We have an older Phillips Magnavox tv. The tv will turn on & we will see the picture for a short time but then the screen turns grey. We still have sound, just no picture. Also, the green power light...


Hello, the grey screen could be due to a missing 220Volt source which feeds the color (RBG cathodes)inside the CRT(picture tube). When this happens the beam current inside the CRT goes high in a matter of second, thus triggering the beam current protection circuit(blinking green light)shutting down the TV. Repairing the secondary voltage source is necessary to get the TV working normal, a good technician should be able to repair it for between 80 to 100 dollars parts included, except a picture tube, which could be also the cause of the problem(K-A shorts).

N64 Games Show Green-Grey Screen


Having a green/grey screen shows there is signs of life. I believe the power supply that's the problem. In my recent experience the following solution has helped me:

1.) Wiggle the power supply left & right two times. Now try and see if the Nintendo 64 works.

2.) If not, then disconnect and reconnect the power supply and wiggle the power supply left & right twice. Again, try and see if it works.

I hope it works for you!
