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.

Hi,
6 times blink shows problem with back light inverter board.
TV requires back light inverter board replacement. If you have electronics repair experience and want to repair TV by yourself, let me know to guide you part purchase.

If this were just about any other brand, you'd likely be able to find another brand of TV with the same size screen and swap the inverter boards and the LVDS board. The problem with Sony is that the company uses internal designations. If you have homeowner's or renter's insurance, it might cover some of the cost. Otherwise, put the damaged set on eBay (you'll get a couple hundred dollars plus shipping) and go buy a new set. Likely, any larger set for sale with a good screen is going to go for more on eBay and finding one is rare.

My first question is what makes you think the inverter board is bad? Have you tested the voltages going into it, are they all correct, do you have your voltages that turn the backlights on?
