Electronics Repair Questions? Ask an Electronics Technician
Hello, my name is XXXXX XXXXX I will be glad to assist you.
How long have you had the set for, and when did the problem occur?
Also, is the red standby light on steadily, or blinking?
Thanks for the reply.
Are you saying you've only had the set for a month?
If you go the TV itself and press the power button, does the button make a distinct clicking sound?
Yes, that is the most common problems with all LCD technology is the caps on the power supply board. That does not mean that is definitely the problem though, the TV is not blinking an error code and there are other circuits in the TV that could have failed. Capacitors also are not a snap in part and they require removal of the rear panel of the TV, and also soldering to replace. If the TV is only 3 months old, you will void the warranty simply by opening it up. I would first suggest contacting the retailer to locate the closest service center in your area. If the problem goes beyond the caps, the TV could be in for a very costly repair and you do not want to open the set as you will Void the Warranty.
If you need further assistance, let me know.

The first thing you'd want to check is the caps on the power board for bulges or leaking. Any of these needs to be replaced.
Please only proceed if you have experience measuring live voltages on a circuit board level.
Next, use a DMM set to DC volts, find a common ground on the power supply and probe all of the Outputs for voltage (correct voltages will be stamped on the power supply at the outputs). Do this with NOTHING connected to the Power supply but AC power. If a voltage is missing/ fluctuating, then the power board needs to be replaced.
If the power supply outputs its rated voltages, then connect the other boards one at a time until one causes it to shut down. This board would have the short causing the supply to SOS, and would need to be replaced.
