Hi,
Issue seems with power supply board in tv and most probably few electrolytic capacitors are leaky in output section of power supply board that are causing problem.
A leaky capacitor does not hold specific volts charge so output volts become low thus tv circuits do not function properly. TV turns On after 10 minutes also indicates that power supply out volts reach up to proper level to make tv circuits functional.
Please check power supply board and replace all capacitors in output section to solve this issue. If you are not familiar with soldering work in circuit board, call local tv repairman to do this job for you.
Hope these info will help you.
Let me know if you have additional question.
Thanks.

LCD TV IS NOT SWITCHING ON


Use the remote to change mode, or hold power on button for a few seconds until light goes out. Then retry.
