Re: E470VA no display, only backlight

I'm thinking it's prob the pc board? The backlight works, but I have no input showing up on the tv so I can't tell what input im on to check and see if I've got audio. The pc board it's in the center of my tv, with 2 ribbons going around the ToP and to the front of the tv. I looked for any signs of bulged or burnt capacitors. Everything looks normal. I checked all the wires coming of the main board going to the pc board, all voltage checks out with what the board says it should be. Anyone know where I can get a FSM for this model tv? I've still got my book but it s just the user manual amd doesn't have a electrical diagram. Any help appreciated.

Oh and it has been turning off and then back on sometimes 2-3 times a day for several years. Sometimes it won't do it for days. Doesnt matter how long it's been on, hot -cold, I've not been able to see a pattern other than just before it does it, The tv would studder about 5 seconds, freeze, and shutoff for 3-5 seconds then back on. But if you change the channel wjen you hear it start to studder, then change it back, it wouldnt shut off at all. Been doing this since probably 6 months after we got it.
