tv is 2 y/o it was intermittently shutting off for approx 2 weeks but would come back on right away. now it has gone off and will not come back on. the only sign of life now is the blue standby light. please help! i do have some technical skills but no knowledge of televisions so if someone could walk me through the repair i would appreciate it greatly. thanks for reading this. and happy holidays to all!

I have to hit the power button on the tv and simultaneously hit the volume up and down buttons furiously to get the tv to come on. This works about 60% of the time when i want it to. Sometimes the tv will turn off itself, but not usually. It has a great picture, i just don’t know if it’s worth getting it fixed. Anyone have any idea what it may be, could it be something simple like a short or loose wire?
