It sounds to be a panel fault. Contact any service technician, and make it sure. If you wish to get some screen-shots about faulty displays http://electronicshelponline.blogspot.com/ check this link. Pull up previous posts there, either by its left side bar, or view it in Timslide option.

Is it repairable, well, this question can be answered only after opening the back cover and evaluating the damage. From you side, please connect the TV to a different power outlet where other similar devices are working and see. Then try changing the input device to something that sure works. If it does not work even then, this may need attention by a qualified service technician.

tried to check first the power supply if no any sign of bulging electrolytic capacitor this was a common that we encountered trouble.

It sounds that, the memory IC to your TV has damaged. This IC can be located very near to main system control IC. A very small one, with 8 solder terminals. Even though it is very small, function of it while the TV works is great. The work is a semi-skilled one, and you must have some knowledge in electronics to proceed.

GOT A MODEL NUMBER?

Replaced any capacitors on the power board that have domed tops.

try checking the system for timer or sleep mode operation try to setting it off

Sound like the TV is in protection mode. This happens when a part goes bad inside. the TV turns OFF to protect the other parts from being damaged.
Most commonly it's a power supply related issue. A bad capacitor or transformer on the power supply board is to blame.
For a do-it-yourself fixer with electronic experience, a Service Manual is the best for trouble shooting the problem down to the bad part. Normally, you can find it over the internet for less than $20.
