Good thing i did since after i removed the caps i measured them using my cap meter on my fluke Originally Posted by chomot Post I know this is an old thread but I figured since there is good advice here on the P I should see if my problem will add to it.

There appear to be 6 pins on what i would call the primary side. Should ALL of the inputs on the primary side be shorted? Have you seen this before? If the bulb light and daatasheet goes off suspect a shorted winding and if the light goes off, the winding is ok.

A good method for checking a monitor with black screen and no power LED is to check the power supply outputs; typically 5V and 12V but this can vary. Show 40 post s from this thread on one page. Originally Datasheeh by Welchs thanks!!!!!! They were the SAMXON brand which i remember reading on here that these were “bad” so i replaced the other caps as well.

It did not work out, still have the same issue. I replaced this cap. Originally Posted by Welchs SO this leads me to ask the question Does anyone know of any issues with these.


If that does not satasheet I will ask if anyone wants a monitor for parts or repair as I will be outa my leage. One end to datsaheet circuit while dxtasheet other to the transformer pin. If it is missing, check the fuse, etc. I see no obvious issues visually. SO this leads me to ask the question Originally Posted by Welchs You really think the burnt spots are just due to bad solder joints?

That typically has at least 3 different voltages, produced by bucking regulators.

ALL 6 pins are shorted In the areas that are burned i see this chip. Using what fatasheet guys said i started probing around.

I will get back to you with the results. I know this is an old thread but I figured since there is good advice here on the P I should see if my problem will add datashret it. Measuring the primary side of the transformer. Since I am a one trick pony on these I orderd datasbeet set of caps and replaced them hoping for the best.

So i guess its ok. I looked into the fuse and connector advise and could not find any issues. I am not an electronics wiz, for this issue I am more of a one trick poney. I did reflow the transformer connections. But i cant seem to find a datasheet for this chip.


I have fixed about a doz monitors now with only the knowledge of replacing the PS caps and have had good luck with this as I have always found the bulged caps every time I opened one up. Can you tell from the data sheet if D2 and D1 are shorted? All it is is four buttons and an LED. I am thinking the power supply card is fine but the video processor board is acting up.

Thanks guys and thanks BAd-caps forum. When i take a meter and measure the resistance from D1 to D2 i get a short It will since the presence of a video signal when I switch the note book PC I use for testing from onboard LCD to external and back but that is all it dtasheet other than make a nice large square desk light.

Could it be the transformer? I guess I will replace the four uf x 25v, two uf x 25v and the one uf x 25v and see where that takes me.

Sorry for the long lead, I am have some time now to get back to this. I started with the voltage across the big filter cap Anyway this one has the good brand of Samxon for all but the big guy and that is a KM M but they rarly go bad from what I know.
