    Thanks for your suggestion. Our JVC is only 3 years old but reading of other people having the same problem as we are and taking a chance on getting it fixed and a maybe 50 percent success rate of it staying fixed, we have decided to shop around for a new TV. Life is too short to worry about it.

Hi,

Assuming the CRT is still OK, it could either be:
1. Screen Voltage is low;
2. G2 B+ is out (common problem is a mega ohm resistor open);
3. a resistor gone high (or open) in the DA converter of the controller IC circuitry.

Any of the above would require extensive knowledge of electronic circuitry and components, use of a DVM and a soldering iron. Perhaps your best bet may be to seek the services of a professional.

Pls likewise consider the age of the TV (if a couple of years) and/or the downtime and cost of repair,. it may be more practical to purchase a replacement unit.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Jvc 27'' TV is too dark


There are two small holes on the rear side through which you can adjust focus and screen. Use a flash light and locate the two adjustable slots inside the holes. This part carries high voltage. Do not use a metal screwdriver to adjust. Put the TV facing a mirror so you can see how it works. Do not turn more than 1/8th of a turn. The focus control makes picture sharp or fuzzy. Screen control could change brightness. While watching the picture in the mirror, slightly adjust the screen control. Do not turn too much. If it doesn't work, then call a JVC authorized repair center.

Picture getting dark


My jvc 27" tv was so dark I could hardly see any night scenes, even with the bright all the way on. If you push the sleep button, let go, then hold down the video and display (together), the service menu will come on. Scroll down to #7 (too dark) and adjust the brightness there. Works immediately. Good luck.

Brightness of picture


If you feel good about opening your set then you can try this: Look for the flyback (high voltage) transformer, with the thick red wire which goes to the top of the picture tube. There are 2 controls on the flyback transformer, focus (top) and screen (bottom)Turn the brightness and contrast all the way down and then increase the screen control until you see retrace lines, and then back it down until those lines just vanish. Return the brightness and contrast to normal and adjust the focus control, if necessary, for a nice sharp picture. Let me know if that brings your brightness back.
