Turn the TV off, unplug it from the wall. Hold down the power button on the TV for about 20 seconds. Reconnect it and try to turn the TV on again. If the problem persists the TV is in need of some service by an authorized service center if under warranty. If not, look around for someone that can take a look at it in your area.

The fault is with its main power regulator board itself. SMPS section is not oscillating. It will be best to contact any service technician. For more information go to http://electronicshelponline.blogspot.com/

Dynex dx-40L261A12 won't turn on. Red power light is on, but no sound from speakers and no picture. Remote power button and power button on tv doesn't turn the tv on.


In this case, the symptoms you describe is a faulty inverter board. The TV will or should flash "PLEASE WAIT" and then you have a black screen no audio. Find Shop Jimmy on line. Enter your TV model number. You will find an inverter board for $24.95 plus $9.50 shipping. When you remove the back cover of the TV, look to the left. You will see a long vertical board...this is what you will replace. Thanks for asking, Matt of Martins TV Repair.

One speaker buzz when cold


It works fine for a couple of minutes the starts to hum. If you turn up the volume it masks the noise but is till audible, also the video switching cuts out. after examining the components I have seen some heat discoloration in the power suply area and believe it to be power for the video board. disconecting the ribbon cable form the video board the hum goes away, and so does any video wich does'nt matter for me because my monitor1.gif does all the HD video1.gif switching. hope this may help with some noise problems.
