Re: Wavy lines

This TV uses small voltage regulators. On each side of the regulators is the input voltage and the regulated output voltage on the other side. There are capacitors used for stabilization on the input and output. Change these capacitors.

There is a large metal case behind the input board in the back of the set called the hyper board that needs to be replaced.Good Luck

this is very common with these sets. the fix is to replace 11 very very smal capacitor on what is known as the hypermodule. The ideal sitation is to replace the hypermodule. if you can find it. I can do this repair. I have done about 10 at the shop. if you need to i would suggest finding someone who is very experence in surface mounted repair

My samsung projection tv has blue wavy lines on top of screen, I adjusted convergence, the blue will not line up horizontally, is there a inexpensive solution?

It means one of the chips has a bad section inside it, both chips and maybe a resistor near them will have to be replaced, involves soldering as each has about 18 pins soldered in

Check with who sells some kits for this by brand and model number

The wavy when cold is a issue with a board in the set--Hyper board--the warmup until it begins to work will gradually get longer and longer.

The blue: look at set on a unused video input--if see faint curved blue lines with some blue visable on the screen the blue screen control needs to be adjusted just slightly down until the blue and curved lines are not seen.

You need to take your tv in and have the picture deflector re-aligned.  This doesn't cost much, My dad had to do that to his a few months ago and it cost 30 bucks.
