sounds like a power regulator problem, a horizontal drive problem,or the horizontal output is shorted because of a bad flyback transformer. If your not a technician there are no user serviceable parts inside these sets and i would advise you to take the set to a pro and have it diagnosed as you could get seriously killed fooling around inside of a tv set. God Luck

If the light goes out you definitely have a short somewhere. If it blinks you have a fault, probably in the High Voltage circuit. Most common problem is a shorted Horizontal Output Transistor. Unless you are an experienced technician you probably need to have a reputable repair facility look at this one. Most will give you an estimate for free or for a small fee which will be deducted if you decide to have them fix it.

I don't like combo units of any size or kind or make. They are all troublesome and they are all difficult to diagnose and they are all very expensive to repair. Please do not buy another one. You are always better off purchasing separate units; you will get better quality AND the total cost will be less for comparable units. The vcr used in combos is inferior and the tv is overheated because of the extra electronics in the box. So, please stay away from then.
Now, to your problem. The reason is shuts off is the protection circuit that is detecting too much current being drawn from somewhere inside the tv. Probably, the trip level of the protection circuit was set too close the limit at the factory and you really should have taken it back while it was in warranty. Now, due to some aging or component failure it is drawing more current and trips the protection every time.
I would judge the repairs to be quite expensive, relative to the cost of the unit. This is because techs don't like to work on them and they are harder to get inside and probe around to do the diagnostics. So, you are probably looking at a repair bill of $100 plus or minus.
Now, here is the really bad news. YOu can buy a pretty good 13 inch set for $49 and up. You can buy a pretty good vcr for $35 and up. So, you can probably get some good merchandise (at least compared to the 13 inch combo you now have) for less than the repair bill.
However, don't take my word for it and call a couple of shops and ask them to give you some estimate or guesstimate over the phone and whether it is worth fixing. It won't cost anything and you might get lucky by finding some shop that is hurting for business and wants to fix it just to make a few dollars on it. But, normal cost would be a couple of hours of labor and parts, so $75 minimum would be my strongest opinion.
So, your decision may be an economic one rather than a technical one at this stage.

Hold down the tamper proof button on your remote for up to ten
seconds, until the tamper proof light will blink and light
will go off. This will turn off the Tamper Proof button.
Let me know how it goes.
