Hi guys i have a LCD42761F acoustic solutions tv had it off a family member when i turn it on it just gives me the blue standby light. I have checked the caps on the power board and all looks fine. I just cant pin point what the problem is.

Check the poly caps and the diodes i have circled in red.
What voltage do you get across the main cap ?

That's a vestel based unit, I had one in a technical model with main board fault that wasn't switching the psu on, never did narrow down the exact fault but replacement main cured it, be sure to check all psu voltages are coming up first though, there are schematics available online
