Plasma and LCD TV sets are prone to having capacitors in the power supply section fail. This is the most likely cause for the probem you describe. When capacitors fail your will commonly see one or more of the following symptoms.
  • No video, Power light is on or blinking.
  • TV is making a clicking noise.
  • TV takes a while to come on
  • Screen is very dim or flickers.

Again, You can get a power supply repair kit with the parts, detailed instructions, and support from sites such as www.TvRepairKits.com . Or just click here to see more details on their kit.

Here are pictures of capacitors...Notice that the ones below look bloated. They have failed and will need to be repalced.

When turning it on, there are multiple vertical lines. After it warms up a few minutes, they slowly start dissappearing, and the screen becomes visable. What is it, and can it be ajusted?


It's not adjustable. An electrolytic capacitor went bad.
You have to use coldspray to find the fault.
When the set is warmed up you spray on electrolytic capacitor's ( one at a time ) until the fault is vissable again. When found you repeat this again until you are sure you have the correct capacitor.
Replace the bad capacitor and the set wil work fine again.

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.

Shaky/Unstable Picture


This is power supply issue, one or more of your filter capacitors either bursted and/Or over heats (this is why it becomes better when system cools down after turning it off for 1/2 hour..You have two choices.1. buy a replacement power supply may set you back a couple hundred dollars but it will be plug and play. 2nd you can replace these filter capacitors make sure the can handle 105 deg celsius not the 85 deg. celsius, if you know how to trace the bad ones and desolder and solder new ones on the power supply board, or hire a techinician to replace them for you. Good Luck...

The high voltage power supply for the plasma display has failed. It may or may not be on a separate board that could be replaced the owner. If you find a separate board, it may have its own fuse which you could check for continuity with an ohmmeter.
