The screan is too dark while I am watching tv

If a conventional picture tube type set it will have a high voltage transformer inside with a focus and "screen" control--in this case the screen needs to be adjusted up slightly.

Adjustment is inside the set so you have to have back off and be careful as high voltage is present when set is on (need it on to adjust the screen control just up a tiny bit).

I have a JVC tv only 1 year old and the picture is getting dark.

Sorry to tell you but JVC is a well-known un-reliable brand and if it's cheap, probably even worse. U may have screen burn from leaving a games console on while plugged into the tv, even if its not showing the game, it will burn it onto the screen. :(

Very dark picture

Hi there!
Depending on the age of the TV, it might be power supply related. Check Mains smoothing cap or others in the area. Video circuit is also a possibility. Tube would be the last option to look into depending on the age of the set, Good luck,JUS004

Blotchy picture

I get this too with my Samsung. Are you watching HD content or standard (cable, satellite) tv? If it's the latter, that's why. The lack of quality really shows on analog signals. The shows that I Tivo look horrible a lot of times. Another thing is the connection to the television. If you are using standard RCA connectors, try switching to either component or HDMI.

Hope this helps.

Faint horizontal lines in picture

This is usually caused by a problem in the Horizontal Output section, around the Horizontal Output transformer usually a capacitor or diode going or gone faulty... the line you see are the Horizontal "Retrace" lines that are useually "Hidden" when the circuit is OK..

The picture is dark

Hi This could be one of three possibilities, one the High Voltage Screen Adjustment is off, Two the Picture Tube is Weak, or Three there is a problem with the Video Drive Amp/Amps, these are things that should be checked or adjusted by a qualified technician, especially the High Voltage Screen Adjustment, hope this helps.

Try # 2... Green Fog

The green gun in your picture tube is set a little too high. If you are experienced in removing the back cover of TV's,etc., you may try to find the drive and/or bias controls either on the circuit board that plugs on to the neck of the picture tube or mounted on the main circuit board of your TV. These controls are usually labeled. If you can find them, locate the green bias or drive control and back it down a little while watching the picture through a mirror. A slight adjustment may correct your problem.tJIS IS CALLED GRAY SCALE ADJUSTMENT. BE CAREFUL THERE ARE SOME HIGH VOLTAGE CIRCUITS NEARBY. WORK WITH ONE HAND AND USE AN INSULATED TOOL TO MAKE ADJUSTMENTS I hope this may help you.AGAIN BE CAREFUL!! Stargazer

TV works fine for about 1hour.....then the picture

You have a problem in the Hi voltage or horizontal drive circuit most likly. Its a slight possiblity that the video is going out because of a cold solder connection from the flyback transformer blanking pulse to the video/sync separator circuit as it does and has happened in the past. This set should only be serviced by a trained service person as there are no real user serviceable parts inside this set. Good Luck
