Question about JVC GM-P420UG 42 in. Plasma Television
Im having trouble getting any Video signal on input A input B and componant. RGB 1 has video signal from my Digital set top box but i cant connect my cabble tv to any othe input. I get a green screen on all three video input.
The problem is with the micro processor on the back of the fx-1169a board (gm-p420ug) this is the board the inputs connect to . yours may be a diffrent p/n due to yours bein a "e" extention model. to repair this problem you need to remove the processor from the socket, remove the socket from the board and solder the processor onto the board. the processor is ic002 on the back side the problem is thermal in nature due to cold solder joints on the socket. i have fixed this problem many times by using this method.

Hi don't have the solution for this issue but i'm experiencing exactly the same problem with my JVC GM-P420E : Green screen with all kind of input, the problem is intermittent, it appears more or less after 1/2 hour from switch on .It seems to be related to the thermal conditions ... any help or suggestion is welcome - ottavio

This is card problem, you need to replace the card- FX 1170 A. Apparently I have been told that it's worth $1000. Please check. Harish
