Sounds like something went bad in the power supply. I would check all the capacitors to make sure none are raised on top or leaking. If all the caps look good then it could be a bad transformer. A new power supply board should fix it if you don't want to desolder, test and replace components.

Hi nycozza,

Here are some basic steps that will help you fixing the problem.

I'm assuming that your unit is dead set without an standby LED light and your outlet is live.1.Power cord - check the cord it might be opened (no continuity).This is due to frequent bending,pulling. 2. Power switch - check for dry joints, open contact. 3.Check the internal fuse- sometimes the fuse fail because of the power surge, replacing with new one will cure the problem, If this is the case I would advice you to use surge protector/AVR (Automatic Voltage Regulator). However if the fuse blew again this is an indication that you have a shorted parts in the power supply, you may visit the linkhttp://www.fixya.com/support/r8053361-fuse_keeps_blowing for more info. If no reaction and still the unit didn't power up then you have an open parts on the power supply.

4.If you see that the fuse is intact , don't attempt to touch anything because there some fatalcomponents stored electricity enough to hurt you with a simple mistake only. I would advice you to look for a professional to troubleshoot the power supply. If you want to repair it yourself make sure that you have necessary tools and test instrument. First check bad solder joints(re-solder all cold solder), leaky electrolytic capacitor(sometimes it has bulged at the top but not all, you better have a capacitor checker), open/shorted regulator transistor/IC(mounted in heat sink), open fusible resistor (caused by shorted regulator Transistor/IC), shorted zener diode.

You may also replace the power supply board, try online like ebay.com and shojimmy.com.

Also check if your unit is under warranty before opening the back panel, it will void the warranty. Avail it because the manufacturer of your unit will fix it for free or a little charge only.

Hope I helped you.

Have a nice day!

Thanks for using fixya.

Why my TV does not turn ?


Assuming that you don't even have a standby light on the led.
Here are some DIY steps that may help you fixing the problem.
  1. Check the power cord - check the cord it might be opened (no continuity).This is due to frequent bending and pulling.
  2. Check the internal fuse - sometimes the fuse fail because of the power surge, replacing with new one cure the problem. However if the fuse blew again then this is an indication that you have a shorted parts on the power supply. If no reaction and still the unit didn't power up then you have an open parts on the power supply.
  3. If the fuse is intact then you have a faulty in the power supply or on the load. You might have an open fusible resistor,open volt regulator ic, shorted H-out IC.
The #3 should be done by an expert or qualified technician because isolating the problem on the regulator section is technical.

But first check if the unit is under warranty then avail it because the manufacturer will fix it for you for free or a little charge only.

if new fuse fixes prob, it is most likely going to happen again. then you'll need to isolate window that is problem.(last one used before fuse blows)go from there. GinoR
