hi

im trying to save tv from trash

tv powers on with backlight ok.. sound ok

no picture

i test voltages coming from PS all seem ok..i have 3.3v 5v and 12v

i test fuse on tcon and is ok

i have 0 volts at the tcon board fuse though

so i imagine this is a main board issue?

thanks

Re: Samsung UN32EH5300 BL on no picture

In the tcon you have two LEDs, one that indicates that it is receiving 12v, the other led usually more to the right indicates that it is on, with a bridge between the pins of the two ends where the two flex cables that go to the panel are connected. you can make it work i send you images.

THAT WAY YOU CAN SINGLE A CABLE FROM ONE SIDE OF THE LCD PANEL AND ALTERNATE

The bridge goes between the first pin of the right connector and the last pin of the left connector
