Sony KP-61XBR48 Service Menu Item Keeps Changing

I have a Sony KP-61XBR48 RPTV (4:3 standard NTSC model), purchased in 1996, that is still in good working order except for two recent problems. 1. One item in the service menu (not the user menu) sometimes changes its setting after the TV has been turned off for several hours. Specifically, the service menu item that changes is called "SPIX," which I believe controls the sub-picture (contrast) range available on the user menu. When I write the service menu change to the TV?s memory, sometimes SPIX will still change its value after the TV has been turned off for several hours. No other service menu items are changing settings on its own like SPIX is. 2. When I am in the service menu, the TV?s picture is different (color, hue, brightness, contrast, etc.) than when I am not in the service menu, making service menu calibration adjustments difficult. Does anybody have any ideas what could be causing these two problems and how to fix them? I appreciate any advice and suggestions you may have. Thank you.

The only thing to do is pick which video mode you want (tv, vid1,2,3,etc) and then turn off and then immediately on for an hour or two and then the picture will come on. I,ve heard it's an internal transformer problem.

I have a sony 51 " rptv. the on screen image arcs on top and bottom towards the middle of the screen he sel diagnostics showed 1 timw akb and 1 hv. the timer blight has been blinking 4 times then stops any...

4 times blink is error code for Vertical Deflection problem and you need to check +15 and -15 volt supplies on D board and IC8003 is suspected.
Needless to say, check above in case you have enough knowledge and experience of big TV repair as high voltage shock risk is involved.
Thank you.

TV wont turn on

2 blinks is Over voltage protection and 7 blinks is high voltage shutdown. You will need the service manual to even begin to diagnose this set with two codes. Let me know if you need me to post a link of where you can get the service manual.
