PhilipsD16Dead apart from power on, Txt & RGB lights flashingIn prot mode - confirm by scope check of coll Tr7657 sm tr - 0v indicates in prot mode - normal when working = 5v; to check which area of set is causing fault monitor the following :- Audio - coll Tr7130; EW - cct anode D6502; LOP - coll Tr7495; FOP - emitter Tr7425. In a correctly working TV all these volts should be zero. In this case there was a high pulse at Tr7425 indicating a field fault; no field drive as L5251 was o/c removing supply to DPU2553 dig proc chip14-09-04
