I suggest do a factory reset - with tv off, point control at tv press in order mute/1/8/2/power when screen comes on, go to RESET, press enter and set will turn off. When you turn it on it should come up just like first out of the box.

Testimonial: "I have tried the above and that didn't work either. I know the power supply is fine. I know the TV is recieving from the remote. Press power on the remote and after five flashes the red light just stays on. What could it be? Many thanks. George."

SOURCE: Red Light Flashing 6 times

When the lamp fails in this unit, often the thermal fuse opens. The error code is 6 blinks. To replace this part requires a great deal of deal of disassembly.

SOURCE: Sony KDF-E55A20 55 in. LCD... Problem red light flashes 5 times

A 5 blink error indicates a bad lamp driver. However a lamp may possibly cause this too. I suggest putting a new lamp in if you have one just to verify the lamp is not the problem. If it still fails with a new lamp then the lamp driver is the problem. This part should be replaced by a Sony authorized servicer. The lamp can be replaced easily by you. The lamp replacement instructions are in the TV's owners manual. Good Luck

SOURCE: tv shuts off spontaneously. red power light blinks.

re: sony flat panel lcd tv mod. # klv s 40a10.
No power. When power button is pressed, nothing happens.
The stand-by at the power supply ( cn6201) measures to be 3.47 v. instead of 5 v. However, when I unplug cn6201 (5 pin connector) I can read 5v. at the power supply.
Any suggestions?

5 flashes - Lamp Driver - (lamp driver faulty)

This is the error code that usually means the ballast (it is the power supply for the lamp) is bad.

I cannot stay connected to internet, my model 2701HG-B 2wire at&t dsl will start flashing red then disconnect me from the internet or my game site, how can i get this to stay fluently connected please!


You might want to try disconnecting everything EXCEPT the power cord. If you still get the red power light (it should stay there forever) then bring the gateway to Radio Shack or somewhere they have a 5 volt DC @ 2 amp power supply and plug it in for 5 to 10 minutes and see if the power light then stays green. If it stays green then all you need is a new power supply! If not, then the gateway is fried. Mine keeps going from a solid green power light to a flashing green power light and I can hear a relay click every 2 minutes at which time a pop-up say "ethernet line disconnected". I tried new power supply etc. to no avail! It is fried after 1.5 years! No more 2wire for me!

Powermac g4 will not turn


this is a common problem with G4 Quicksilver. Your power-supply is defect and has to be replaced. I have 4 G4s in my lab with the same symptom: a short flash of the power-button light, sometimes it turns on, but mostly the machine is dead.
