SOURCE: power supply problem busted fuse
Hello, in most of the new LCD and Plasma TV-s there are special IC-s you can not find in regular stores. Only way to solve this is to contact the Philips Service and order the IC. In most cases the only available items are the complete boards. If you need more info please advice.

vscan is a voltage used to setup the picture for the panal. It goes to the y sus board. The problem is at the power supply or the y sus board. You can check these with a meter.

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.
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
You may also replace the power
supply board, check it 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.
