Hello,
I recently purchased a used Magnavox 42mf437b/37 to display student work in the hallway. The only hitch was that it had to be turned on/off several times before the picture would stay on.
Now the picture fades almost immediately no matter how many times the power is cycled.
I replaced the capacitors and two diodes on the power board. After a couple of on/off cycles, the picture remained. Then after about half an hour, I moved the TV, and I'm back to having the picture fade almost immediately.
I can access the 123654 menu from the remote and the other smaller menus, but the main menu fades quickly so I can't access the factory reset mode.
Also, there is a speaker wire attached to the power switch assembly that connects to nothing. One wire is soldered in and the other is under an attachment screw.
From the back of the TV, even though the picture has faded, there is a bright white light showing through a couple of openings in the back panel.
Any help would be appreciated.
