BLINKING STANDBY LIGHT AND NO POWER

Standby light blinks but the tv won't power on. I try turning on the TV, either via remote or straight from the TV and no picture nor sound. The red Stand-By light flashes 9 times and then stops and seconds later repeats. Every now and then we get lucky and the TV will turn on but it appears to be by a random pushing of the TV and power buttons--but never the same way twice. Any suggestions?

There is a possibility that the power switch capacitor has bubbled or leaked a remedy is to unplug the unit from the outlet for at least an hour then try to power it back on.

i will try to look for more information about other work-around's or which of the other parts are defective or almost defective, that is causing the problem.

My tv wont turn on by power button or remote. white light keep blinking.


How many times this standby/power light blinks at one time switch ON? Count it carefully. These blinks are fault indication, and known as blinking codes. From the number of blinks occur at one time switch ON; you can get an idea about the faulty circuit stage inside the TV. This will make repair easy. For more information, check the link http://electronicshelponline.blogspot.com/. If the blinks continues, and non-stop, the fault should be with its main system control IC, and with the memory IC.

How do you tune Sky+ remote into Sony KDL46W5710 Television


The Sky+ remote should automatically default to Sony TV's. Leave the batteries out for a few minutes and try again. The Code for Sony is 0000.
Or try this :-

With TV and sky box on.
Press the 'TV' button on the remote.
Hold down the 'select' and the 'red' button (of the four coloured buttons) together, until the red light on the remote blinks twice. (takes 2 seconds)
Press the 'TV' button again.
Now enter four zeros, the red light on the remote should blink twice.
Press the 'standby' button (top right).
If the TV turns off, then press 'select' and the light should blink twice again, job done.

If the TV does not turn off then press 'TV' followed by 'standby' again.
Alternate pressing 'TV' 'Standby' until the TV turns off.
When it does, finish by pressing 'Select.
Check the red light on the remote, if it blinks 3 times, then it has run out of options for 0000.

Standby light stays on and the tv will not go on


Please check batteries in remote that seems not working. Sony TV would either turns On or standby light will blinks if TV gets any internal problem.
You question shows standby light stays On that means TV does not receive power on command from remote.
If standby light is blinking in sequence, let me know how many times it is blinking and also intimate exact model number of TV to find out possible solution.
Thanks.
