This can indicate a problem with the high voltage circuits. Since this is a new set, it should still be under warranty. DO NOT open up the unit as that will void the warranty. Return the set or request warranty service. Note the 8 blinks when you request service as that should allow them to bring the correct replacement parts.

Keep us posted.

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.

Some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement.

I have a sony bravia kdl 37m3000. We have cable and the wide screen would not go away so we unplugged the cable to reset the tv. Now the cable and the tv comes on but no picture.


Make sure you change the input that the cable is coming in on, If you was watching in HD mode then you was using an HDMI or compontet hook up.Look on tv remote for Video input button to select the componet input 1 or 2 or HDMI inputs which it is connected to. Look for a button on the remote called TV/VIDEO or INPUT
