Question about Televison & Video
SOURCE: television power led blinking
are you sure that you are checking this correctly?
What is the location number for this regulator?
If its the main regulator, what are you using for ground on your meter? Also, isn't the part number marked on the regulator?

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?

have an oscilloscope? trace the audio. I'm assuming you have a scope if your replacing I.C.s in TVs. make sure your volume is up a little bit when checking the amp section. make sure all wires are connected (speaker too).
make sure tda is getting voltage (view tda7056 datasheet for pinout data)
make sure it isn't an eprom fault
