Re: Magnavox 42mf437b/37 picture fades

I took the TV apart again and noticed a bulging capacitor on the board to the right of the power supply so I will try replacing that.

I will also check out the tab adjustment.

Thanks.

Thanks for your reply.

I can access the 123654 information using the remote.

The other two pictures show the menu screen fading out after hitting menu on the remote.

What is a tab? I squeezed the frame and it seemed to make the picture last a bit longer....

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...

Hello,

I am a high school teacher in Sacramento, California. I picked up an old LCD TV off of Craigs List to display student work in the hallway, but the picture fades out on start up. I replaced the capacitors with an online kit, but to no avail, so I am joining this forum in hopes of discovering a fix for the TV.
