You have what sounds like a failing vertical output IC also could be some bad capacitors. If you are able to solder it would cost a few dollars to try this and see if it fixes it. If not you would need to replace the whole board itself and that could cost you a little bit more money. If you need a tech it is time to get rid of it you are looking at at least 200 dollars for repair.

Your TV is in the protection mode. First, locate the horizontal output transistor. This is found very close to, or next to, the horizontal output transformer (also known as the flyback). The flyback should be on an aluminum heat sink, or on the side of the metal chassis. Disconnect or unsolder two of the three legs of the transistor. Measure it with your meter, or plug in the set with the light bulb attached across the fuse.
If the transistor is shorted, or the light bulb doesn’t glow bright anymore, replace the transistor and plug back in. If the light bulb glows bright again, you must replace both the flyback and horizontal output transistor simultaneously. In some cases this will fix the set, but sometimes there are multiple problems with a set.
Go to where the flyback is, and start measuring the diodes and capacitors on the flyback itself. If you don't find any shorts there, it could be a shorted vertical output IC, a shorted sound IC, a shorted disc capacitor in the Hi Voltage/sweep circuit, or in rare cases, a shorted capacitor or tuner.Feel free to ask and post whatever the result of your troubleshooting..
Hope this may help;

I'd suspect one of the controls that would be overriden by analog direct is unknowingly activated. LOOK at the front panel and interpret every indicator for how it could cause silence. Refer to the manual for those you don't understand.
Any Tape Monitor activation would disable digital sources completely.
See page 14 for how Line Direct affects DSP modes.
