Well you did start out good, thats cool, now we have to define focus, Is ir blurry around the edges as well as the whole Picture? If it is, it could be the picture tube, A bad solder connection on the tube socket, and yes it could also be the flyback transformer.

My TV has gradualy developed a blurred picture over the last month and now is unwatchable, is it worth fixing. It is 8 years old


guessing this is a rear projection tv. You did not provide a model number. Check the CRT fluid to be sure it is clear and not cloudy. Since you mentioned the problem was gradual over time, I'm guessing it is the fluid. This would be more obvious if you were seeing like a frosted look to the picture or dark areas and bright areas, which are caused as the fluid clouds up.

Your alternative is to try adjusting the focus of each bulb on the focus block of the tv. I think with an older Philips the focus block is in the back of the tv.

BLURRED COLORS OUT OF FOCUS PICTURE , PICTURE LOOKS WASHED OUT DESPITE MANY SETTINGS THIS IS A LG325700 tv


This sounds like the High Voltage transformer may be going out or at least the focus control on the transformer needs to be adjusted.
