Question about Dell UltraSharp 1702FP 17" Flat Panel LCD Monitor

Where to buy the capacitors?

Do you have any idea where i might be able to buy these capacitors?
They are surface mount and everything that i can found around here is the normal thru hole capacitor.

Which Capacitors, You need to knowthe voltage and farad rating (ex. 16V 1000uF) they are different, If I can get the schematic then I will need the component #. Are you sure that the capacitors are SMT and not "through hole" units? Usually the Electrolytic capacitors (Canister looking things) are the first to go. They will start to swell and leak causing power problems. Do you have the unit open? Can you upload a pic of the boards?

Monitor turns goes black and comes back on every 10 secs planar PX2210MW

The Planar PX2210MW is notorious for bad electrolytic capacitors. Specifically capacitor C804 on the power supply board. . This is a 1000uF 25volt capacitor. That capacitor was usually made by Hermei and it was purple. Normally, the top of a capacitor will be flat. When it fails, it will be curved upward and there may be some brown material leaking out.
If the monitor still will not work after replacing C804, the problem could be Q805 or Q806. These are located on the under side of the board. They are small black surface mounted chips. There are 8 pins on these chips. I have seen both AO4620 and APM4548A part numbers used. These chips contain a pair of MOSFET transistors. One transistor is n-channel and the other is p-channel. Look for a short in one of the transistors. I have repaired several of these monitors. C804 is always bad. How ever, in three cases, Q805 or Q806 was also bad 12c1ec2c-5a6d-4352-af31-150a0a92514c.jpg c9a53aae-2999-45c7-ad78-44ba51ac5a6c.jpg 795d93fe-9678-46c2-820a-767bea9babb0.jpg

The power supply blew a capacitor and a surface mount fuse for the 5 volt to the video board. After replacing all the capacitors on the power supply board and the fuse, the LCD will come on with mostly...

Soory for the bad news but the problem is in the T-CON board (where the surface mounted fuse is blown, which means that it had shorted out components somewhere).
Not much you can do but replacing the LCD panel since the T-CON board is intergrated with the LCD panel.
Switched +5VDC at the T-CON board is steady with no AC ripple?

Learn about bad caps:

Capacitors kit: he can make you a set of caps for you.
Or just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.

Installed new 27-D01567 power supply unit in my 19" monitor L1975nw. have green light but black screen. whats next?

Is the board brand new or used? You will need to verify the voltage (12~18vdc) feeding the inverter circuits, there is also a surface mounted fuse.

I have a flat panel lcd 19, it doesn't power on

Don't know what model you have, but I would check the fuse first. It should be marked with a Fxxx where xxx are numbers. Sometimes the fuses are glass, others times they look like little surface mount chip types. If you find that a fuse is blown, does not mean that just replacing it will solve the problem, you need to figure why the fuse has blown, typically the FETs short out. Hope this helps.

Monitor takes forever to come up the blue light flashes and flashes for a long time I read where the vl1918 needed a capacitor replacment what do you think

blackbeard1, Could be it needs Filter caps. I would also closely investigate all solder connections of surface and through hole mounted electronic components for possible "frosty looking" "cold" solder joints that may be thermally intermittant!! 12fix louie

Proview 900 series black flat panel monitor

its sound you have bad inverter chip. The I.C. "BIT3193G" is the main controller in the inverter circuit. This chips is a surface mount chip and you must be careful remove it or you can damage the board. Also have you check for any burn out transistor?

Viewsonic VP211b No Power

I have fixed several of these.
The most common fail on the Viewsonic VP211b is a blown fuse on the inverter board. Check fuses F1 and F2. These are Fast Blow 2.0 Amp surface mounted fuses, case style 1208. Available at Newark Electronics, part number 64R8010. They are located on either side of connector CN1.

Black screen

Does your computer appear to be booting?

Do you head any startup noises, or the startup sounds you hear when Windows loads?

In no, have your computer checked.

If yes, make sure your cables are all snug. Other than that, it depends on how into "fixing it yourself" you are.

Give this a try:

Open the unit and check to see if any of the capacitors in the power supply or other boards look domed or vented on the top.

Replace any capacitors accordingly. Use the same value capacitors. Most often, 1000uF 16V or 25V, 470uF at 16 or 25V, 220uF at 16V or 25V.

If this doesn’t solve the problem, try checking the surface-mount transistors on the inverter board that run the lights. Some times these transistors go bad. Check the area for any cracked or overheated ceramic or mylar capacitors.

You'll need a soldering iron, solder, solder ****** and some idea of how soldering and desoldering work.

Dell computer screen black out

Try replacing a couple of the surface mount capacitors. Start with the 10uf's C604 and C507 this will usually bring them back to life.
Good Luck!
