Hello and sorry you're having problems. I may be able to help, but I need to ask for more info.
1) Does the set eventually shut down with the red light lit on the front?
2) When is the last time you replaced the lamp?
3) What board are you referring to- there's about a dozen in the set.

If you haven't changed the Lamp out recently, or have and used one of the $35-$40 Amazon lamps, then this is the cause of the problem without a doubt. Mits sets running with sound but no picture is a direct indicator that the lamp has gone out, and no reason to suspect any of the boards in the set unless you had some other problems prior. The solution here would be to purchase a high quality Philips or Osram lamp and replace it as the set is telling you the lamp is out. The link below is where you an purchase the lamp for your set:
