Well, as a first post, here goes:
I recently bought a TX-T3093WH. I'm very impressed with it. I find it has a great picture, and I'm happy with CRT. When I purchased it, the unit came in SHOP mode. So, I went in to change it to HOME mode. Shortly thereafter, I saw some lines at the top of the screen. They were very fine, and after 10 min. of the unit being on, they would dissipate. Now, having been in the service menu before, I went in to see if there was anything I could do to fix it. FIRST MISTAKE: I did not write my settings down. I don't know why I didn't. I'm an audio semi-professional, and if I change a dial on an equalizer or change the gain on a preamp, I always make a note of it. For reasons unknown, I did not with the television. SECOND MISTAKE: I could not really make heads or tails from most of the abbreviations, but there was one called LINE CORRECTION. This seemed to be what I was looking for, and I adjusted it. It seemed to do nothing. So then I went back and found the DEFLECTION menu. I adjusted that...
After finding that I had seriously and negatively affected the geometry of my television, I decided to look here. Immediately I read the hundreds of warnings regarding writing your settings down, and that there is no factory reset, as each unit is unique. I read how adjusting the LINE CORRECTION was one of the worst things I could have done. I preceded to feel like an idiot for three days. I got online to read horror stories like mine. I looked at people's settings, and eventually decided that I should not mess with it more than I already have. I don't want to make it worse. So, I decided I will hold of on fixing it until I can get either a service manual (which I'm fully willing to pay for) or have a technician come to calibrate it.
So, does anyone know what I should ask about if calling a service place in regards to fixing the geometry problems on my screen? Does anyone know where I can obtain and/or purchase a service manual? (I did read in a previous post that these may not be available yet.) Last, but not least, is there any comprehensive guide to what the various options in the service menu actually do? I read the post regarding SONY SERVICE CODES, and found that to be rather helpful, although many of the abbreviations are different. I realize that some of this is repeated over and over again here. I just thought that if I never posted this, I would regret it. Furthermore, there may be something I don't know, and someone out there may know of something specific to the TX-T3093WH that could help me. Any help would be appreciated.
