Have you checked your monitor? Try your monitor on another PC and check it is OK. Once you change the MB battery you effectively "Kill" the PC, as all the settings in the BIOS are removed and must be reprogrammed. You must enter the BIOS, and select "Default" setup and then reboot, you must do this regardless of what else is done first.(A bit hard when you can't see anything" You say... "tried different power switch and ribbon cable connector" (sic) exactly what "Ribbon cable/Power switch"? Anyway as said check monitor, if it is OK, we will proceed from there, then, you must check your video card, test it in another machine, if possible, to see if thats OK, if it is OK, then it is now likely that you may have a Mother board problem. If you can, try another Video card to see if you get Video on screen. see we need to establish "Known Good" items, once we know whats what, we can then go on. Now if any of these things tested are faulty, Monitor, Video card, obviously replace them, however IF they are NOT faulty, as related it may be the Motherboard, Remove the RAM, and see if anything is on screen? If yes, replace RAM, If still NO, then take any cards out, and check, if then OK, replace cards one by one until you get to the one that stops it, there is your problem, replace it. All we are trying to do is get anything on the screen, if we do, then you must redo the BIOS, as related before. Now if you get it going it still may not boot through to windows desktop, if this is the case, after you boot press F8 and select safe mode, when you get asked if you want safe mode or system restore, choose system restore and choose a date before you had a problem that should get you back. You just have to logically work through, until you find the faulty "bit" and replace it.

Testimonial: "Thanks for the confirmation!"
The fuse is internal nearest the point of where the 120VAC contacts the power supply. The fuse will be brand specific BUT will be a slow-blow ceramic (white). Replace with only the exact same rating of fuse to avoid fires within the tv.
Hope this helps and please rate!

I had the same problem with my 50HP95 Toshiba Plasma TV. It would not turn on. I read online that if you unplug a connection on my TV and it turns on, it is a bad Seine board. I could not find this Seine board anywhere online. It was either out of stock or no longer available. The TV is just 5 year old. Why would they discontinue parts for it? Then I saw a video on You Tube where someone unplugged a connection in the back of his TV to fix problem. I decided to try it. I took the back off, unplugged a connection numbered PJ63A and the TV works again. So far so good. I downloaded the Service manual for this TV to find where PJ63A was.
I also called Toshiba Tech Dept. to find out if there was a chance I can cause further damage to my TV. They had no idea.
