You need to take it to the shop and get the switch replaced. It shouldn't cost more than an hour's labor/bench charge and the cost of the switch. Depending on your market probably $75-100.

I have same problem

Hi mreuten44,

If the unit won't play or read disc, it is often caused by the lens. The easiest way to correct this problem is as simple as the lens may need cleaning. Here are several troubleshooting steps that you can take:

1. Remove excess dust from the CD player. Make sure to dust in between buttons, knobs, power cord(s) and audio-out ports. Note: use a dry duster, as moisture will harm your CD player further.

2. Use a disk-based lens cleaner to remove ground in dust or dirt from the CD player's lens. These lens cleaners look like a regular CDs, but have specially-made bushes on the reverse side that gently remove excess dirt from the CD-reading lens. Simply put the CD in your player, and press the "Play" button to clean the lens. Do not run the cleaner more than once, as excess brushing can cause scratches on the lens.

3. Polish the lens. Use a glass or eyeglass cleaning solution and a lint-free cloth to gently polish the reading lens. Clean it by using a low amount of pressure and softly polishing the lens and its surrounding area using soft, circular motions. Do this for about a minute or two and then allow the player to sit for a few minutes before trying to play a CD.

4. Make sure the slider that the lens is attached to is all the way back to the platter.

5. Check the platter, it may have slipped down to close to the lens and it wont focus.

6. If the above steps did not work, the motor drive circuit is defective. At this point you need a help of a repairman to check the unit.

Hope it helps.

Thank you for using FixYa.

A call to Gemini is in order here. Given your location, try asking if they will send you a replacement drive. It is common for the drives to contain special uncoding that will prevent a generic replacement drive from working properly. Since this unit is so new, it is likely that the company will replace the drive for you.

One of the first things a technician does with a voltmeter it to check 'all the voltages' in a system are correct.. Even without a specific circuit diagram for the board, 'Applications Notes' for chips and seminconductors will give nominal expected voltages in a working circuit. Remember you can burn out the meter by connecting it to any source of current when on the Ampere or Ohm settings. Technicians usially start at a high (highest) Voltage range setting and work downwards.. Providing the maximum Voltage is not exceeded on any range, whether it is AC or DC will not damage the meter. 'Fluke' by the way are a 'top end' professional product - check the price ;)

The most likely case is that one of the main output transistors (if which there are many) is shorted. When the protect circuit senses DC on the final output, it will not allow the output relay to come on to protect the speakers from raw DC. With the power removed, you can check between each outputs Emitter and Collector and you will probably find close to zero ohms. From that point you need to unsolder each of the pins of the bad channel until you find the shorted device(s) and replace them.

Depending on the model, there are four around that date, it could be the insert jacks are tarnished reducing the signal flow between the pre amp stage and digital power amplifier. It could be the power amplifier has failed. It could even be customer error in wiring. This assumes there is the correct level of signal entering the input sockets of course.
