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" filetypedf

.... 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.

I suggest that the OP saves the "View as HTML" version of the service
manual (the PDF link is dead) before it expires from Google's cache.

The Best Buy parts site suggested that other models using the same FBT
as the Insignia NS-19RTR are the Funai 6720FDG and the Funai
MWC20T6/TV.
