Having browsed the user manual I wonder if you plugged in the Sony BDV T57 Home Theatre System while the Polaroid FLM-2632 tv was powered down via the optical cable .
Then powered up the Sony BDV T57 Home Theatre System first and then powered up the Polaroid FLM-2632 tv
Maybe the Polaroid FLM-2632 TV has to detect that the Sony BDV T57 Home Theatre System is connected and powered up when the Polaroid FLM-2632 powers up. To activate its digital audio out ????
The note part about only being available only under HDTV (cable/air) mode. Might be the cause of your hassle also ?

You could try pressing the source button on the remote to see if that brings it up.
Also the TV may have got itself in a muddle. There will be a way to reset it to factory setting. If you can get into the TV's setup menu there ought to be an option buried somewhere to do that.
Either one of two problems, the main power supply has an issue or has gone bad. 'Not supplying the correct voltages to your processing/controlling board' or that you are having problems with your processing/controlling board. My guess is the main power supply board. A Good TV Service Shop would give you an idea of what the cost of repair should be. Call around. Blessing, A/V Media Tech Guy
Three guns Red Blue and Green in the picture tube of an old CRT set. If one of the guns goes out it effects that color. Sounds like one of the guns inside of the tube is going out, To costly to replace for such an old antilog set that will have to have a convertor box next month anyway.
Sounds just like a loose solder connection. The trick is finding it. I would start with the microchips and the large transformer. Otherwise, it could be a capacitor starting to short out. I would give both options a 50-50 chance to be the problem.
Check all your connections if they are connected properly.if connections are good that means the tv is having problems in the color circuit call a tech to do repairs on your tv.good luck.
Try using your RCA imput to see how the picture looks compared to the tuner picture,is possible your tuner imput is bad,make sure the conector is not loose,the overall picture should look different but not fuzzy all over,using a dvd picture thru the aux (rca)imput should show you the difference.If the conector is loose only it could be repaired but if it is solid the tuner might be bad and it will need to be replaced along with any board it might be mounted to.Let us know how it goes or if you need more information.
