remember the colored wire is +, the + and - should be printed very small on the board near the connectors as well as what they are example (HDLED is hard drive LED) or (PWRLED is power LED) or (PWRSW is power switch) these are examples yours may differ slightly
Most aftermarket cd players have the following wiring diagrams (+)Red..............12v ignition
(+)Yellow...........12v battery (Memory) Constant Hot
(+)Blue.............12v Power antenna
(+)Blue/white.......12v Remote turn on
(+)White............Front left positive
(-)White/black......Front left negative
(+)Grey.............Front right positive
(-)Grey/black.......Front right negative
(+)Green............Rear left positive
(-)Green/black......Rear left negative
(+)Purple...........Rear right positive

That sounds like the circuit board has failed in the unit. you can call Parmak and see about either purchasing a replacement circuit board , or getting the unit serviced by them or an authorized service center.
OK - I'll ask the simple question first, so don't think I'm being crappy...
When you hooked the wires back up to the batteries that were replaced, did you hook them back up as they originally were? (I ran into this problem myself earlier today. I put one of the batteries in upside down and didn't have them hooked up correctly.)
Red terminal on the front battery goes to the black terminal on the back battery, then the black terminal on the first battery goes to the circuit board. Red terminal on the back battery goes to the power supply.
Hope that helps. It sure is a pain the change these batteries out.
If the devce you are referring to has K (Cathode) A (Anode) G (Gate) then you are referring to a SCR and not a transistor!
SCR are typically used in AC light dimmer and motor speed control.
You should always use the same or higher rated equivalent component: a Transistor (usually used in DC circuits) IS NOT a substitute for a SCR (usuallly used for AC circuits)!
PLEASE REMEMBER THAT YOU ARE DEALING WITH LETHAL AC MAIN VOLTAGE so unless you are familiar with both Electronics and Main powered devices, I would NOT recommend that you attempt this repair.
As a general rule, if you cannot identify what the original device was and where it originally came from on the circuit board, I would leave it to a qualified person.
Hope it helps you make the right decision.
so 6 grounds is connected together, and conneted to mains ground (direct connection), the white wires is (mains Neutral) and you connect all 6 white wires together (to doble pole safety switch) in one end pole switch, and you connect a wire from another pole the same end at common Two Single Pole Switch and connect (Black wires recess lights) to one free pole switch and (Black wires track lights) to another free pole.
The mains connect to safety switch live (Black or Brown) to another free safety switch pole, Neutral (White or blue) to free safety switch pole and earth to ground wires on mains connector.
Note: Allways use a mains 300mA diferencial safety switch, for better protection.

The red and white RCA pigtail leads is for AUX input
Left set of Preamp Outputs - Rear Channels
Right set of Preamp Outputs - Front Channels
Only Models C3433U, C3304U, and C3333U have a 2nd set of RCA pigtail leads for subwoofer output.
I just did this last week!
1 Unplug Mixer
2 Remove screw on TOP of mixer body, at back.
3 Remove rear cover and paper-gasket thing (its not the end of
the world if you end up tearing it a little).
4 the phase control (little circuit board w/wires) is at the top (you
should see it very easily) held on by one screw, remove it.
5 when the circuit board is unscrewed, disconnect all the wires
that are connected FROM THE CIRCUIT BOARD to the
black control plate (NOT all wires-there should be 4 left on
the control plate at this point). you don't need to
remember where all the colors go as the control plate is
labeled->but looking at them and making sure you
understand the abbreviations would be beneficial
(BK=black, BL=Blue RW=Red&White W=white R=red etc.
6 install new phase control (screw), either buy new thermal
grease (used to keep the board cool->it transfers heat to
the mixer's housing) or try to salvage what you can from
the old one.
7 connect wires, paying attention to labels.
8 reinstall paper gasket, then cover, then screw to hold on back-
