Hi and welcome to the site,

Initially, postback with the model number, something like KV-32XBR400.

Offhand, yes, on the XBR series, 7 blinks of the Standby/TIMER LED indicates that the Sony has kicked in auto-protect due to a fault in the horizontal section.

The model number would identify the chassis and a Service Manual with schematic diagram could possibly be available,

Good luck and thank you for asking.

Sony Model # XXXXX Thank you!
TV Technician: Louie, Technician replied 8 years ago
Appreciate the information.

If the 7 blinks is consistent and no other faults / blinks...

The Sony KV32HS510 uses the DA-4 chassis. The most likely fault would be in the D board which could be replaced as a whole and maybe inquired from Sony or here, P/N A1300319A.

If you are considering component level repair, first components to check in the D board would be:
  • Q8013 & 8014, both are IRFIB7N50A;
  • zener diodes D8012 to 8014;
  • resistor R8051, a 0.1Ω, R8058 & 8061, both 10Ω, R8047, 0.22Ω and R8070, 0.1Ω; and
  • IC8002, MCZ3001D.

If it would help, I could upload a pdf copy of the Service Manual to an offsite server.
