SOURCE: No picture on a Westinghouse lcd tv model ltv-20v4

I had this problem with these tv`s. The problem actually lies with the power supply inside the unit. Some of the units i`ve seen have 2 blown capacitors on the power supply (C7 and C6) replacing these works. On others, the capacitors as well as a few transistors (Q8 - Q1) are blown. But on all the sets i have seen with this problem, changing the above components restores full functionality to the system.
