Thanks for the reply.
Unfortunately I do not have
good news for you. There is no sequence of buttons you can press the reset the
TV, and it will require circuit testing and component replacement to operate
There are basically three
problems that would cause this, the Power Supply, the T-Con boards, or the LCD
panel itself has failed. Voltages need to be measured at the power supply
outputs, using a DMM with nothing connected to it but AC Input. If the readings
are proper, then the other boards need to be connected one at a time, until one
causes the voltage to shut down at the output. If the supply outputs power with
all of the boards connected, then the T-Con needs to be tested. The T-Con will
run you around $300 to have replaced. If the T-Con tests good, then the LCD
Panel has failed and will cost you more than a new TV (around $700) to have
replaced and it is not cost effective to repair this set.
If you do not have
experience testing live voltages on a circuit board level, then I would suggest
using the link below to locate a tech in your area:
