Most likely a Y sustain module failure. Gateway does not make a set, so I would need a part number off of the board in order to give you an exact price of the part. Usually they're around $300.00

Main power problem-i guess


Could be many things related to power. Sounds to me like a short though with that tzack sound you describe. How deep are you looking to get here or just looking for a major board to replace?

I have gateway plasma tv srs bbc 50 " get verry hot in the exauste and in the sreen is it normal? think's


Yes,it's normal, a plasma uses a lot of power (over 300W) so it generates a lot of heat - especially the screen.Remember, plasma is an overheated gas so a large screen contains a very large amount of a very hot gas.

Gateway GTW-P42M102, first sparks, now flashing green lt. in back


The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
