3 Beeps when I turn it on.

1) Test the voltage of machine vs the outlet wall from the house,
2) See if the frequency is 60hz or 50hz?
3) Tight the connectors very well inside, and tight any loose wires
4) Reset the machine. Turn off the c.breaker by 15 minutes, and tripped again, and Turn on again. If the problem persist you must call some service tech, the board can be faulty.
God bless you

Does anything ever post to the screen when you press the power button? if not, it's your video card. The links below are for 1 long and 2 short and they say it's the video card. I've heard that Sony extended the warranty on some models so you might want to go to their website and check yours or in a google search type: Sony GPU Extended Warranty. I did and I see they extended it from one to three years. They have the faulty Nvidia Graphics Card which was a major problem for many manufacturers.

The instructions below are copied from the programming instructions (page 11):

ERASE ALL PROGRAMMING
(The "out of box" factory default will be restored)
1. At the back of the lock, remove the screw at the bottom of
the lock housing and remove the cover.
2. Take out the battery pack and remove battery power by disconnecting
the battery pack.
3. Plug in the (provided) male shunt connector into the yellow
wire female connector.
4. With shunt connector connected, re-connect the battery
pack. The lock will immediately sound 3 short beeps (if
these 3 beeps are not heard, then restart at step 2).
5. The lock will then sound more slow beeps, 1 beep for every
second it takes to clear the memory.
6. After a few more seconds, the LED will slowly alternate between
flashing red and green--disconnect the yellow wire
shunt connector.
7. The LED will continue to slowly flash green and red for 25
seconds. To enroll Function Cards, proceed immediately
as follows:
• With the lock LED slowly alternating between flashing
red and green, present the Function Card #1
to the lock. The lock will sound 5 slow beeps.
• The lock LED will flash green rapidly. The lock is
ready to enroll the Function Cards.
• Re-present Function Card #1 to the lock. The
lock LED will flash green then red, with two beeps
(indicating the card was enrolled successfully).
• Present Function Card #2 to the lock. Again, the
lock LED will flash green then red, with two beeps.
• Continue to present, in order, Function Cards 3-
9. Each time a new Function Card is presented, the
lock LED will flash green then red, with two beeps.
After the 9th Function card is presented, the lock LED will flash
green twice, sound two beeps, and will then remain silent,
ready for use. Note: If the lock continues to beep after presenting
the 9th Function Card, check to verify that the yellow
wire shunt is disconnected.
Note: If you only wish to use the first 3 Function Cards, simply
allow the lock to "time out" after 30 seconds.

Good luck-and please provide feedback if this helps!

Annoying! happens to us too frequently, but this works. We ended up buying a new one and returning our broken one after owning for three months From Manual:) 5. Turn on the Nursery Unit using the On/Off switch on the side. The green power light should come on. 6. Within a few seconds, the Parent Unit will lock on to the Nursery Unit and the top four (4) green LEDs will shut off. A second later, you will hear a series of beeps and the connection LED should change from red to green. Your monitor is now ready for use. 7. If the top four (4) LEDs do not shut off, power off the Parent Unit and the Nursery Unit and repeat steps 4 and 5 above. 8. If the connection LED on the Parent Unit does not change from red to green and the unit begins to beep, press the channel "ch" button on the Nursery Unit. Within a few seconds, the Parent Unit should lock in on the Nursery Unit and the connection LED should change from red to green. You may hear an audible beep during this process. 9. If the Parent Unit is still unable to lock in on the Nursery Unit (connection LED will be red and the unit will beep), power down both the Parent Unit and the Nursery Unit. Wait for 10 seconds then hold the volume down button on the Parent Unit while pressing the On/Off switch. When the unit powers up, you will hear a single beep and all of the soundlights will illuminate. Release the volume down switch and within 2 seconds you will hear two beeps and all of the Sound Light LEDs will stay lit and the bottom LED will be red. 10. Repeat steps 5

turn it on then push the joystick forward till it beeps then pull it backward till it beeps then it will unlock. chair is in lockout mode
