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.

SOURCE: Sony Grand vega 55" will blink green for three times than red

Your problem is your thermal fuse.It is located around the bottom of the compartment that houses the lamp. You will have to remove the lamp and take the bottom back panel off. Then you will have to remove the fan. I ordered the thermal fuse so I would know what I was looking for when I started to replace it. If you take your time and are patient enough you can fix it yourself. I fixed mine and it's working great.GOOD LUCK!!!

SOURCE: The power/standby light blinks red

Hi,
Please make sure lamp cover is fixed properly as it was removed to replace/ check lamp in tv.
If lamp cover is not fixed, tv will not turn On and red light will blink 3 times.
Thanks.

How do i set convergence of red,green ,blue through service mode


Most common cause for this on the Sony KDL 40EX520 is that the connections to the screen across the top edge of the panel become loose causing blurred picture, mis-aligned colors etc. The Fix requires dis-assembly (Removal of the entire case) and re-seating/resecuring the connection across the top of the LCD Panel.
There is a pretty detailed video of the process (less the disassembly) here: https://www.youtube.com/watch?v=80PfZXFGDvQ

Flashing red light


This is a sony tv. The amount of times the red led blinks is a indication of what the fault is. Contact sony and tell them the model number and the amount of blinks the led is showing and they will diagnose the fault.

The tv went blank @ the red led is flashing continuosly sony kds-60a2020


Hi,
If its lamp light on tv front that is blinking red then lamp is dead/ broken and need to be replaced. Lamp replacement procedure is easy and written in user mnaual of tv.
If it is standby/ power light that is blinking then please count how many times it is blinking after three seconds pause and let me know to diagnose tv problem because it is an error code that has info in its blinking.
Thanks.

No picture or sound


Does anything start to work? Any of the three fans start to turn, Lamp ignite, etc., when you press the power button or does nothing happen before the Red LED starts blinking. How many times does the RED LED blink?
