I have not worked on your model of set, but have had similiar faults on other types.

I have had colour shifting from weak CRT's in projection sets.

In the video processor areas, I have also had electrolytic capacitors becoming thermo sensitive and becoming unstable.

Try using a heat gun and cooling spray (bottled liquid air for freezing) to check for thermo sensitive parts. Start by cooling and heating the capacitors in the various areas that deal with the video path.

One yellow, one pink, and one blue spots appeared on my tv screen.


The set if projection which model here is, has arced and now each of the three picture tubes used has a tiny permanent burn mark on its screen.

That is what you are seeing, the set uses three picture tubes with screens like the old tv sets===the coating has been burnt in each, want to prove it, remove rear cover and cover any one of the three lens and that mark on one tube will go a way.

Not fixable.

I am having LG scarlet 32". Problem is whenever I switch on TV, it shows picture for a second or two, after that there is a black out ,though sound still coming from tv. Problem persists even if I...


Hallo! This problem means that you have troblem with the high voltage invertor part, that alimentates the lamps inside the LCD. Usually you have to replace the high voltage impuls transformator on invertor board. Open the set and you will see two pairs of blue/white/pink/grey coloured wires. Near the connectors that wires go to the board must be the transformator. ON it must be written the model of it, search on ebay, buy and replace it.

No picture, but still displays light


Sounds like a dead screen you'll need to get it repaired. Check if it is still in warranty.
