Panasonic TH-42PZ8BA fault

[netdent]

Need some help with this one, first panasonic I have opened up! it powers on as it should to steady green light screen lights grey, have measured 203volts to both sus boards and checked the psu fuses I'm stuck now, not tried to connect video to see if sound present due to no dvd spare to try but will need to find one, any help welcome

thanks Ronnie
