I had same problem. by removing mains plug from rear of tv and reconnecting a couple of times, the tv would fire up. the couple of tmes became ten, then twenty, then forty times until it stopped working. a new power unit didn't work either. the solution is bin it and don't buy this make again.

Hi, I have a dmtech LU20xt which has built in free view and DVD player, I can't turn it on manually or with the remote, the red power light is on but nothing will happen, any advise please!!!

The inverter board is the "power supply" inside the case. The DMTECH Service website opens with a video showing how to replace a couple of capacitors on the board but I would not advise non-technical people to attempt this.

I have the same no picture but sound on a DMTECH but so far I have not opened the case to have look - I have to be in the mood.

Does anyone get answers to these Qs?

I am not qualified in any form of technology and have no idea what an invertor board is. How can I recitify this situation

I have a DMTECH LCD tv/dvd player and it's suddenly stopped working. When plugged in the standby button flashes on and off with the blue light, and not matter what button is pressed on the side of the screen or the remote control- nothing happens.
The instruction manual is not helpful and states to contact a service centre, to which there are no details of in the manual.
