If you promise not to touch the wrong thing, you can adjust the screen and focus knobs on the high-voltage transformer (what we call the flyback). Do you see the big red wire going to the CRT tube? That is the anode lead of the high voltage (around 25,000 volts). The thing that it goes to on the circuit board has 2 little knobs coming out the back of it. Try adjusting those (use a tool with insulated handle if you please) to increase the brightness and improve the focus. When the screen adjustment is all the way up and it is still too dark - then its time for a new TV.

Wega KDF-50WE655 has purple spots, support says wega engine bad

I have over 10 years experience in electronic tech support.

I know this isn't what you want to hear, but the problem you've described sounds like one of the circuit boards that control the picture quality needs to be replaced. The cost of the board would likely be in excess of $200. There are usually several boards in a TV like that that control the picture and when one goes, you can get anything from lines in the picture to poor picture quality from blurriness. The main question is do you want to spend $1000 to fix a used TV?

I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.

Please let me know if I can be of further assistance.

DSC-T7 Blurriness

Try this test: Mount the camera on a tripod or set it on a secure base and use the self timer to trip the shutter. Doing this will totally eliminate any possibility of camera shake causing blurriness. If the picture is still blurred then there might be a problem with the AF but if it isn't blurred then the problem is either camera shake OR subject movement (or both).
