HI, I recently came into ownership of this Gateway 2185w lcd monitor and it did not work when I got it. When I plug it in I get a constant blue power light like my other gateway but I get no picture and unlike my gateway fpd1975w I cannot press this power button and get the blue light to turn on and off. I have already replaced all the caps on the pwer board with theses caps (http://lcdalternatives.auctivacommer...-P1660293.aspx) I dont rember what who manufactures the caps I ordered but I know there not radioshack caps, I do know that they are black and gold with an "M" symbol on them. Either way even after replacing main board caps no pic, Im thinking about replacing video board caps but I would like some advice first before I put more money into this project.

It will help if you post clear focused pictures using the manage attachment function of your boards. We would like pics like this ...

Same story, same response. It's hard to give advice without seeing what we're dealing with. Pictures would help.
It sounds like the caps you received were Panasonic FM series. Good quality, no problems there.
Note the links in my signature. I would like several pictures. Make them as close to 2000 x 2000 pixels as possible. Use Manage Attachments (below the text entry area) to attach the pictures.
First, a picture of the back of the monitor with everything connected. Next, pictures of the top and bottom of the power supply, inverter (if it's a separate inverter), and last (and most important), of the top and bottom of the signal (logic) card. While it is possible the caps on the signal card are responsible, it is more likely a voltage regulator has failed.
PlainBillFor a number of reasons, both health and personal, I will no longer be active on this board. Any PMs asking for assistance will be ignored.
Never be afraid to try something new. Remember, amateurs built the ark. Professionals built the Titanic.Comment

Re: Gateway FPD 2185w No Picture Con. Blue Pwer Lt
With your Fluke 77, measure the voltage regulators on the logic card (U15, U16, and U18). Report all the DC voltages.
There might be another voltage regulator (U17?) just above C100, but with the angle of the pic, I can't be sure.--- begin sig file ---

Re: Gateway FPD 2185w No Picture Con. Blue Pwer Lt
Yes there is a VR above C100 (called Reg 1) and its got a capacitor soldered to it, dosnt look manufacture installed. Anyway I measured the measurements by A= top and bottom B=Bottom and Middle C= Middle and Top prongs on the regs.
Reg1 A=5.08V B=3.29v C=1.795v
U15 A=3.27v B=1.803v C=1.472v
U16 A=5.08v B=3.29v C=1.795v
U18 A= 3.26v B=1.806v C=1.457vComment

Re: Gateway FPD 2185w No Picture Con. Blue Pwer Lt
Okay, now for each voltage regulator, list the part number. The part number will tell you if the voltages are correct or not. For example, the suffix in a part number like AS1117-33 denotes 3.3V DC output. AS1117-18 would denote 1.8V DC output.
Your voltage readings look okay because most voltage regulators output 3.3V, 2.5V, 1.8V DC. However, you must compare the output with the part number to ensure it is 100% working.--- begin sig file ---

The underside of the power board is the first pic.
Here are the Pics of the underneath of the inverter/logic board.( 4 pic)
and a pic of that suspicious cap.
and no typo's U15 is putting out 3.3 though.

Re: Gateway FPD 2185w No Picture Con. Blue Pwer Lt
Maybe this will make it easier. You wrote
Reg1 (FS8860 33PJ0072) A=5.08V B=3.29v C=1.795v
U15 (AIC 1084-33PM) A=3.27v B=1.803v C=1.472v
U16 (LD1117A L18ASJ)A=5.08v B=3.29v C=1.795v
U18 (LD1117A L18ASJ) A= 3.26v B=1.806v C=1.457v
Look at U18. L18ASJ implies 1.8V DC output. B=1.806 which is correct.
If the part number for U15 is correct, the voltages for U15 are way off. Same for U16. Now do you see the problem?--- begin sig file ---

OK, you were corect on the typo[

the correct mes are
Reg1 = 3.29
U15=3.27
U16=1.18

I havent replaced the caps on the video board and I have some Saxmon 470uf 25v's i can put on to test that I stripped of another moniter, the ones I would be replacing are 470uf 16v and I cant tell who makes them but there logo is and H and it green with black strip.Comment

Picked up this Samsung above thinking it'd be backlights but it isn't. Now MAYBE I'll get lucky.
Found some shorted caps among the panel boards. Each cap along the line is shorted. On every board (3 panel driver boards)I disconnect each side right and left ribbons and they are no longer shorted caps and have about 1.5Mohm resistance (on left and right boards). The middle board has the main board disconnected and the caps are shorted. Last 4 pics show arrow to caps.
Now what exactly do I need to do in order to attempt to fix this issue?

Hi there,
i am at the present struggling with an iPhone 13.
Can someone tell me the values of the three caps marked in the picture close to Pin 1?
They are caps or am I wrong?

Hello,
First, I am a complete noob with high voltage stuff. I'm learning, but I need help by someone looking over my shoulder.
I recently came into posession of a Heathkit IO-4205 5MHz Dual Trace Oscilloscope. The documentation is copyright 1978. I'm told it works.
I opened it up to check the caps before I applied power, and found the following black caps and wanted to know what they were. They are on the power supply board. I was able to read the name and model and came up with, "Nytronics 162J-1, 0.1uF, 20% tolerance, 2000VDC."

Hello!
I have two projects on my work bench. One is a friends dead JBL Xtreme speaker with a blown voltage regulator and corresponding bulged and shorted cap. That cap has clear markings so I know what replacement I need for it.
The other project however is a whole different deal. It's a Zoom 9000 guitar effect from the 90th that has developed a devil hound howl when there is no input from the guitar. I'm guessing caps problem. So, since I don't really use this effect anymore I thought it would be a perfect project to learn on.

Normally, I never post repairs this quick after I do them, because… I am usually very slow.
But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. 
I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...
