No you cannot replace an individual LED, it's simply too hard for yourself to do it. The led is a sheet of led diodes and to replace one is very difficult, requiring lots of soldering etc. You should get it to a repair shop where they have spare exchangeable panels which is easier to replace. Also the yellowish colour is probably due to the pixel itself being burnt, not the LED light.

    I would find the panel model of your monitor and google the same panel for maximum fixability. Yes, it's not your backlighting, it's your pixels being burnt slightly. Best way would be to send it to dell or a repair shop for repairs as they will have the correct panels. But if you want to DIY, you can purchase a panel online after you find the type of panel inside, I don't know which site you should get it from, but beware of scams!

SOURCE: Xerox XG-91D 19 in. Flat Panel LCD Monitor

Just tore mine apart so here is some help. You need to remove the two screws on the back of the case on the bottom. Then you remove the front cover it slides toward the top of the screen then lifts off. You can pry it off if that doesn't work. If you want to seperate the screen from the back cover you then need to remove the swivel mount and the other two screws from the back cover.

SOURCE: Monitor displaying yellow tint

Try this. Worked for me immediately, including with PhotoShop

  1. Go to Color Management (in Vista, just click the Windows Orb / Start Search & type in Color Management)
  2. On Devices, select your display (repeat if you have multiple ones... at least I did). e.g., Syncmaster ....
  3. Check the box: Use my settings for this device
  4. Select any and all profiles you have and Remove them.
Check to see if that fixed it. You may need to restart. I didn't have to.

SOURCE: My ViewsonicVP930b Monitor Suddenly Turns Off

This is a classic VP930 problem.

It is caused by bad capacitors in the power supply circuit.

Open the monitor, and look at the power board. There are six capacitors. Replace the 220uF @ 25V and the 1000uF @ 16V capacitors. I would recommend replacing them with 35V and 25V capacitors respectively.

If the serial number on your monitor starts with Q8H you could also have a bad IC on the main board. Q8 on the main board is an FET in an IC package. If this problem persists solder a wire from the right side to the left side. There is one pin that turns the IC on and off. All the other pins (per side) are soldered together. Do not solder the pin on the left side that is by itself. Just leave it. Solder ALL the other pins on the left to ALL the other pins on the right.

Remember, do this ONLY if the problem persists after replacing the capacitors AND if your serial number starts with Q8H.

My dell IN 2020 M monitor goes off after 4-5 min...i tried reducing brightness to zero ...it worked just for one day but now again the same problem starts....plz give some suggestions...


Dear Kumar, First of all make sure your laptop is not getting extra heat?
and most probably this issue is with your Graphic Chip.
you have to take it to any hardware export.

PS: Its recommended to visit Dell Authorised Service Center, otherwise this issue is much sensitive and will keep coming after few days even after the chip replacement.

Can you still see the spot when the TV is off? In any event, the screen may have something on it or the mirror that reflects the image from the projector where the bulb is. Make sure the projector bulbs are clean. Good luck, thanks for using FixYa.

Looking for replacement parts for vector spot light


The bulb you are looking for to fit these vector spot lights is an automotive bulb, and H3 with a PK22s base. They come with a cable and a nickle size disk at the base of the bulb. They come in several wattages, eg 55w and 100w. Try the "bulbs.com" website, in their search box type "H3 PK22s" and you will see they have a variety of wattages and voltages. Be sure you buy a 12V for these spot lights. They come with a cable and nickle size disk at the base of the bulb. Hope this helps. From Uncle Ray
