Just called JVC customer service about this issue and solved it. Step 1 unplug tv for 10 sec and then plug it back in. Step 2 Next hold down the menu and volume - buttons on the side of the TV. Step 3 Turn on the power count 3 seconds let go of the menu and volume- buttons. Worked for the LT-42EM59 model. I hope this helps.

I unplugged the TV and held the buttons down and it continued to flash. I continued to hold down the two buttons and replugged it in again and it worked. TV back up and working.

Unplugged it. After looking for a new tv online I decided to try getting it to work. So, plugged it back in and held down the power button, a red light came on, held down the power button again and an orange light came on, held down power button again and green light came on and tv powered on. This was simply a case of trial and success!

unplug, hold power button, plug in. If that doesn't work, unplug all the HDMI cables, unplug the power, hold power button, plug back in.

The power button keeps flashing


If the tv is not coming on, then you may need a new tv. If it is coming on and its just the light that bothers you, a quick fix would be to put a small piece of black electrical tape over the light. I read thru the owners manual and found no setting for this specific issue. Id suggest contacting Olevia. Hope this helps a little.

TV does not turn on? (Relay problem?)


The power supply could be failing intermittently. That's why it sometimes works and sometimes doesn't. Also, the relay could be erratic.

Black box on screen


That sounds like a text box. Press the cc button and keep pressing it. You will see different closed captions options on your screen each time you press the button. Finally when it says cc off stop pressing the button and you should no longer get the black box. If you have a cable box connected you may also have to disable the captioning on it.
