Big screen TV corners of tv blue and red

Hi Brandon,
I am afraid that the dark spot in the screen is not repairable. Manage as long as you can or go for a new tv.

The same exact thing just happened to me. I was watching tv and it just turned off by itself and now it wont turn back on. I've also only had mine a little over a year. The red light is on at the bottom left hand corner, but it wont turn on at all. Hopefully we can find an answer to what is going on!

A CRT (picture tube) for an RCA projection TV will cost $300-400 If the TV is more than 4-5 years old, you'll likely have to replace all 3 CRTs to obtain a watchable picture. Its probably not a good idea to spend that kind of money on a "free" TV.

your tv is under convergence problem usually we need to replace 2 big integrated circuits in the convergence section, at this point you may need a good tech to come over to your home

You have 2 distinct problems that should be addressed separately. Please repost the Samsung problem. I will address the Sony problem here.

If the "shadow" makes the picture seem somewhat of a 3D one, the problem is with the convergence circuit. This could be as simple as bad connections on the pins of the convergence ICs or defective ICs. If you can solder and would like to attempt the repair, update this and I'll provide more details and instructions.

you need new picture tubes, they are expensive, big screen tv life is about 10 years

Good Day;
It sounds like the TV may have a shorted CRT, picture tube, but let's trouble shoot:
1. Unplug TV from wall.
2. Remove speaker grill, two on bottom, the screws are covered with plastic caps, right and left side on bottom next to floor.
3. Remove inner panel.
4. The blue tube is the one the right side, remove socket, with phillips driver, make sure it's not touching anything.
5. Plug and turn TV back on, if picture appears with no blue it's the tube.
6. If still shuts down, bad blue CRT driver IC.
CAUTION: Call a factory authorized service dealer to give you an estimate, if this sounds too hard.
Good Luck, Day, Big Irish.

tv has double image color red and a curl line on left upper corner also sometime in middle of tv it has line

Hi: We had this problem under warranty, and tech installed the following to solve it: Parts BN96-02033A, BN96-02034A and BN96-02216A. This solved the problem for 2 years. I now have the upper half going black now and then for 2 to 3 seconds. I am ordering these parts from www.partstore.com and will just plug them in. Better than a new tv.

remove any big speakers that are close to the tv
