Power it up and the amp gives a nice thump everything lights up ok but the carousel runs and the display is blank. the toc reader z is blinking but the m led is lit on the s&cc pcb so is possible that its the problem? and could you put it right by replacing a couple of old transistors?

mayby cardridges are empty

Hello good day,sir
My compaq presario cq40..is powering on but blank on the screen and caps lock and num lock blingking only.I try ready so many time but everything are not meaning for me that's why i need your help,sir.please,give me some advice for power back.
Thank sir.

Good be a ground issue from the headunit. Try running the amp off another source (another deck, an ipod etc) See if it goes away then.

The problem can be occurred due to low voltage the adapter may be defective please confirm that the adapter is ok.

You cannot remove power from a minidisc player after you are done recording as it updates the TOC when you power down. If you had switch set to timer "REC" and power up the unit it should update the TOC, otherwise all is lost.

Without a decent Table Of Contents, your MiniDisc will NOT work, as you've found out. Does it matter what brand of MD you use? I would record it at "1X" and NOT 4x speed too. Try erasing a blank minidisc first and then shut off the unit and then turn it back on and see if the TOC works. Try adding a title, then turn it off and back on. Then try the CD to MD.

It sounds like you need to ask for pro help mate, mybe the amp just needs setting properly, Is the amp on bypass for bass, or does the amp run the complete system

Hi! The thumping motion is usually caused by faulty cross-over voltage biasing. What this is is simple; Power amps of high wattage are usually constructed of two similar but opposite polarity amplifiers ;one drives the top (positive) part of the sinusoidal and the other drives the bottom.

The simple causes that need to be eliminated are

1) Earthing :-check earthing to ensure no earth loops
2) Check the Power fuses:- usually, the supply of power to only one part of the amplifier causes thumping motion. The power section in these designs have a positive and negative polarity eg.=80V-0V-(-) 80V
3) Disconnect the speakers and check the power supply Voltages across the output stage sumettry for more details visit

if orange light blinks it will be a error installation.
