Bad or blown capacitors. Look on circuit board for domed, bulging or leaking capacitors. USE CAUTION!! high voltage capacitors can electrocute you. They should be properly discharged before working on circuit board

The power supply board of the television is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.
I hope this will help in solving the problem....

SOURCE: TV won't turn on
Before going OFF, the standby LED might blink. These blinks are fault indication. The number of blink should be counted. Count the number of blinks at one time, before the TV goes OFF. [eg: 4 blinks Power SOS P Board; 6 blinks Driver SOS 1 SU / SD / SC Boards
(SC energy recovery circuit)] and so on. you can get more details from this site named 'Electro-help'. You can reach it by searching the keyword "electronicshelponline" by internet.

Switch off TV, switch off power, remove plug and wait for 48 hours and retry.
If problem persists, I suggest it is better to refer it to a qualified service
technician, since the back cover has to be opened for investigation/rectification.

Power issues with ProForm treadmills fit into two categories: the power does not turn on or the power shuts off when using the treadmill. If the power will not turn on, make sure that the treadmill is plugged into a working power outlet. In addition, you should use a single-outlet surge protector for the treadmill. Single-outlet surge protectors protect the machine from any voltage changes that may occur in your home.
If the machine is plugged into a working outlet, make sure the safety key is in the keyhole on the console. If the safety key is not plugged into the machine or if it is pulled out during operation, the treadmill will not operate.
Finally, make sure the circuit breaker located on the frame near the power cord is set to "Reset." The circuit breaker is set to "Reset" if the top of the button is pushed in. When the breaker is tripped, push it back to the "Reset" position and wait five minutes before powering on the treadmill.
If the ProForm treadmill shuts off during operation, check the power cord and circuit breaker as described above. You can also try removing and reinserting the safety key.
