SOURCE: 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.

This is for the 50" Vizio TV,

It sound like the control board has a problem. There is two way to fix this.

- Upgrade the firmware of the control board, If you can find the firmware upgrade device.
- Replace the control board (I think this the best solution)

I have a 55in Samsung Dlp the color looks good but a little dark can't see picture if the movie is dark


You might need a new bulb, the bulbs get dim as there life diminishes. Replace the bulb to get a bright picture. Do not use cheap bulbs, an OEM bulb for that tv should be $60+. . Cheap clone bulbs will work but will fail a lot sooner

Hello, My picture has gotten very dim and dark. I was told my bulbs need cleaning. How can I do this by myself or do I have to hire someone to do this for me. Thank you, Debbie


Its more likely that the CRT coolant needs replacement. Thats vert famous for that model. The CRT coolant gets messed up and the CRTs cant project the image properly so it gets a dull picture and the color tints are wrong.

Pioneer 52" projection TV, SD-533HDS,


It is likely that the CRT's (picture tubes or bulbs) are weak. It is a major job to change and all three should be changed to make the picture like new. However, it is not costwise to repair this old of a TV even if you can get the tubes. I estimate the cost of each tube is at least $200 each. I would call Pioneer and give them your model number and see if they are available. Only a trained technician should change the tubes because it requires a lot of time and setting up of the tubes and other things.

My samsuNg PS42A410C1D has no picture. i cant bring up any menus or anything see anything but it is producing sound


The most likely thing is that your screens backlight or inverter has gone faulty.
When you turn it on, you may be able to see a very very dark image of something (best seen by activating the TV menu). On some screens the picture is still far too dark to be visible though.
With this kind of fault, its down to fitting a new inverter, and if that doesn't cure it, then fitting a new backlight bulb (or bulbs) will sort it out, but these are not jobs that can be done without some expertise at them.
Most TV inverters are large circuit boards inside, and take about 20-30 minutes to change as the whole TV has to be dismantled, but the backlight bulbs are much more complicated (and extremely fragile too).
Unfortunately, there's not much else that can be done except trying changing those 2 parts. Although its possible for the screen cable inside to become disconnected and lose your picture, that results in the screen lighting up brightly (usually pure white if the cable comes off completely).

Dull / dark screen and picture quality not sharp


The cooling fluid in the blue and perhaps the green picture tube assembly has become contaminated. Only solution is to remove the assembly and dump old fluid and clean and reinstall new fluid.

TV has dark streak on one side of screen.


Your TV has a bad light tunnel. This part is inside the light engine. A qualified tech will have to replace it, but the part is available. Once it is replaced the TV will be as goog as new. Please take time to rate this solution and let me know if I can be of further assistance
