Had Sony KV-32XBR45 repaired - now missing features
It sounds like you may (not likely) have a different uPC in this set,
but this would be an unusual part to change for your problem description. Or they may have changed something in the service setup (more likely) for the feature type. Many parts of the setup software is very difficult for a tech who is not properly trained or very experienced with this type of model series. When changing anything that has to do with the firmware or uPC, if this is what he did, it is very important he used the exact origional type, and not put in something similiar. When working in the uPC area, the setup may have to be redone. This requires the proper test facilities, and knowledge base for the model type. This is why I tell people that they should normaly send their sets to the factory authorised service rep, if they are not sure about the standard service shop. These sets are very difficult to service and setup, and many of the problems are a challange for the most experienced techs. What the tech will need is the exact origional service manual for this series of set, and go through the setups for the options, and make sure that they are set right. Any components changed that deal with the firmware in the set must be verified to be correct. As for changing parts in the video path, this usualy has nothing to do with the pin or scan problems, unless you also had video problems as well. Since I did not diagnose the set, it would not be right for me to comment on any part of the required service performed. I would only be able to comment on probabilities of circumstances.

I had a Sony KV-32XBR45 (32" XBR) television that developed video problems (it was jittering and pulsating between hourglass and pincushion) and I recently had it fixed. Now that I have it back, I noticed that several features are missing such as (1) side-by-side picture (alternative to PIP...PIP still works tho), (2) Freeze picture doesn't function, (3) PIP has 2 size settings instead of 3, (4) The "Display" button on the remote just cycles between showing time/station and not showing time/station. It used to also cycle through showing closed caption and turning External Data Service on.(5)...lots of other little things. The repair shop indicated power supply problem and also damaged video drivers. Seemed reasonable. But, given the missing features, it sure seems to me there's in new logic board in the TV. So, my first question, is there video circuitry along with logic circuitry on one board in this TV? (In other words, is it reasonable that the logic board would have to be swapped to fix a video problem?) My second question is, does anyone recognize the feature differences? My repair shops appears to just have ordered a replacement board from some non-Sony source (who claims they shipped him the right parts). I'm trying to help the repair shop identify exactly which board they did get instead of what they should have gotten. Or....is this really the right board and somehow has old software flashed into it (or maybe even has a configuration setting set wrong that can be easily corrected)? Would appreciate any help anyone could offer. Regards. Vince |
