Thanks to the many of you who sent help my way. I found VD551 shorted. BYM26D is the number on it which shows this to be an avalanche diode. I used a ECG577 and set works fine, but I don't want to leave this diode in here. Does anyone know an NTE sub that would work? I can't find the NAP number 9338 185 10113 at any distributors. Thank you.

Unfortunately, even in PDF, these things are hard to follow. This set is dead...Only voltages I find are 152vdc on C of HOT. and 9.6 in primary of SMPS transformer. No voltages on secondary. Also, no 5vdc standby can be found. I can not find a HOT on this unit. I find two large transistors on heat sinks, neither of which measure shorted out of circuit. 2SD2102 is the one with the Coll going to IHVT, but I think this is a Darlington transistor. 2SD4423 is the other one on primary of SMPS transformer with 152 v on COLL. I checked all part on the primary and find nothing shorted. I tried to place a light bulb in place of fuse and Coll of the transformer on power supply and still dead. Can anyone who has worked on these give me a boost in the right direction? Thank you.
