SOURCE: sony KDFE60A20 TV turns off and on with Red light blinking 5 times

Same problem here. 5 blinks is video related. I've been told to clean the screen by the lamp, as they could be clogged and causing it to over heat. Going to give thet a try first. I'll post what happens...

4 times blink error shows that any FAN is not running in TV as there are 4 fans in this TV.
Please check fan connectors and make sure all are plugged securely.

SOURCE: 14 blinking red lights (standby) sony lcd

14 times means the LCD panel is defective. I just had one of those tvs in my shop. Sony will take care of the panel replacement in warranty.

Please count Sony KDL-46V3000 standby light blinks as there would be interval of 3 seconds between blinks. Let me know how many times light blinks as its an error code.

SOURCE: Sony KDL-46s2010 4 red light blinks

I would suspect one or more of the miniature flourescent backlight lamps. One way to confirm this would be to power up the set with a grayscale image at 40 to 60 IRE. If one or more lamps is failing to light, a slightly darker horizontal area in the grayscale will give it away. Unfortunately, Sony will not supply any of the backlight components apart from a new LCD panel. Sorry.

Klv32s310A sony bravia gets start on with green light and after a second turns to stand by mode blinking the red light 6 times after each 2 second interval


Hello Sagar,
green led means tv powered on and status ok.
Red blinking light almost always means defect, overcurrent or overload.
6 blinks for Sony lcd flat tv means trouble in backlight circuit, or backlight inverter (backlight illumination or lighting makes your tv screen visible).
common problems in the inverter circuit, which drives the backlight, or shorted drivers, or short-circuit transformers or open circuits.
You should find the problem in the inverter circuit, or in the power supply board or in the main board.
Also look for bad capacitors (electrolytic caps) which are bulged and swollen on top.
Decoupling plugs from printed circuit boards can help you in finding the problem board by elimination method.
If you power up the set after unplugging certain plugs on f.e. the inverter board , this could result in getting a green power led and concluding that this board is faulty.

succes,
Walter from Antwerp, Belgium.

My sony bravia kdl46v5500 shows the 'digital fe/be error'. The stand-by red light blinks 10 times after the tv shuts itself off. The shut-off and then automatic turn on happened earlier after a while


  • i think you have a power supply issue but this model has been known for main boarde issues , if you replace the main make sure it is one that has the factory software loaded

Sony vega tv turns off after 10 minutes and a red light blinks three times


to check well how many times blinks.
2 times - to mean overcurrent
4 times - vertical deflection stopped
5 times - white balance failure.
any way I think that is an soldering fail in the board.

Moe,You have several Broken Conns via your Mother Board after doing about 500 in the Past 8 yrs,What you need to do is Get a Magnifying Glass and look at the Bottom of the Main Board and look for Ring Breaks around Conns *Note,Any thing on a HeatSink or Plug Conns,Will be Checked First,Use 60/40 Solder and a low heat soldering Pencil to Fix Good Luck ttech
