After a while, the image goes away, but you can still hear the sound. Tried switching from tv to video1 and video2 with no success. Only way to get the image back is to turn the tv off and back on. Any ideas?

Re: Image goes off
This is a sign that either the video drives to the CRT are not working or the anode voltage of the CRT has deminished. The vidoe drives dropping would be a problem in the video output section of the TV, and the anode voltage would be a sign of a problem in the High voltage output section of the TV. If you do not have a background in electronics I would suggest that you take the set to a shop for repairs.

It sounds like you are not getting a signal from your antenna connection. Check the cable & connector which goes into the back aerial connection of the TV. It will switch off after 5 minutes because it is not receiving a signal & if you are getting the menu box then the TV is working ok.
I had exactly the same problem When the TV was switched on all I could
see was a flashing green light. After cheching the TV internals and not
seeing a problem including the power supply unit which looked and
checked normal. Here is what I did to get M TV working again.
Disconnect it from the power supply. Hold down all the buttons
simultaneously i.e. the on/off, the volume, the programme, menu
buttons, all of them simultaneously and Plug it into the power supply
Lo and behold My TV jumped back into life after an absence of about 4 weeks.
Try it yourself exactly as above.
look if you have a DVD or VCR use its receiver!
so plug your antenna into the eg:DVD/VCR then connect its audio outs(red)(white) to the tv's (AV)in area. then plug its image out (yellow) to the tv AV in. then switch the tv on, flip ova to AV then tune the VCR/DVD and volla, sound :)
this is a blown or damaged transistor(FET)(MOSFET) but is easy to fix if you want to, however it will not undermine the rest of the TV as fas as performance or life expectancy goes.
The sound can be called screaming from the power supply,it senses a short and creates a frequency you can hear,the set has a problem and it needs to be repaired,I will check the horizontal out put transistor for a short,sometimes it goes bad without a reason and sometimes the high voltage transformer is also bad and both have to be replaced but first the transistor only if it goes bad again then you replaced the transformer too.Seek assistance from a servicer if you are not too familiar with tv service,it can be dangerous.
