E50CB curcit diagram - ViewSonic E50 15" CRT Monitor

If your heater is totally disconnected wiring and breaker trips, you either have a bad breaker, or you have a wiring problem. If breaker trips immediately then the problem is the supply side wiring. Ether case I would call electrical, to diagnose and repair.

you can get the diagram with manual to fix the problem you can get the manual from the given link http://toolsnyou.com/

You can download a complete service manual on tradebit for as little as $5.00. It will have all the diagrams you need.
Good Luck!

i want ful electical curcit

For what?

Obviously there is a short circut somwhere.

Start by switching on only the park lamps.if the fuse blows you know the problem is on that curcit.

If not then switch on the low beam headlights, if the fuse blows you know the problem is on that curcit.

If not repeat this action with the hi beams.

If the fuse blows on park lamps already check the front and rear globe conectors for a short curcit. if none are found procede to check the low and hi beam globes.

check your vga/dvi cable connection at both ends, computer and monitor

Usually you can only change the device options if windows XP recognizes the device. Does it show up as a viewsonic E50cb in Device manager (My computer, Properties, Device Manager) or just as Plug and Play monitor? I would download the drivers (or if you have the CD) for the specific monitor you have and then I bet the options will open up for you the way they should be.
