Question about Sony KV-36FS17 36" TV

1 Answer

Led light blinks even when TV is off.

My TV is 5 years old. For the last week and and a half, the Led light is flashing. It flashes 5 times, stops for a few seconds, and then flashes again. This is happening all the time, even when the TV is shut off. We don't use the remote that came with the TV, we use our Cablevision remote. However, I was dusting the remote control holder, so I took them out and put them on the couch. Does anyone know of a button on the remote that could have been accidently hit? If not, so far the TV is working fine still, but does the led flashing mean something is wrong? Thank for any help, Marie.

TV stopped working, how can I fix the problem below?

Back-light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
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.

Dell battery alternate led flashing

How old is the battery? Is it a replacement? My batteries usually last 4 years, more or less.

You can check the Error code by doing the following.

On the Front panel hold down the Device and Menu Button for 5 seconds. The LED light will then start flashing the first set of flashing lights is for the "1"5 part of the code it will then pause for about a half second and start the ones place 1"5". The code will repeat 5 times before going off.

The Error Codes: 12 - Normal Operation; 21 - X-Ray Protect; 22 - Short Protect; 23 - Loss of Horizontal Deflection; 24 - Loss of Vertical Deflection.

The problem may also be in the power supply when you first plug the device in check how many times the Led blinks if it blinks for just over a minute the power supply is working fine. If the Led blinks repeatedly and does not stop the DM is not running.

Hi! GREAT site! We have a Sony SXRD KDS-R60XBR1 Projection TV and it stopped working last night... We are getting FIVE red blinks! What does that mean? Fans, bulbs.... ??? Thank you in advance for any...

5 blinks if for the ballast that powers the light. You can try changing the bulb first, if that doesn't fix it then I believ it will be your ballast. If you haven't changed the bulb before It could probably use one anyway, and you could keep the old for a spare.
Here are some more from sony on this.
According to Sony:

Red LED Flashing four(4) times
o Fan not plugged in
o Foreign object hitting blades
o CN2301 on ASU board not seated or connected
o ASU shield touching S1 board

Red LED Flashing five(5) times
o Interconnect harness from Lamp driver 5-pin to ASU 9-pin board not connected
o Lamp driver failure
o Bent pin on Lamp driver 5-pin connector
o DSU to C board harness not locked
o CN6501 on G board not seated or connected
o Lamp failure
