How do i fix a proscan tv to turn, only a red and blue light are on


Well without actually opening it up and determining where the problem is, it's unlikely you will get it to come back on. I suspect something wrong with the power supply but it could be something else also.

Turns on for 30 sec then goes bright blue and goes back into standby. turn back on it does it agian


This is blue CRT problem in tv as it is rear projection tv that has three CRTs red-green-blue inside to project color picture on front screen.
Blue CRT (tube) will be replaced to fix the issue and it is job of Pro because lots of adjustments are required after replacement of tube.
Local tv repair shop will help you for that.
Thanks

My tv screen wont turn on,it makes a sound fromthe back that sounds like it's going to turn on but it dose not.And it blinks a red light were it says stand by more than two times.


2 time standby light blink is an error code that shows problem section in TV.
Model number and brand name of TV would help to understand that error code.
