Abdi I can see two solutions:1. Get a right-angle plug to go in the power socket. You may be able to buy a suitable 12V power supply with such a plug on it - no soldering. Or you may have to cut the existing plug off the power wire and solder a new one on - you should be able to buy one at any good electronics shop, take the power supply with you so you get the right thing. Make sure your new plug has the right polarity (+ and - in the same places as the old one. You'll need a meter for this, and soldering skills. Google "right angle dc power plug 2.1 mm" for some possibilities, but your plug may be a 2.5 mm type - this is why I suggest taking the power supply with you when you buy one.2. You could remove the board and unsolder the power socket and just solder wires in instead. This is a LOT more work and unless you are careful you risk breaking your TV. Only do this if you can't use solution 1!
