Facing TV Problems? Ask a TV Technician.
How long have you had the set for and when did the problem occur?
Was it after a storm or power outage?
Are there any signs of life at all on the TV (Power light blinking, steady, click sound when power is pressed, etc.)?
Please disconnect the set from AC power, then press and hold the power button on the TV itself (not the remote), for 10 seconds. After another minute, plug the set back in and press power once. Do you still have the same problem?
short inside the set stopping it from fully powering up.
It is most probable that there is a failure on the power supply board inside the TV. Commonly the capacitors on this board will receive a surge and then fail. They can sometimes be visually verified by removing the rear of the set and inspecting them for bulges or leaking fluid at the top or the base of the caps. This is the most common mode of failure for these sets.
Seeing as you are barely into owning the set, you should contact the retailer and you will need to ask them where the closest service location is to have the TV repaired. I wish I had better news, but there are no buttons you can press to fix this and the TV will require service at this stage. If you need further assistance, let me know.
That makes sense.
The only power supply for this TV that I could locate, is a refurbished unit as well for sale at the link below:
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. The Power Supply Board is the one inside the TV that the power cable directly attaches to. Any capacitors on this board that are bulged, or leaking a brownish fluid around them are faulty and could cause the problem you're having.
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, and the small board that has the Power Switch. Turn the power switch on, and then measure the voltages on the Power Supply. 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.
A good source to locate replacement boards is http://www.shopjimmy.com/ and http://www.discountmerchant.com/
Do all of the outputs drop even with no other boards connected to the power supply board?
