It's a 4-year-old Sony KV 27542, 27". I tried the various suggestions found by Google:
- PWR OFF, DISP, 5, VOL +, PWR ON
- PWR OFF, DISP, 5, PWR ON
- PWR OFF, hold "channel + -", while powering on
None of these gets me into the serviece menu.
There doesn't seem to be any recessed switch on the rear of the TV either.
Thanks for any help.
