My Vestax PDX-2000MKII Pro will not power on. It was working last night and then when I tried to turn it on this morning, it will not power on at all. I tried different outlets throughout the house and it still will not power on.
For anyone with similar problems and a spare working PDX then try taking the back off them both and unplugging the power-on switches (not the platter start/stop switch) from the circuit board and seeing if the switch from the working turntable works in the bust one. I have had the switch die and replaced before so knew to check this but the cost of a new switch is minimal and replacing them yourself is easy as long as you can use a soldering iron so definitely try this before panicking too much.
More than likely the power transformer fried. If so, it will need to be replaced. You might also want to check the fuse. Some of the PDX units have fuses on the rear (where the RCA cables connect)... some don't. I've also seen some that have a fuse on the inside of the turntable, underneath the turntable platter... some don't. If your's has a fuse, see if it has burned out. If so, just replace.
If not, then the only other thing that would affect power on the PDX is the power transformer, and only a qualified service tech should replace this for you.

Is it made of plastic, it is probably warped. Put it on an flat table to check; both sides. If that's not the issue, it could be a spindle bearing bad or loose.

If the fuse keeps blowing it's because some part is acting like it is a piece of wire. It will probably be a semi-conductor in the power supply of the turntable, or the transformer. They often look burnt or damaged the semi-conductors in this state.
If you disconect the wires to the cartridge you can check if the sound is getting to the amp. With the amp switched on and the turntable connected, touch each wire one at a time with your finger. You should get a buzz on one wire on the left and one on the right with another. The other two wires won't give off any buzz. If you don't hear the buzz on either channel, either the connections linking your amp are faulty or the magnetic cartridge pre-amp inside the amp has failed. If you do hear the buzz then the cartridge is faulty or the connections to it are bad.
What is the weight on the stylus? Flip the protective shield
down to protect the stylus if available. Tare the tone arm (adjust the counterweight
on the back of the arm until the arm floats perfectly level), then hold the
counterweight and turn the dial markings to read zero. If you cannot find the recommended
mass for the stylus you can use the average weight of 3g. Verify your tone arm
is still floating in the center and the arm is perfectly level. Turn the
counterweight until the dial indicates the specified weight of the cartridge
manufacture specification sheet or you can set it for 3g if you do not have the
specification
sheet.
Make sure the platter is seated correctly. Lift it off, and set it back down. Also check to see that there is no debris or foreign matter stuck underneath the platter or where the platter sits.
Check to make sure the platter itself is not bent or warped. Do this by removing the platter (lift up), and then put it on a flat table/surface. Look at it from the side. Is it warped?
Hope this helps

You have a short in your unit, and you will need professional assistance in determining the cause. You might also want to try a different outlet. If it fails, then you'll need to bring it to a service center for repair.
