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?

My sharp tv model 20V L80M always damage the str g5653!


If your SMPS IC is getting damaged all the time , you can easily source an universal SMPS unit with the required + B voltages to power your TV and this will be more reliable and will not fail as the circuit is much stable.
The failure of the STR is due to poor feedback, poor components int this section or the SM oscillations, or a faulty SM transformer.

Sharp tv 20V-L80M standby only


If not power up even by remote control then check the the H-out transistor for short, open fusible resistor in line with the b+. This is the most common fault of your problem.
Needs a technician to isolate the problem.

Thanks for using fixya.
