Polaroid will not release component schematics not even to service centers as they are designed to replace the entire modules while under warranty out of warranty there is very little Chance of obtaining new replacement parts. As i have a 2006 LCD and a 2007 Plasma Polaroids and polaroid told me they are considered a disposable TV replacement parts are not available and suggested that I try ebay

Buy the green light going on means Standby is ok. Next, would be to locate the plug coming from the main board to the power supply and find the post that says PO which means power on. With your meter on that post, press the power button as see if the reading goes High, if it does then the main board is able to turn on the power supply. Next, find the plug on the power supply that goes to the inverter( the long board on the side) remove it and see if you have 24 volts coming out of the power supply when you press the power. If you do, then the inverter board is bad, if you don't have 24 v, then the power supply is bad. There are NO diagrams available for these set other than a flow chart if you can find one. A regular svc tech does'nt need a manual for these anyway.
Let me know how you do Kathy ?

Manufactureres usually keep their schematics to themselves however you may be able to contact them to purchase a new power supply.

I have tried numerous times and the TV manufacturers will not sell parts or diagrams to consumers.You have to be a repair shop with a username and password just to view the stuff.Here is one possibility.
I will try for others...hang on please.Here is another possibility.All I usually find is user's manuals which are free few and far between.Schematics just aren't out there.
Sorry to have to tell you that.I like to fix my own stuff too.There is nothing more I can suggest with all the limited access.Good luck!Maybe if you take the regulator out and ask a shop?
