Dear Friends,
Any TV in-order to function properly it needs regulated power supply (That too regulated) for all the remaining sections like vertical section, audio section etc. Regulated means a constant steady voltage irrespective of fluctuation happening in the main electricity.For example even if mains wire recieves 10 v less to the actual the smps should produce stable voltage. There are many plans for SMPS to design. One may use STR , one may use transistor.
Nevertheless the plan is different the intention will be common.That is producing regulated voltage.
It is difficult to have all the diagram all the time. So it is very important to have a general trouble shooting idea.
After refering 50-60 books and 8 yrs experience I have designed a general troubleshooting tricks.
So, my next posting on http://ecare-electronics.blogspot.com/ is general tricks of SMPS repair.
Please give me 3 hrs of time I am going for lunch now.
Regards
Raghavendra
