Tcon issue? Powers on Sony symbol shows on screen and backlight comes on. Goes black has image with a flashlight. Green power light stays on and red standby light is solid red no flashes. From what I have read it sounds like the Tcon is bad. Manual says if tcon doesn't process RGB signal then back lights won't power on. Looking for some input before I purchase any parts. Thanks

Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should trouble shoot. Contact any service technician. The circuit will differ with models and versions.
