SOURCE: I have a panasonic flat panel tv 1080i. 46

the s1 models have been having several problems. it really depends on how many times the red led is blinking. panasonic uses a certain number of blinks to tell you what board has failed. the s1 models have just recently come out. therefore your tv should still be under manufacturer warranty. call panasonic and see if there is a servicer in your area. our company is in dallas texas.

Why my tv have dark screen

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.
