Just wondering if anyone has worked on a Hitachi plasma 50PD960DTA before. I've got one in for repair it has sound but no pix. From the powersupply the VS VA and 5+ are missing. I've since replaced the powersupply this hasn't changed the fault. I've also disconnected the supply line to the ysus and zsus boards still no output. If anyone has seen this fault before can you point me in the right direction please.

thanks from Mich.
