tube and in capacitors.
Don't spend to much money for the TV, because the new flat panel TV's are not that expensive anymore.

I have a 1990s JVC tv that we were wattching the other day then we smelled a smoky smell. Then horizontal lines and staticy sound started to go through the tv. We tried canned air to clean the vents a few...


That tv is very close to catching on fire. UNPLUG IMMEDIATELY. When electronic equipment is old they dont just stop working sometimes. Sometimes the electrical current starts burning the wires and the dust inside. there is a definare odor to electronics burning or shorting out. smell around the air vents in the back of the TV. youll know if wires were burning its a distinct odor

We have an 8 year old jvc i'art pro that has s problem with the colors. It has green lines going thru the pic and it looks a little blurry. Does anyone have an idea what could be happening and how to...


Sounds like to me that the green CRT is going bad possibly. You can take a ruler or something non-metalic and tap the bottom of the crt GENTLY and see if that helps at all....Sometimes the CRT'S get a piece of debris from inside the tube that drops across the plates of the tubes and causes weird issues.... Tapping on the neck of the crt GENTLY vibrates these pieces off and vaporizes them and then picture goes back to normal. If the set is 8 years old and you watch a lot of TV, I have seen the CRT'S actually worn out physically. Then it isn't worth fixing at that point and your best bet would be to purchase a new tv. If you have any other questions, don't hesitate to email me back. @ zx1400jay@hotmail.com Cheers.... HDTV GURU JAY

Current value of a jvc 32 inch color tv 8 years old


The street value would be 100-150 dollars. If TV is a cheap model or abused or very used, you should pay less.
Consider a Sony or a Toshiba in tube style since all are cheap now.

17 yr. old 35" RCA loses color intermittently. Picture & sound ok


Three guns Red Blue and Green in the picture tube of an old CRT set. If one of the guns goes out it effects that color. Sounds like one of the guns inside of the tube is going out, To costly to replace for such an old antilog set that will have to have a convertor box next month anyway.

Color problem


Please fine tune those B/W channels to obtain color picture. If TV is more then 4 - 5 years old, it needs resoldering in tuning area or might need replacement of IF block.
