Very dim display..so dark that all I see is a faint picture. Are bad capacitors to blame?

In regards to the capacitors on the board...mine are somewhat raised and there is a white rubberry substance around them. The bad capacitors might be causing the dim display? When I turn it on the screen is so dark that all I can see is a faint object because it is so dark. Are the bad caps causing this?

I would say either the video cable has disconneted, causeing the led that lights the screen up to not function,, simpley take the bezel around the screen, take the small screws aroud the screen to slightley pull the screen away from the back top to see if the cable is, or has pulled loose...If now the screen is bad..

Samsung Smart TV has a very dim picture. Is a LED driver board the proper fix?

Depends on the model. Have you checked the backlight, (LED in this set perhaps).

If your LCD TV or monitor has stopped working, or is displaying one of the following
symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can
examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life
of your monitor or TV by several years.
Take it to a repair shop.

No picture

Sounds like you have a backlight problem. To verify this, turn on the set, dim the lights in the room, and shine a bright flashlight on the screen. If you see a faint picture you have a backlight fault. It could be as simple as a bad capacitor in the power supply, or a faulty inverter board, or in rare cases a bad backlamp.

Will not come on, the lights come on but the screen is still black

This sounds like you have bad capacitors on the power supply board. Look for bulging capacitors. Any weak capacitors will have a bulge at the top. If you know how flourescent lighting works with a ballast, tv's work the same way to power up the backlights but use capacitors. The backlights when lit allows you to see the picture. If they are not charging up fully you get a black screen or a very dim screen which looks black under normal lighting conditions. Sometimes you can turn off all lights and maybe see a faint picture.

My Acer x193w monitor is powered ON but goes blank

Is the display going dark, but if you shine a light on the display you can still faintly see an image? If that's the case, the monitor's backilight is going off. That's frequently because of capacitors that fail. You can open the monitor and check them, replacing any that are visibly bad or below their marked value.

If the display is going blank meaning there's no image but the backlight is still on, capacitors might still be to blame, but the might be other electronic parts at fault. The problem might also be in the cable. A bad wire or bent pin making a poor contact can cause the monitor to go blank. Examine the cable carefully or try another one if it plugs in at the monitor.

If the trouble's not something obvious and relatively simple, like the bad capacitors or a faulty cable, it's usually more economical to replace the monitor than to try fixing it. It's often hard to find service information for troubleshooting, and monitors are quite inexpensive now.

Hope this helps. Thanks for using Fixya!

My monitor goes dim after a few minutes. When you switch it off and on again the dsplay is ok then becomes so dark

Hello,

How dim is dim? If the picture is still visible just like half as bright then your have backlight tube problem and unit LCD needs to be replaced, not worth repair price. If the picture goes out almost to a black screen where you can just bairly see a faint image then you hold the screen just right then you have a backlight inverter issue. If the problem is the inverter then you should be able to replace a few parts and get your unit back going. If you think you can open the unit up and maybe solder a few parts then I would open the case and look for bad capacitors on the power supply board. I can send you pictures of what to look for if you are interested. We also have a repair service for those units, most power issues run $15.00 plus shipping. Let me know if you need help opening the unit and checking parts.

42 inch LG Plasma TV - Lost picture

Most likely what happened is one of the capacitors went bad. When a capacitors goes bad it produces a popping sound. This could be an easy and cheap fix if you find the bad capacitor or capacitors. The bad capacitor will have a bulging top most likely on the power board but could be anywhere.

Clock display board

Replacing capacitor C3 on the clock board will correct the dimming problem. I will cost you about $2 for the part. Replacing the board does the same thing just with a higher price tag. Unfortunately, tt sounds like you may have a bad "new" board if this problem happened as soon as you put it in.

When I had the dim display problem with mine, the oven still heated up, chimed at temp, etc -- you just couldn't see the numbers. My wife didn't like it, so I fixed it. If your old board works like mine did even though the display is dark, you could try replacing the noted capacitor and see what happens.

I hope this helps.

flashing light Far right green light (button) flashes sometimes. Monitor takes a long time to come on and for the green light to stop flashing and be solid and monitor to stay ON. All connections seem to be secure. After it goes on auto-screen saver (i have it set to just go to black - no fancy screen saver), then when I move the mouse to have the monitor activate again, it takes like 5 minutes of jiggling all the cords, and pressing the green button on and off a few times for it to come back on. Also in the morning when I first turn on the computer the monitor doesn't come on. I know all the connections are correct, because I've had it connected this way for years with no problems - until now...
