The probable cause is with its main board. Not probable, it is. Contact any service technician. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy. http://electronicshelponline.blogspot.com/
Your tv set may have an overload in the supply line. Check its rectifier diode and filter capacitor. Another approach is to check if the DC supply line of the switch mode controller IC (UC4842 for exemple).is present (10/12V). If these are OK, replace the switching MOSFET transistor and check the source resitor for open circuit.
