My sony TV, when I press the power button it sounds like it is going to turn on then the standby button blinks 10 times then stops for 30 secs and then blinks another 10 times. What is wrong?


Hi,

Flashing of the standby LED light 10 times (KP-46WT520) is a "High Voltage Protection".
Affected parts are as follows :
• Q8014 or Q8013 have shorted replace along with R8051 on D Board.
• IC8005 is damaged (D Board).

You must know how to test transistors, resistors using the multimeter if you are going to DIY.
If you don't have necessary tools and test instrument and can't troubleshoot the unit yourself, I would advice you to seek for an assistance of a qualified TV Technician to isolate the above faulty parts.

Hope I helped you.
Have a nice day!
Thanks for using Fixya.

BLINKING STANDBY LIGHT AND NO POWER


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.

Sony kp-46wt520 standby light flashes 10 times. Does not power up.


hello Check Q8014 and Q8013 for shorts, leakage, or bad solder connections on the " D" board. If the transistors are bad, check R8051 and IC8005, also on the "D" board.

Sony kp-46wt520 rear projection tv: standby light flashes


Two things here.

1) This is a CRT based set so there is no "lamp" involved.
2) The standby light should be blinking a repeated count of blinks with a 2 second pause between counts. Please report the exact count here. This will indicate the circiut in which a problem was detected.

With the above information, we can provide you with a more detailed description of the problem as well as the likely solutions and cost.

Thanks,
Dan

NO SOUND AUDIO


Just to be sure, it isn't on SAP is it?
That would be under the MTS/SAP button.

If that's not it, are there any other distinguishing features that you notice?- A buzzing or a clicking or peculiar light flashing?
I wouldn't be able to help with that, but the next person might!

WON'T TURN ON


nine blinks means that there is a short inside the set you will have to find a tech to troubleshoot the set most probably is the G pcb
