Question about Akai MPC-4000 Plus Production Center (w/80 GB Hard Drive&Onboard Sounds)
I have an Akai Dr16 pro 16 track mixer.
It all of a sudden stopped working and we don't know why.
When I turn the power on all the lights come on and the hard drive spins up, but nothing elce happens. When it was working fine all the light would come on for a second or two and then go off. Now they just stay on.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

The only solution at this point would be to get the power supply repair since new boards are not longer being manufactured. In about 95% of the time if the LCD doesn't power up or turns OFF by itself or need to be unplug for some time to make work again; those are the symptoms of a dying or defective power supply.
I service these power supplies, for more info write to email@example.com

SOURCE: akai lct3201 power problem
I fixed my Akai LCT3201AD in about 30mins. using 3 small parts from
Radio Shack. Once I got the back off, I found the power supply board
(PSB), mine was part# MLT-169B rev1.2. I looked at the capacitors
(caps.) first, because they are usually easy to diagnose. I noticed the
caps. bubbled out on the top of the board (where all the cables connect
to it). There is 3 of them in a row, positioned between the two large
heatsinks. My guess is that the heatsinks are generating a LOT of heat
over time, because of bad ventilation, and causing the caps. to fail.
I went to Radio Shack and found 3 caps. (only had 3 in stock). The original ones were 16V-1000uF, Radio Shack only carried 35V and 50V in the 1000uF caps., so I bought the 35V ones and headed home, I removed the old caps. from the board, and installed the new ones. The 35V caps, are a little bigger, so its a tighter fit on the board, be careful. It took longer to remove the back from the TV than it did to do the soldering. YouTube.com has excellent videos on how to de-solder caps. on PSB's.
Total money spent on repairs:
$1.59 ea for 3 Caps. (part# 272-1032) $4.77
$2.99 for new soldering iron tip + $2.99
$1.00 donation for St. Jude's + $1.00
Total including tax $9.30
So for less than $10, I did a repair that my local TV repair shop wanted $575 for. Online stores want anywhere from $100-$275 for a PSB. If I get another 2 yrs out of it that's well worth $10.

If the power supply is supplying the main board with the correct amount of volts, your controller board or your on off switch panel is malfunctioning and needs to be replaced. If its the whole board your looking at a few hundred unless you can find the same tv with a broken screen and just swap parts.The on/off switch board is cheaper but you have to remove alot of interior parts to access and becomes a hastle.
thank u rate me!!!

First, You cannot resync the remote, Second the IR sensor may be bad on the tv and third, the Digital bd may be bad. The IR sensor connects directly to the Digital bd which is the brains of the tv. Also, there maybe a stuck button on the remote or the buttons on the tv.

the problem is in the power supply(they know about it good luck fighting them)but there is good news.you can remove the power supply and replace electrolytic caps,EC18,EC19,EC20 all of them are 1000mf at16 volt use 1000mf at25 volt.you can also go to shopjimmy.com enter model number you will see power supply part number MLT169B
it will be cheaper for you to replace the caps,the board cost about $80.00 from them

Testimonial: "Dale Hunter's response was completely accurate. I replaced the three capacitors that he identified. And it has been working fine since 2009. Now I have the black screen problem. Help me Dale."
