Hi, this is a very common failure, you need to replace 2 IC chips on your power supply board, marked on the top of the IC`s is this number: MCZ3001D you can purchase them here if you are very proficient at soldering & un-soldering, and the board has to come out of the tv to do this, you might want to call a tv man for this one, but it will fix your set, happy holidays, BMW Rider

If you have the above model, then the four blinks indicate a backlight failure. The back light inverter board might be defective or the voltage from the power supply (+24v) is low or missing.
Let me know if you require further assistance.

12 blinks of standby light indicates 'Scanrate error'. You must have thorough knowledge in electronics to proceed. Actually, this is not a user repairable fault. it is very skilled work.
