[Solved] How to fix M24E14 M24EI4 power supply board

qwe1234 2,811 784 November 10, 2009 at 11:25 PM
My Soyo 24 monitor that I bought last year at a geeks deal has just died on me today.
Its internal power supply, which most likely is a problem, M24E14 great wall, is nowhere seems to be found but the taobao.com web site.
The zener ZD1 has burned out therefore likely some other components dead too.
Solved by substitution a USA made generic PSU that has required voltage.
Quote from bizcards View Post :
I replaced (adapted) the ZD1 with an axial 30V 1 watt zener diode (to prevent overheating) and it worked like a charm, just watch out for polarity when replacing it. I also replaced a couple of bulked top caps under one of the heatsink.

I hope this will help you as well

Regards

No, there is a board in between the cable and the display holded with 4 screws.
Ah, I see. If you have pictures, post them. They might help other people become familiar with the internals of the unit.

From my semi-research on LCD problems, most people seem to have Power Supply problems or Inverter problems. Looking at the control board, it is pretty straight forward and I don't expect it to have many issues ...in other words, it should last 'forever', as should the other boards (except power supply and inverter).

Incidentally, I found a site that seems to sell generic Inverter boards (which may or may not work with this monitor, but I suspect they would) for ~$140. If that board went on mine, I would buy a new monitor ...even if it wasn't as nice as the Soyo. I do like my Soyo's though.


Here is the link - it the last one down:

Spent some time looking at some of the Google translated pages and found something interesting. It looks like a site (taobao.com) offers some kinda of way for overseas folks to utilize their site and arrange shipping. I've attached to pictures (1) showing the checkout process tutorial that shows a Canada address and (2) showing that the USA & Canada are a shipping region. The site looks like an 'eBay' type site.

The starting link was:
http://translate.googleuserconten...LU2Uj_6_6g

I've added a third picture showing some customer service phone numbers/email address for this service. There is one that is a Hong Kong number for overseas customer advice.

It looks like the service is globlal B2B site. I clicked a link at the bottom that was "International Station" that took me to Alibaba.com. Tried to search for our power supply, but didn't find it.

No, I haven't gone that far. I was deliberating wether to try to setup an account or email the HK customer advice office. I haven't done either. Let me know if you try either way.

I think I set an account with no translation that let me send mesages to the sellers. I was not able to translate those pages and went by intuition as this is the field for the user name next for the password and so on.

Here are some pictures of the power supply/ control board assembly.

The small card with the video inputs is the control board. The very small third card visible in the second picture is the power switch and LED indicator.

I'm really needing this power supply also. From the looks of it on Ebay, a lot of other people could use it as well. I'm willing to pay extra for someone to secure these and resale them here in the US.

A substitution PSU works. The monitor back to normal. My concern is that the new PSU is too small for this monitor as it became too hot. Will see if it survive overnight.

Got all excited when I saw problem [SOLVED] ...glad to hear your monitor is working. I was pretty sure that using an alternative supply would yield satisfactory results. Do you have a link to the power supply you used? What is the make/model/specification?

I think you might want to remove the "Solved" part of your post, since we don't have a source for the actual Great Wall CGCPOM24EI4 power supply.

Have you heard anything back from any of the emails or phone call that you may have made?

I start to think it is not a Great Wall PSU. It has another label Front bsfp2415004a6 located behind a heatsink. I found the solution to the problem though, which do not even require soldering, that why I changed the title.

I got some spam on Chinese that ebay site sent I believe.

I put this one http://www.ipdpower.com/catalog/p...asp?id=382 but you do not need to follow. Just use anything you can get.


All monitor gets VERY hot. All the metal back of the screen can not touch, not to mention the PSU area. That probably why it breaks.

What was your solution that did not require soldering? Buying another power supply? The one linked? How much was it? I think some people will still be interested in getting their hands on the Great Wall CGCPOM24EI4.

If it is getting as hot as you say it is, it may not last very long as you may be overstressing it?
