mitsubishi vs50707 shuts down on start up with blink code.

[nel]

Hi I have a mitsubishi vs50707 which shuts down (2-3 sec) in protection mode, and blinks five times in sets of four. Prior to it starting to shut down the convergense went out .I have replaced the stk's 392-11o. I had the convergense fixed 2 times before by 2 different techs. The last one wanted to charge me 1200 to replace both boards(main and signal inside) due to age 2001. It did seesmoke from the right side of t.v before starting to shut down. Can anyone with any info about the codes or next step give a pointer. I really thank you for your time.

Did you check the pico fuses?

Sounds like you might have the problem I am having with coolant gel from the CRTs leaking onto the circuit board.

My 50707 just went to the shop after it would go into protection mode, worked over a weekend, and then totally died. My technician said that Misubishi may have overfilled the coolant gel in the CRTs when they were first made, and that the gel dripped right on a board where it caused problems. Mitsubishi is looking at my board now to see if it can be fixed. Not all the components on the boards are available anymore. The technician also said that Mitsubishi is recommending that non-flammable drop cloths be added in the cabinet so that any drips will hit the cloth and then be directed to drip off into the bottom of the cabinet where it won't do any damage.
