I was working on my Gateway GTW-P42M303 plasma TV for vertical line issue on the screen. I thought I had it fixed and went to test it when power from the speaker box jumped to the power switch bar and now I can't get any power to the unit at all. Any suggestions or Schematics?

Where is the fuse in the plug? I have the back off and checked the three fuses on the circuit boards that I could find and they all check ok. Where is the fuse in the plug? I have the back off and checked the three fuses on the circuit boards that I could find and they all check ok.

Hi,
Yes the fuse in your mains plug has almost certainly popped you may need to flip up a small cover on the plug to remove the fuse, a small screwdriver should do this fine. Make sure you replace it with one of the same value. If you have no spares, you should be able to borrow one from something else. Not sure of the value you will need but I am sure you have several things with plugs on.

Hi there, the fuse that I am reffering to would be in the plug at the non tv end of the power cable, where it plugs into the electricity outlet in the wall. Follow the cable from the back of the tv until you can go no further. Look at the underside of the plug, there should be a fuse under a small flap.

Thank you so much for your many and prompt replies. Still confused. The power cable into the tv has three prong female plug and the other end that goes into the wall is a standard US three prong 120V male outlet plug with no fuse? I know that I am getting power into the plug at the back of the TV (tested the leads into the TV). I have connectivity at the bypass power switch on the back of the TV (test the red and blick wires in both one and off positions). No green light indicating power to the main circuit board and test (with meter) all three pop out fuses to confirm no shorts or breaks in the (meter tested).

Thanks for any thing further. Thank you so much for your many and prompt replies. Still confused.

Ahh I see, sorry for the confusion, I am a uk resident and we have fuses lol. I am sorry but I was hoping for a nice easy fix for you (you wouldn't believe how many people dont think of the fuse over here.) It certainly sounds as though something more terminal has blown and unfortunately its beyond the scope of my knowledge to be able to help you in this matter. I would start by looking around the power board though, maybe you have damaged a transistor, I believe I did this to my best pc psu not so long ago but as I haven't the testing knowledge or equipment I have binned it. Not quite such an easy fix as I thought. Sorry for wasting your time. Ahh I see, sorry for the confusion, I am a uk resident and we have fuses lol.
