GOODMANS LD3250HD

[EVILMRB]

Hi just got this model and what it does is sometimes it will come on fine then other times it wont
you just get a red light and when you press the remote or the buttons on the top,the red light will just flash.when the tv wants to work the red light will flash red 3 times and then go to green.
does anyone have a idea for this model bacause i have been told it may be the micro controller board

thanks in advance
