I went ahead opened the back cover and surprisingly noticed it's pretty dirty inside after 2.5 years of usage, and there is a thermal fuse to protect the ballast power supply. Spend 99 cents replaced the thermal fuse and the TV came back alive. I am surprised that it's such simple to fix the problem vs many others frustration.

LCD TV is more fragile than the traditional TV as it uses expensive HID lamp. So the cooling system inside is very critical to prolong the lifetime of the lamp and the special power supply. Dirt collect inside is probably the major cause to degrade the cooling system. Make sure you clean them (two fans and a lens) whenever you have a chance.

We have a 2007 Sony Bravia 46" KDL-46VL130. There is not sound or picture. When we power it on the green light comes on blinking once and then the red light blinking once and then the green light stays on....

Does the front light stays green ? Or goes back to red ? The back-light going on/off maybe the problem, but it shoul return with a red blinking led (4 times ?) and if so it can be a power inverter problem.

All the troubles I've seen with this model are because of the LIFI lamp. Panasonic warrants the lamp assembly for four years from date of purchase. Call Panasonic toll free hotline or go online for an authorized warranty shop. Good luck
