My proscan did this. I took off the back. Spotted the buldged capacitor. Went to Fry's to find a replacement. They didn't have one but they referred me to someone down the street. Called, he had it. Cost like 2 bucks. Got a soldering kit for 15 bucks. Removed and replaced. And it's like brand new again! 4 years later, the main board is going out :/ that's not so cheap.

Sounds like your resolution on your computer is set too high for your tv to accept. Try putting your computer resolution down to 1024x768 or lower and see if that works.

adjust voltage G2 Screen. thats why have retrace line. resolder also CRT board.

There is no power coming from the step down transformer

From elsewhere on the web:

"Proscan used to be the RCA high-end trademark; RCA (at least the TVs) was purchased by Thomson; they leased the proscan name to a Korean outfit that has the TVs made in China.
I've never owned a Proscan (post RCA)... but the internet buzz is that they are of inferior quality and that it's virtually impossible to get support in the USA. I would qualify that: Costco is selling Proscan TVs; they extend the warranty by one year (to two years); and if you have a problem, ya got Costco behind you. So I guess unless you buy one at Costco, you should pass"

Perhaps you need to contact the entity at which you purchased the television.

I am sorry Sir, the display panel is bad. If you purchased it new, it should under factory's warranty. Please call Proscan for a warranty repair.
