Very low light but picture and sound ok


Try adjusting the controls for brightness or contrast. If this does not work, the voltages on the back of the CRT needs to be checked. This has to be done by a skilled technician. Do not attempt repair if you are not familiar. There are very high voltages on the back of the CRT which may mean your life.

Picture is dark, so you have to turn up the black level, contrast, etc. is that the picture tube or have you heard of this problem before, maybe something inexpensive and easy to fix


the picture tube is already weak. if you could only have a reduvinator it will be good again, it is a instrument used to reduvinate the picture tube.

Our HP5060N/ HP PL4260N Plasma HDTV made a loud pop sound and then we lost the picture - still have sound. My son was playing Playstation at the time. Any idea what the cause is? Is it worth the cost of...


Hi, I have just experienced the exact same loud pop sound. Then no picture or sound. Just died. Spoke with a rep at HP and was told that this (having owned for 4 years) is out of warranty and the "main board" has died. It will cost $629.00 plus tax to repair. This would provide a 90 day warranty on those parts replaced. It's about the same to buy a new tv! So I am throwing this JUNK away and will never buy HP again. Best of luck to you all!

Toshiba 37XV505D. Sound but no picture


Hi,
Since sound is ok but there is no picture, you should try the following:
1) check whether brightness & contrast controls are adjusted properly. If necessary increase level of these controls.
2) If brightness & contrast are ok and even then there is no picture then most probably, there is fault in the horizontal supply circuitry which drives picture tube and is responsible for picture to appear on the screen. you will have to take the TV to service center.
Good luck and Good day.
Rating the solution is appreciated please.

No picture but sound normal


Check filament voltage on tube, or at the back you should see some glow in the inside of it. Or check first your adjustment settings. Like contrast and brightness setting set it to high.

If you doesn't have any knowledge on electronics bring it to a shop, nasty live voltages might caught you.

Loud static type snap from tv


TV's use high voltage to generate the stream of electrons traveling across the picture tube hitting the screen and lighting it up (thus the name Cathode Ray Tube). It takes about 25,000 volts to do this. In normal air, it takes about 1000 volts to jump an inch of air, so the high voltage transformer needs to have good insulation. It generates the voltage through a technique of charging the transformer's magnetic field with a low voltage of about 140 volts then letting it go where upon it flys back out the high voltage side at much high levels (Thus the common name flyback). A most common failure in a CRT type TV is for the insulation to crack in this transformer which is a unique component for each model of TV and leak out the current overstressing the circuit driving it. You can liken it to a little bolt of lightning getting loose in the circuit and has the same sound on a smaller scale.
It would be well to replace your flyback transformer before it gets worse and blows up something else as well. Best done by a professional used to handling high voltage. The picture tube can retain voltage even when the TV is unplugged for some time, and replacing the anode lead (the big red one) can be dangerous.
Hope Ya Fix It!
