Question about Televison & Video
We recently purchased the toshiba big screen at an estate sale it has bee working great until a few days ago-while on it will all of a sudden have the blue haze, when i go to the test portion to align the colors the HB (horizontal blue line) line is below the main line and it won't roll up --after a few minutes of having the tv off and then back on we can adjust it accordingly but lately it has been getting worse we had to have the tv off for almost an hour before we could adjust the HB--it will adjust once the HB line is above the center line if it is below the center line it won't scroll up when we try what can we do to fix it? THANKS!

Your TV most likely a convergence failure. ( common problem )
Here are some of the most common symptoms and example photos of a convergence problem
Here is a quick test....
Using your original remote go-to the tv settings then goto the convergence section.
Try to adjust the red and then the blue convergence.
You should be able to move them up, down, left, and right.
If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.
You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.
