Question about Televison & Video
My Simrad CA42 was working ok but has "Died" and will not power up again. I have checked the fuses in the power supply and the single fuse on the circuit board and all are ok. Power is reaching the circuit board via the lead. I have tried a master re-ser to no avail. The keys initially light for two seconds and then go out and there is no keypad tone. The screen remains completely blank although when the power is removed a slight response is seen. Does anyone have any idea's?

I have the same issue with my LG 42PC3DVA and I narrowed it down to the Y SUS board. After a little research there are a few items that are prone to go. The ceramic fuses (as you found), sometimes the capacitors on the Y SUS, Z SUS, and power supply go along with them You can tell because thy will be bulged at the top instead of flat. I replaced a few of my capacitors - they are only $0.89 each so it was MUCH cheaper than a board.
The other thing that is common on the Y SUS in particular are the FETs (also called MOSFET). They can be replaced if you are good with a soldering gun but they are static sensitive so be grounded. They are also a bit tricky to test so you may want to do some research on how to determine if this is the issue... or you can just replace the whole board.

do not change fuse if blown as there must be othere issues with power board and you could damage more boards check capacitors for leaks thanks gary
