Hi Group, Have a SMPS problem with this set, particularly with the HV switch in the power supply that seems to be causing the set to randomly pop - pic and sound. The numbers are ST (the manufacturer) 1136-1 but it doesn't cross using any variations of that identifier. Ran it on NTE search site using the *1136-1 which came back 121-1136-1 and that crossed with an NTE 2310 but I'm not real certain this is precisely what I need and I have no schematics. The original part is on the Zenith module 9-604-4 at pos#D3504. Does anyone out there, more experienced with the Zenith, have any information and could help?
