Had module 9-1674-2 replaced about a yr and 1/2 ago for the sam

Yes it is possible that the 'remanufactured' module has failed again.

It is always better to actually repair the module rather than replace
it with a 'rebuilt' one.

If they did not replace the hv splitter, it may be bad now and also
would have taken out the same module. It is also possible coolant
leaked onto a board or a picture tube has failed.

It is a Zenith RPTV and they are not known for the best reliability
from the later part of the 90's, especially right before Zenith's
bankruptcy avoiding buyout by LG electronics (Goldstar) in 1997 or 98.

Another problem is that LG pulled the plug on real Zenith HV
transformers, leaving customers with only Chinese garbage replacements
for the boards (which last months to 2 years max). I stopped doing
these several years ago because of the junk transformer replacements,
but started servicing them again using Diemen (Spain) replacements,
which run much cooler and have been trouble free up till now.

It is unlikely that you will be able to actually repair and align the
set unless you have the training and service information available and
in hand. If you want an idea of the cost of any repair parts, any
Zenith parts supplier online can give you a rough idea of the parts
prices so you can be educated when looking at any estimate for repair.

You will have to first troubleshoot and determine what is the actual
failure in the set, the root cause of the failure, and how many
additional parts were damaged from the failure. Once you have this
knowledge then you can research and order the replacement parts needed.

If the hv splitter does get replaced, then it does take some special
test equipment to properly readjust the set. It also requires a
special test generator to perform the adjustments when the
sweep/deflection module is replaced.

In any case you can find out the suggested retail prices for most
Zenith parts at tritronicsinc.com. Realize that there will be shipping
and most servicers do need to mark the parts up a little bit to cover
the overhead of doing business. Also realize that for most servicers,
it costs an average of $65 an hour just to keep a good field technician
on the road. This includes wages, vehicle costs, inventory on the
truck, insurance, taxes, etc. At a minimum the typical labor cost if
it can be repaired with only a couple of trips is around two to three
hours of cost to the servicer.

You might be able to get some help from Zenith customer service if you
used a Zenith authorized servicer and they purchased the rebuilt module
from Zenith. Even though the repair warranty on the part was likely 30
days, LG/Zenith sometimes does assist with a second repair in the
interest of good customer service. They might send that replacement
part to the servicer at no charge this time and you would pay for any
other parts and labor involved, helping with part of the repair cost.
You will need a copy of your receipt from purchase of the set and all
repair invoices since it was new to have any chance of assistance. The
worst that can happen is for them to say no, but you will not know if
you do not start calling.
