Hello,
This might be a board with a loose connection or a faulty capacitor on the power board or one of the immediate circuits attached to the power supply board. I would suggest that you have this serviced by a qualified TV Technician. However if you wish to do this yourself, you need the following equipment:
1) Multimeter (to measure the voltages; AC and DC on the various test points on the boards)
2) Oscilloscope (to measure the startup and shutdown circuit ramp voltages)
3) Isolation Transformer (to isolate the Tv from the AC circuit that the test equipment is on)
4) Service manual or schematic diagram (to show where the test points are and what signals and voltages to expect)
5) Signal generator (to generate reference signals for servicing the TV)
Now if you know how to use these pieces of equipment your are ready to start, if not again I would advise you to have the set checked by a qualified TV repair technician.
I hope this helps
Thank you,

its a circuit board problem.it has to be replaced.to resolve the problem.but the circuit board is very costly issue to repait.it will cost you near to new machine.
but still your choise.you can get the board replaced or .......!
thanks
it is defenitely a power problem some of them have internal resets and you should check. also you could have a malfunction of the power supply module on the circuit main board. if there is no reset then i suggest that you take it to a aplliance repair shop and have a tech replace the circuit module.
I believe whoever sold it on eBay did so for a reason....it's broken. I just bought a Breadman Pro at Linens n Things for 79.99 with the 20% off coupon from Bed Bath and Beyond (those two stores are interchangeable) and I have NO problem turning it on and have successfully baked several loaves of bread without incident. I'd suggest going and buying a new one. Sorry.....
Don't try this unless you know what you're doing. But, if all else
fails, give it a shot. I tried the fixya solutions, but none of
them worked. Since I still had power to the light when I opened the
lid, I assumed it was a problem with the keypad microprocessor. With
the breadmaker plugged in, remove the ribbon cable connector connected
to the PCB board. This will short the pins leading to the keypad. You
might have to touch the connector to the pins on the circuit board a
few times to make the microprocessor go "wacko" and reset itself. Once
you hear the beep, the display should be working. If the convection fan
or motor starts running while trying to get the display to work again
just hit the reset on the keypad and choose any cycle and hit the start
button. It may take 30 seconds or so for the machine to reset itself to
normal operation. If anyone knows which pins to short out, I can solder
in a reset button, so if this ever happens again I won't have to open
the control panel. Or maybe the keypad needs to be properly grounded.
I have a cdf-e75 that had a similar problem, although the red power light was dim for all functions. (the radio, tape and cd)
After opening up the unit and inspecting, I found one of the pins on the printed circuit board for the power had broken away from the solder. (it is a tiny board where the AC connector is soldered to) Seems in my unit there is nothing securing the molded AC connecter to the plastic case except the the printed circuit board it is soldered to-It is a poor design; perhaps your is the same? I suspect over time pushing the AC cord into the back of the player may have broke the connection? Anyway, I soldered the connection and I have never had any additional problems as the unit has worked fine since.
Don't know if this helps, but my suggestion would be to open the unit and inspect the pin connections on the AC printed circuit board to see if any have a loose/broken connection. ( Mine was not noticible with the naked eye as I had to use a magnifying lens and a bright light. Hope this might help.
