First you need to check if your set is in the cable mode and not antena mode,if the set is in cable make sure is in the standard cable mode and not another type of cable like HRC,if it is change it and try the autoprogram to set the available channels.I hope it helps.

Have you checked the fuse in your plug. If the fuse has blown it won't work in any wall socket. Change the fuse for a new one anyway, then try again.

This is a very common problem. Theres a guy on ebay that will fix it for you for 24 bucks plus 5 bucks shipping. When you open the monitor, on the back panel there are 2 boards. One is a power supply board, the other is the interlogic board. The power supply board is where the problem is. I do not know the exact component that needs replacing as I did not test this yet. I do not have the proper test equipment. For 24 bucks, I'm just gonna let the ebay guy repair it. I will report my results here when I get the board back. I'm also gonna mark the components so I know what they replaced.

The power supply is shutting down for one reason or another. This unit has 4 shutdown alarms feeding the main processor. It doesn't take much to trip it and believe me, it's a ***** to find it if it is a subtle condition. The VCR could be shutting it down as well if it is not reset exactly right.
This is what I did with the one unit I worked on; It would shut down after 5 seconds. The picture was good when it breifly came on -- but it shut down anyway.
IC1601 is the shutdown opto isolator that will shut off the supply. I removed it and the set came on. After a few minutes one of the power supply diodes started smoking so I unplugged it. The diode, D1618 was bad so I replaced it and the TV worked. But, I could not put IC1601 back in without it still shutting down. I spent hours searching and couldn't find anything. Since it was my son's TV (which he found at the dump) it was OK by me. BUT, if you remove this IC, (it is a four pin located near the yellow transformer) the set will come on no matter what. Just remember, if there is a problem, it will show up quickly. Maybe a new troubleshooting method? Ohms law troubleshooting? No, unfortunately not. Just be careful and try to find the problem.
If you google this model number, you will find a free schematic that --someone-- uploaded to a free schematic website.
