i have no picture but i have sound, hooked it up to the rca's to bypass the tuner card and still no picture but the sound works fine. Had module 9-1674-2 replaced about a yr and 1/2 ago for the same problem. Would it go out that fast again? Thanks for any help. Nate
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.

Can you tell me somewhere online that i could pick up the parts for the repair? Thanks
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.
