Television and Home Theater

i have a problem if anyone can help, so i called a tech out to check my tv, he wants to charge me 550.00 to fix it.

basically my tv started with a line about 3 to four inches in width on the left side running down, and it is grey about 3 or 4 months ago, now about 2 days ago, i turned it on and the image started freezing and it went out now its all different colors on screen and see image of channel in background, what can this be Help !!!!!!!!!!!!!

It is sooo hard to find reliable service!  I called 5 different repair centers and they all gave me vastly different advice and fee structures. 

I have the Samsung 50" DLP and am having the issue (well described on this site) where the picture keeps going out. 

 Does anyone have a recommendation for a reliable repair shop in San Diego area?????

Hi,

      I want to start by stating that I was trained years ago as a computer technician. I have discharged many CRTs in my day. I understand that the television holds a charge even when turned off and unplugged.

I have to remove the circuit board on my Mitsubishi VS-50502. I want to be sure I go about discharging the high voltage safely and correctly. I have not done this before on a rear projection television, but I assure you I will be very careful. I absolutely respect electricity - especially 35,000 volts!
