Alesis Monitor Problem

Hi,

Just been reading your solution to the Alesis monitor problem. I'm having problems finding the exact capacitor. I have managed to locate a bunch of 25v 470uf @ 85deg will these be of any use?

Thanks in advance.
Mike

Hi Mate, Im no electrician so Im not 100%, basically I think it would last but it wouldnt be a long term fix as it really needs to be 105c.

Cheers

When you power on the monitor a loud buzzing noise is made and then the monitor shuts down


Hello, welcome to Fixya!

This sounds more or less like one or more bulged capacitors on the power supply board inside the monitor. Usually, excess power is what affects these capacitor most of the time.

Unplug the monitor from the wall, get a screw driver, open the monitor back cover in order to gain access to the panel/board. Look for any visible bulged capacitor. If you don't find any, use a ohm meter and continuity tester to read the capacitor and other component on the panel so that the fault can be detected.

If you find any faulty capacitor or other component, use a soldering iron to remove the faulty component, take it to any electronics parts store or visit www.shopjimmy.com

Get the exact value of the defective component and solder it back. Power should be restored after doing do.

If the above task too technical for you, ask a family or friend who has the ability to assist you. (Two good heads are better that one)....

If you are still having any difficulty, please let me know and I will respond to you.

I wish you good luck.

Regards.

Still flickering monitor Proview MA-782KC


Hello, Did you just resolder the capacitors? They need to be replaced not resoldered. When they start failing they can give exactly the type of problems you have, flickering or wavy picture, Slow display of picture when you power up monitor or very dark picture. Here is a link to an article that talks about replacing the capacitors and what you need to look for and what to replace; http://www.ccl-la.com/blog/index.php/capacitors/ If you have any questions please let us know at: tech@ccl-la.com

I hope this helps, if so please rate our solution.

Same thing.


Hello,

If you have the 2 blown capacitors on the power board then most likely yo also have blown MOSFETs and a blown fuse. The MOSFETS and fuse blow when the capacitors short out when they blow. We sell a kit with the capacitors, MOSFETs and fuse with instructions for $10.00 plus shipping. Let me know if you need a repair kit.

LCD Monitor Acer AL1717 shtting down problem


Hello,

Aside from the capacitor and IC, there's a relay that you need to change. You need to locate that defective relay on the PCB and replace it.

It would be best to consult the manufacturer of the LCD and get the exact part number of it.

Have a great day!

Alesis M1 ACTIVE MONITOR amp circuitry board is ticking


The flashing blue LED and loss of sound on the Alesis M1 powered monitor is caused by failure of capacitor C8 (220uF, 35V) on the power supply board. It dries up due to its proximity to resistor R4 (47K, 2 W) which gets very hot. This is a design fault.

Remove the power supply board (4 corner screws and 2 mains connector screws) and disconnect the two plugs. Carefully desolder C8 and replace it. Its value is not critical (220 to 470 uF will do) but it should be a 105 deg. type, preferably at 50V.

Remove R4 and replace it with a similar resistor with its leads bent so that it is nowhere near C8, otherwise the fault will return. One end may be connected to one of the existing R4 solder pads (furthest from rear of board), and the other to the top end of resistor R3. Check that you have connected it correctly by inspecting the PCB tracks.

Replace the board and all screws and plugs before testing.
