The KV-27FS100 has a BA-5D chassis, the KV-27FS100L has a BA-6 chassis. The BA-5D chassis seems to be the older generation, but appears in sets 27-36in. The BA-6 chassis has fewer boards, and is in sets 20-27in.
Excellent post, Gene. What were your original values for Bcut, Bdrv, Gcut, Gdrv? Did you make the changes only for Video4 (component) or also for the other inputs - tuner and vid1- vid3? I am wondering if there was much difference in the TV tuner input. Any consistent improvement in skin tones on network TV? How do you measure the red push with Avia? could you have used it without the calibration equipment to improve the colour balance once you knew which values to adjust?

All looks OK. Some items from the first 10 (down to SBRT) are different than mine, but I think these are factory adjusted for each set. If the picture looks OK, then don't worry. [ This message was edited by: KirkB on 2004-03-02 20:37 ]
These values likely will vary from set to set to account for each picture tube, so your lost settings were likely different. Something you might try - when in service menu on the VP1 section - switch TV/Video to check the video1-4 inputs. Some of the data items in here have a different value for each input. Your original values might still be set there on a different input. When I got my set, SBRT was set lower in video4, and I could change the value just for that input. The *CUT and *DRV values are the same for each input on my set.
Mine are set at RDRV=64 GDRV=43 BDRV=58 RCUT=120 (that seems high but that's what it is) GCUT=67 BCUT=62 Here is a link to generic service menu info with some setup instructions http://myweb.accessus.net/~090/sonyadj.html#list a google search for servicemanuallite will get you excerpts from an older manual with more info. Hope that makes Homer more lifelike.
Tim, Yes, the service menu for the L model has many items not listed in the older service manuals I have seen on the Net. I have noticed items 3-8 in the RGB section (CORL, CORH, COGL, COGH, COBL, COBH) - they look like they might be color decoder values for r,g,b - they might help adjust colour balance. Are the descriptions in the service manual helpful?
Here is a link to part of a service manual in pdf format for an older model sony set. brian.vallelunga.com/sony/ServiceManualLite.pdf It will give you instructions for the basic adjustments, although the item abbreviations and values may be different for your model. It will help you decide if you want to buy one for your model? Would the cost of a service call be comparable to the cost of a service manual?
Robby, what settings did you change to fix the 'red push'? What were the original and changed values? I have a kv27fs100l, and have tinkered in the service menu. I have found some other service manuals not the one for the 100L - and read that to adjust the RDRV and RCUT you should be measuring voltages with test equipment with different test patterns. Use these red gun adjustments to adjust overall dark and bright levels. The BDRV, BCUT, GDRV and GCUT will change the white or colour balance for dark and bright picture settings. I played with these a bit while watching ..
