Got the part from Mouser Electronics and cost almost $including the part and shipping. Find the correct TV part for your TV and more at ShopJimmy. I am having the same problem with my magnavox hdtv.
TV power light will not stay on or green it keeps blinking back to the red button. Light blinks green twice tv has been cracked however.
I turned it on but no picture comes thru except the digital television overlay.
Troubleshooting–I disconnected the IR Sensor the light stopped flashing –installed new IR Sensor and the TV turned on.
Magnavox LCD TV Power Light Blinks Fix - Duration: 12:45. No light goes to the power switch at all. I only use this inch HD TV occasionally. Green light flickers, sometimes turns bright green, sometimes light green, goes out, but eventually the tv will come on and it stays on and works great until next time. My solution was just to replace the entire board and the same thing is still happening.
When turning it on the power button will begin flashing for several minutes then go into standby mode or turn completely off but will not power up. I do have the blinking twice then break lights like mentioned in this post. My problem turned out being the diode ZD906.
Chirping was still present along with flashing red led in sync with the chirp. I actually turned compressed air upside . I can use the remote to power the tv on and off. There are two possible solutions.
First, you need to check your current filmware in the MENU features. Go to the Philips website and download the current filmware by following the company instructions for installation using your USB. Check your power switch on the TV it might be loose. Sometimes loose connection might . If you hear Beeping, it is the Main Board.
Common LED and LCD TV Troubleshooting. From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. I checked to see if there were any trouble codes given by the number of flashe.
Capacitors and none of them have gone bad.
