Hi, If all else fails, try do a hard reset. You can verify from your manual, but in some units, this is merely unplugging the unit from mains for a couple of hours. Try again, if it still shows error codes (blinking lights) you probably have to seek the services of a qualified professional. Hope this be of some help/idea. Good luck and kind regards.

SOURCE: Sony KV34XBR800 Red Flashing Standby Light No Power

The red light should be blinking a code. For example it will blink 4 times pause then 4 times pause or 5times pause 5 times pause, whatever the error might be. Let me know what it is and then we can help more.

SOURCE: Standby LED blinks 4 times

Hi there,

4 blinks on a Sony Bravia indicates a backlight/inverter (aka ballast) problem. These ballasts are regrettably only available with an entire LCD panel. :( You may perchance be able to find a parts outfitter online that scraps out TVs and have a used ballast.

Typical backlight problem on an LCD shows up as the screen lighting up for a second or two and going back off. The 4 blinks just confirms your problem.

If the Standby light is blinking at the front panel of the TV, it seems that there is an internal malfunction occurred in the TV. I will forward a link to a page where you can get more information and troubleshooting steps for this issue. http://www.kb.sony.com/selfservice/microsites/search.do?cmd=displayKC&docType=kc&externalId=C399467 Please perform the steps provided on the page. If the issue still persists then service of the TV is required.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

The green power light wont turn on. the red light is on. pushing the remote power and manual power do nothing to turn box on.


Red LED light is an indication of standby mode only. It means you haven't a hight voltage that's why your tv will not power on and the green LED is dead also.

I've advice you to look for a qualified technician because you have a faulty parts on your low voltage power supply mainly on the regulator section. It is quite technical so you need an experts to isolate the faulty parts on the board. Your set also need to resolder for some dry joints because it is also one of the caused why some parts are damaged.

Thanks for using fixya!

Power Issue


Now,u plug in the tv u get a solid red standby power red LED light in the front of the LCD panel right?When u push the power button on the remote u hear a clicking sound?Only one clicking sound,not the power supply board problems.It the Tuner board problems.But u can make sure it the power board problems or not.By taking the tv aparts check the power board,that board where the a/c power cord goes into it.Look all around the power supply board check for these leakage capacitors,they alway bulges up it top or puff up it top.No bad leakage capacitors,then it not the power supply board problems.

Unplug the TV for maybe 10 minutes, then turn it on. Sometimes these units simply need to recycle. If that doesn't work, you've likely got serious problems.

Internal led of ML350 server is glowing.......how do i resolve it?


Hi Franceso, plz specify
Is it powering ON ?
Which LED is glowing?
These leds are there on the front panel :

1 Power On/Standby button
2 System power LED
Green = Power on
Amber = System shut down, but power still applied
Off = No power

3 Internal health LED (Wave sign in BOX)
Green = Normal
Amber = System degraded. To identify the component in a degraded state, refer to system board LEDs.
Red = System critical. To identify the component in a critical state, refer to system board LEDs.
Off = Normal (when in standby mode)

4 External health LED (power supply)
Green = Normal
Amber = Power redundancy failure
Red = Critical power supply failure
5 NIC 1 activity LED Green = Network link
Flashing = Network link and activity
Off = No link to network.
6 UID LED Blue = Activated
Flashing = System remotely managed
Off = Deactivated
7 UID button

If it is Internal health led then any internal h/w issue is suspected.
If it is external health led then any power supply or power source related issue is suspected.
Also check the status of the server & its IML (Integrated Management Logs) in ilo (Integrated Lights Out ) if it is configured. (2nd RJ45 port in rear)

Also make sure the cabinet is properly closed.

Amp has Red LED light on.


Disconnect all speaker wires and signal cables from the amp. If it powers up, the wiring needs to be checked. If it still shuts down, the amp likely has blown output transistors.
