The most common cause of Failure in this unit is power supply failure caused by failed capacitors. A visual inspection is The easiest way to identify and confirm bad capicitors on the power supply. Such a capacitor will show one or more of these symptoms: 1) Bulging of the vent on the top of the capacitor. (The 'vent' is the impression stamped in the top of the can. The impression forms the seams of the vent. It is designed so that if the capacitor becomes pressurized it will split at the seams relieving the pressure rather than making it explode.) 2) Sitting crooked on the circuit board as the bottom rubber plug is pushed out. 3) Electrolyte (a crusty brown substance) leaked onto the board from the base of the capacitor 4) Venting from the top of the capacitor, visible as rust-like brown deposits, or a visible hole in the vent Once the power supply is repaired or replaced your tv should work normally

Morning, it flashes red light six times


From the manual:

Press the (ON/STANDBY) switch to turn on the projector. If
the power is not turned on, disconnect the AC power cord, then
confirm the ON/STANDBY lamp is turned off. After about 10
seconds, reconnect the AC power cord and turn on the power
again. If the indicators still light up, the electrical system has a
problem. Consult with qualified Sony personnel.

I have a Plasma TV with black screen and 6 red light flashes.


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience.

Flashing standby light


Flashing red light can sometimes be fixed by holding down the power button on TV until it stops flashing then turn it off then on again. Disconnect everything except power cord before trying this. Mine was fixed this way and saved $500+ repair. Still going over 6 months on. Worth trying.

(ii) Next, reconnect all the cables after two minutes.
(iii) Please make sure that the power cable from the TV is directly connected to a functional wall outlet.

Please follow the steps that are mentioned below to reset the TV to the original factory settings:

(a) Turn ON the TV.
(b) Press and hold the Power button on the Remote Control supplied with the TV, then press the Power button on the TV front panel.
(c) Release the Power button. The TV will turn itself off, then back ON again.
(d) Next, release the Reset button on the Remote control.

If the standby light still blinks then the issue may be with the projection lamp in the TV and requires replacement.

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 - http://esupport.sony.com/US/perl/webtree.pl?template=EN&mdl=KDF55XS955&content_id=68&category_id=11&problem_id=52

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.

If a red light flashes for more than a few minutes,disconnect and reconnect the power cord.
Check the TV/VIDEO settings
make sure you have inserted the batteries correctly to remote control.
Try another channel to rule out of station trouble.
if the problem continues may be a power supply problem.
good luck ! please dont forget to vote if this suggestion is helpfull.
