That depends if you have skp out or a head phone jack .If so the RCA out jack would
have to go to the input of your amp.

or the head phone jack could directley
drive a small set speakers , the 1/4 or 1/8
head phone jack plug wire from a old
pair of head phones would be strip and
wired to small external spk , or driectly
to the auido amp But keep the volume
on the Rock Ola very low if you
chose the latter ,as not to over drive
your amp.

SOURCE: My inspiron won't power up. Only green light on

There are a few things you can try. I've had similar problems like yours and went through the whole tower but it ended up being a currupt drive. You say that it won't power up, but is the fan on and the hard disc spinning. If they are you may find you have a corrupt hard drive.
What I did was remove the hard drive, connected to another pc via a adapter cable and opened it up from my computer. I backed up what i needed and then formatted the drive. Then returned it the tower and rebooted and reinstalled the operating system. It has been running fine ever since.
There are others that will recommend different ways, but to me it was easier and i lost no data and my pc is like a new one.

Try remove the battery and unplug it from the AC. Hold down the power button for 35-45secs. plug AC back and see if you can power it back on. If not, the motherboard is shot.

Be sure needle did not get damaged.

My Rock Ola 100cd "Nostalgia" Juke Box has a problem: the cd will not turn at all when it is placed on the 'turn table' by the arm. I cleaned the piston on the grabber arm which was not picking up the cd....


Check that all the voltage indicator lights are lit on the power supply, and check the connectors going to the player to be sure they are tight. Otherwise may be a bad player.

Colby tv will not power up


Hello,

The power supply converts the 120/230vac 50/60Hz into DC, then the high frequency (50~100kHz) switching circuits convert it back to AC but at high frequency which allows the power supply to use smaller and much lighter weight transformers (Ferrite core instead of heavy iron core), then this high frequency AC voltage is fed to the rectifier Diodes to get the DC output and filtered by DC filter capacitors that must have low ESR (Equivalent Series Resistance), if general purpose electrolytic caps are use, they will fail within a year or less due to high ESR.

The power supply has Standby 5vdc (5VSB, this is a MUST have before anything else will work, when this voltage is not present, there will be no any indicator light on the front panel) which is always on the minute the TV is plugged into the AC outlet, so it is on 24/7 and that is why the power supply will fail even though you may use the a TV not very often. It will see all the voltage spikes and surges 24/7.
This 5vdc is used to power the Processor and the Infrared remote receiver module which will be waiting for the command from the remote control or from the power switch, when the Power on command is received, the Processor will send the turn on signal (3.3~5vdc) to the power supply module (PSON pin) to the switch on the main 5vdc for the rest of the logic and Tuner circuits, 12~16vdc for the sound amplifiers (mostly Class D amplifier for efficiency and small size) and for the T-CON board (interface board between the LCD panel, some T-CON uses 5vdc, and the Logic board), and 24vdc for the Back lights inverter board (if there is no 24vdc then no back light).
Common failures:
Blown main AC fuse due to shorted out Diodes, transistors.
Bad capacitors leaking or bulging tops:
Shorted Diodes, transistors in the DC output side.

Hoping this will help to solve the problem....

Rock-ola cd jukebox bubbles wont bubble?????


They are probably made like the old Christmas tree bubble lights. These had a solution, I think it might have been calcium chloride and they were heated at the bottom end of the tube by an incandescent lamp that ran pretty hot. The lamps in your unit might be burnt out. I remember we had to tap the tubes lightly to get them to start bubbling sometimes.
