Had timer on nite before. In morning, tv would not turn on, no sound,and no picture.
Sanyo TVs usually only have two boards in them , doing a
visual inspection of the power supply capacitors usually reveals swollen
or bulging capacitors.
If the capacitors look good, voltage checks would be needed to isolate the problem to either the main board or power supply. Check for 5 volts to the IR board (& or keyboard) , if five volts is present suspect the main board

I had the same problem and my tv was out of warranty. I took it to a local repair shop and they told me didn't work on that brand. They said they charge $300 minimum for labor, plus parts. So probably at least $500 to fix. Since I figured we had nothing to lose my buddy and I took it to our shop at work and decided to take it apart and look for any obvious problems such as blown fuses, burned components, etc. All of the printed circuit boards are connected to what appears to be similar to a motherboard via data
ribbons. We disconnected the data ribbon of each PCB to the microprocessor PCB and turned on the TV. Each time it turned back off after about 3 seconds. When we disconnected the Y-Main PCB the TV stayed on and I got the sound back, but no picture. We then disconnected the buffer PCB's from the Y-Main to ensure they were not the problem. Finally, we pulled the fuse on the Y-Main PCB and reconnected the data ribbon and the TV and sound stayed on again. I found a site that sells the Y-Main for $179 and I am deciding whether to try it or not. Any suggestions or comments would be helpful.

hiiiiiii here shivam
i want to tell you that that same problem is occuring my computer but now it is fixed
but your problem is of tv don't worry is this is help full to you--
this problem is common on this model. your vertical output circuit has gone bad. but i am sorry to say that a repair cost is to much for a tv this age. a cost would range 100-150. i say invest this into a newer tv. this model was good for 10-12 years and you have got better than that.
good luck :)
let me know if you need more info?

Probably out of warranty?
this is an issue with either one of two things,
1) Power supply
2) Lamp 'Florecent back lighting tubes' ballest.
Depending on the service shop rates, the labor is more than the part. Call around and get some price quotes. Worth your time. These set's are still expensive?
Now if it's a 15" . Buy a new one. They are just a throw away item these days.
