Hitachi LED tv 24" with DVD combo

[hernan_perez_br]

Hi all, I am having an issue with a Hitachi LED Tv 24" with DVD Combo.
I found the DVD on the street with looks in mint condition but obviously is not working so I decided to give it a try.
It is a model le24ecd05au, the power rating is 12v 4A, I do not have a 12v 4A transformer but I connected a 12v 1.5A transformer and I plugged in the TV
it shows an standby red light and when I press the power button it shows a blue light (power on light) but I cant see any picture or even the Hitachi logo.
Initially I thought it could be because I am using a 1.5A transformer and the TV does not have the power to power on. but I tried pressing the "eject" button
of the DVD and the TV powered on, showed the Hitachi logo and power on, I could see the menu, etc, all fully working. I inserted a dvd, etc and it was working.
Then I power off the TV and I could not get it working again, the eject button did not work anymore, I have to dissasemble the tv to eject manually the DVD.
Do you know what could be the issue with this TV? I think it is not the PSU because it is a 12v TV.
Any help will be more than welcome!

There is a reason it is rated at 4 amps. You cannot be sure if a 1.5 amp supply will be able to supply all the current required, for example during eject it might draw an additional amp of current to get the eject motor turning.

Hi thanks for the reply, yesterday I used a power supply 12v 7.5A, and it does the same thing. I was able to start the tv 2 times and it works perfectly, the TV, HDMI, VGA, DVD, all works OK.
but I tried many many times and only 2 times it started, all other times only the blue light is on but nothing happens on the screen.
When the tv starts it should show the blue light and the hitachi logo on the screen, but around 95% of the cases it will just show the blue light only.
Thanks !
