Have to hit the on button several times before it turns on. each day it takes a few more times before it comes on. works fine once it is on.

Power button may need to be replaced. Try turning on via remote.

Some TVs need to warm up before coming on. Hitting the power button several times may in all actuality be Turing it off and on.

Hello, that seems to be a bad contact on the enter button, the solution is to take a part the key and clean it, otherwise you need to replace the under key switch.
Thanks

I had come home about a week ago and pushed the power button from my remote but my tv did not respond. So I just went to the front panel and pushed power but once the tv turned on, the volume was on full blast! I used the front panel volume decrease to get the volume down, but when I stopped pushing the button, the tv increased its volume to full blast again by itself! Naturally I just turned the tv off for a few moments. I tried the remote again, no response again, so I used the panel power button. The tv volume was still full blast when it turned on but after I decreased the volume it stayed this time. The picture is and has been perfectly fine and the tv was working fine. The next day the problem started all over and now once we turned it off from frustration of having to manually use the panel to change channels, it now will not turn on at all. I have changed batteries from my remote, reprogrammed my remote, pushed system reset several times, unplugged it for a while, bought a new surge charge, and even held the menu and device panel buttons for 10 sec and tried to turn the t.v. on again! What other options do I have or what may be the issue at hand and possible parts that may need to be replaced?? Thanks!!

I had the exact same problem on my unit the other day. I spent a couple of hours trying to fix it. Did the reset button button behind the faceplate and the I couldn't get the unit on at all. I found the if you push the power/source button as soon as you put the unit on the power would turn back on, but buttons still wouldn't work. After trying several different combination, I started hitting the UP arrow button (which is the program buttons) as fast I could for about 10 seconds and the unit started working. Might have been lucky, but it worked for me.

If its an duplicate bulb it will take time to arc

it isnt the Y-SUS board, it is the Power supply, iv fixed this exact problem twice in the last month, try turning the tv on, and when it turns green, unplug it real fast, while light is still green, after 15 seconds plug it back in, then hit the power button, if it dont come on, hit the power button again, this time, as soon as it turns off, hit the power button again to turn back on, sometimes you can trick the tv and it will turn on, at least i was able to do it, and once it comes on, it should work fine, untill you turn it off again.

try starting in safe mode then when it windows starts/full loads shutdown the computer. Then restart the computer-it should start normally.

time for a new tv

got it thks
