when a televison becomes blurry and out of focus does that mean its going out or can the settings be adjusted?

Question

the televison in question is a 55 inch Daewoo

its a 55 inch daewoo thats not even 3 yrs old

Answer 1

Assuming you mean a CRT television, both are true. The picture tube is aging. There are 2 things to do about that. One is to see if you can find someone with a picture tube rejuvenator. Let them "bap" it for you. The other is to go inside and adjust the focus control, and possibly the screen control. Both are located on the side of the flyback transformer. That is the one with the huge red wire going to what looks like a "suction cup" on the back of the picture tube. Be careful around that transformer as it produces 20kv+.

I was messing around on a friend's computer while she was sleeping. I noticed how blurry the screen was and that bothered me. So I disassembled her monitor and adjusted the focus setting on the flyback. She caught me as I was putting the monitor back together, but she remarked that she could see the picture much better.

I am not sure which 55" Daewoo you have, a projection television or a plasma screen. Either way, I'd consider taking it to the shop.

If you have a projection television, they are more difficult to adjust than a single CRT deal. It is probably a good idea to let a repair technician look at it. They contain 3 picture tubes and 3 flyback transformers. Now, is there any pattern to it becoming blurry? Like did you move it or jar it? On the blurryness, is it just on one color, or on all 3 (red, blue, and green)? I don't know if what I suggested earlier still applies. Being that young of a tv and being so expensive, I'd go for a professional opinion.

Answer 2

If the tv is 5-10 years old it is probably simply worm out. Generally a tv repair place can give you an estimate for around $20 as to whats wrong with it. If it is 5-10 years old, it's probably the tube which can generally be replaces for a small bit less then just getting anew tv... time to upgrade to hd!
