I need to replace the small power supply board in the tv, as my boat was hit with a large wave on the ocean , and the power board shifted in side the tv and shorted out one of the transisters against the metal frame supporting the display
First of all did the set get wet? If so, It needs the boards washed Immediately! Spray boards with windex soak em up. Need to remove all salt deposits and minerals or the boards traces will rot.Then rinse with distilled water let dry Then you could save this set. check this site They rebuild assorted stuff cheap. www.irionstvshop.com

I'm guessing you meant to say 'power off''. Otherwise it sounds like you have reasonably guessed there may be an electronic malfunction -- but with this, as with any device with a 'chip', I'd suggest first literally 'pulling the plug,' or if it's surge protected powering that down. Give it 30 seconds or so, then power back up. Best of luck!
1. Take remote control far away from tv - 3rd or fourth room. Then switch on tv. If uncontrollable scrolling stops , then cause may be remote button (Ch+ or Ch-) has got dirt inside and its shorting.
2. If taking remote far away doesn't stop scrolling then (Ch+ or Ch-) button on front pannel has shorted. Take a cutter plier and care fully remove button from its circuit board. ( If you know desoldering, it is far better than cutting). If scrolling stops then you can operate channel change with remote.
first of all did you buy a video amp . when you install multi screens you need it to get a good signal .
what is the car you installed the tv in ......
sometimes you can get your alternator interfering with your video some people install a filter on the power side of the alternator to help the signal with the audio and video in the car. can try putting a filter also on the power source to the tv 20 or 30 amp inline filter migt solve you problem. where did you ground your screens did you use the same grounding spots or did you ground them at 2 different places.... cause you can have a noise ground or creat a ground loop by not grounding them all together .
here are some pics of inline power filters ans80 by pac and ns50 or the ones to use . try some of these solutions and see what happens and get back to me email@example.com
Nothing really special needed unless you get it running and you have lines or snow on the screen. You can use a the PS2's A/V cable, just run it on the opposite side of the car from the power. Also, you will probably need more length than the average PS2 A/V cable has, so Splice in some length. As far as mounting, Most of the time, I fashion an adapter to connect into the bracing for the dome lamp. You might get lucky and find a Bracket made for the Expedition. If you do not like the postition of the Dome lamp, thge roof of the expedition should have ribs. You can make some cross beams to span betweent he Ribs and allow for mounting your Monitor.
