Re: Sony KV30hs420 0 Stanby Light Timer Blinks 3 times...

Led blinking Three times means B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672. If you have electronic knowledge you may be able to fix it. Let me know if I could help you further.
Hope this helps.

It does not go on becuase of the standby timer

It sounds that the standby light blinks, and the set do not turn on. These blinks are fault indications. Fromm these number of blinks, you can get an idea about the faulty circuit part inside. Count these blinks. How many occurs at one time switch ON. Count it for at least to times switch on. If you wish to get more details about the blinking codes to Sony TVs, check this site.

Hi my tv seems to be on standby/timer and will not come back on how do i get this problem fixed

It sounds that there is no communication with IIC bus with other ICs. Check whether the standby light blinks when you turn ON the TV by its Power Switch at it front panel. If blinks, count the number of blinks. Check this for more details about the blinking codes to Sony Wega TVs. If it does not blinks, make sure that the main system control IC has the fault.

SONY KV35S40 Light blinks continuously when power is pressed

hello there,

Many of the later model Sony TV’s have a built in self-diagnosis function. If the timer/standby indicator is blinking, this could be an indication of a problem with the unit. The diagnostic blinking will occur automatically with no action required by you to engage it.

The timing of the blinking you see would be as follows: two to nine blinks, (depending on the fault), about a third of a second apart, then a pause for 3 seconds, then the two to nine blinks about a third of a second apart again.

The blinking light indicates power supply failure. There are two integrated circuits on the power supply board that have to be replaced. I estimate repair costs in the range of $375.00
