A power regulator or a sweep power supply problem. The power regulators in the main power supply, and will have or start with STR###-## The # are numbers or letters. This is a repair that should be done by an amature or layman. This is a solid state set, and there are no user replaceable parts inside these sets. Have it looked at by a trained tech, Good Luck

Hey there! Just replaced the lamp in my sony KDF70xbr950 and now it will not even come on I have 4 flashing red lights and then goes back to a solid red light can some one help!! ...

The LAMP light is flashing or blinking.Solution
If the LAMP light is flashing, first attempt to perform a power reset on the television. If this does not resolve the issue, then the lamp inside the LCD projection television may have burned out and will need to be replaced. If this appears to be the case, consult the Replacement Lamp Part Number table to determine the correct replacement lamp for use with your projection television.
NOTE: The LAMP light is not the same as the POWER/STANDBY light.

How to perform a power reset on a Sony® television.Solution
Turn off the television.IMPORTANT: For a projection television that uses an internal lamp, wait 5 minutes after turning off the television to allow the lamp to cool before continuing with the following steps.Unplug the television power cord from the electrical outlet. Let the television remain without power for 60 seconds.Plug the power cord back into the electrical outlet. NOTE: If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.Turn on the television.

Tv went off while watching a program power standby red light blinks 6 times then pauses then repeats tried unplugging unit waiting a few minutes then replugged same results nothing. can anyone help me ?...

Here's an excerpt from the Sony Manual online. And the link -

The POWER/STANDBY (red) indicator flashes three times
If your power/standby indicator is flashing in a pattern of three flashes, this may indicates that the lamp cover is not attached securely. Follow the directions in the Operating Manual under changing your lamp that related to closing and securing the Lamp Cover. Ensure that the Lamp Cover Door is securely fastened by tightening each screw.

The POWER/STANDBY (red) indicator flashes continously
If your power/standby indicator is flashing continuously, and the lamp cover has been secured, your TV may be in need of service.

The POWER/STANDBY indicator is lit up green (not flashing)
A sustained green light indicates your TV is on.

The POWER/STANDBY indicator is lit up red (not flashing)
A sustained red light from your power/standby indicator simply indicates that your TV is in standby mode. This shows you that your TV is ready to be turned on with the remote.

Is it the power light and not the lamp light? If the lamp light is flashing then replace the lamp.

Sony Grand WEGA KDF-60XBR950 60 green orange green red flashing light

3 blinks is a lamp cover error, did you make sure that the lamp cover is screwed in tight? Also check the lamp cover for deformity, there is a problem with your model where the set over heats and melts the lamp cover a little causing it not to make connection with the lamp cover switch. Let me know if you find either of these problems? If not we can troubleshoot a little further.

Samsung HLN467W Flashing "LAMP" LED

remove the lamp and visually check if inside looks broken.if visually do not see any thing wrong,check if you have 300 volts dc supply on the ballast which starts the lamp.if you do then the ballast may be defective.if you do not then the power supply should be checked.
the lamp should always be tried first especially if is older than two years.
note - be aware about the switch at the door lamp.the door should be closed,otherwise tv will not work.if you remove the back cover,make sure to bypass the switch temporarely so you could work on the set.

The audio should not work if the lamp has expired, but it would be the best place to start. The led flashing 6 times is a complete other issue, and needs the thermal fuse changed.
