Insignia TV/VCR/DVD combo model NS-19RTR won't turn on

Hi,
I have an Insignia TV/VCR/DVD combo model NS-19RTR (mfg 05/06)
in my repair shop that won't turn on. Note: I do not have a SM. This set was
turned off during a storm but a storm related power surge damaged it.
The main fuse is good. Raw B+ is 171V (aok), the regulated B+ measured
+43V which doesn't change when pressing the Power button. I also found
a +5V source and that was ok. There was no visual sign of damage (eg. burnt
component) anywhere. I tested several parts such as diodes, etc.
Has anyone repaired this or a similar model that was damaged by a power
surge?
Thanks in advance, Brad
Here is a site offering spare parts for your device:
http://bestbuy.partsearch.com/GetMod...Number=NS19RTR
Typing "FBT" into the search box produces a part number of
LTF00CPXB048 for a "TRANS FBT JF0501-3201A-G".
FWIW, a Google search for LTF00CPXB048 then finds a Funai 6719DG
(Sylvania) 19" colour TV/VCR/DVD.
Searching for "vertical" in Best Buy's database produces
"QSBBA0SSY003" and "VERTICAL OUTPUT IC LA78040A".
A search with Google on ...
"QSBBA0SSY003" filetype
df
.... then finds ...

It may be that one or more of the above PDFs has a similar PSU
circuit. If not, then you could repeat the procedure for other major
ICs, eg the jungle IC.
