I have this LCD TV, and it's giving sound but no picture. Some seconds (maybe 15-20secs) after starting up I can see a quick flash of a picture, but it disappears, sound remains.
A quick google finds this:
I took the inverter board out (attached), and can see it has "Darfon V144" markings on it.
Is there any good way of testing the voltage transformers? Is it likely to be 1 or all of them faulty? Any other checks I should be making?
Thanks.
