    • Best to do this with the screen facing down so you don't rip out the ribbon cable that attaches to the buttons on the front of the screen, start in the middle of the bezel to get purchase then slip a screwdriver underneath to gently prize up the bezel working along until its released, the edges are stubborn but do release with patience

    • remove the 4 screws one is bigger than the rest then undo the screws that hold the power cable socket in place, once the power socket screws and the top board screws are removed put your thumb over the power socket and pop the board out sideways you don't need a great deal of force to remove the PSU board just loosen gently

    • take note of the berg strip and make sure you don't damage the pins when removing flip the board over and you're ready to remove the capacitors, when re-assembling make sure the berg strip lines up correctly before pushing the boards together

  9. Repairing LCD monitor Dell 17", This is what a successfully repaired monitor should look like: 9 단계, 이미지 1/1
    • After re-inserting the ribbon cables a small one for the buttons at the front of the bezel and the main one that carries the data to the display, once you have reconnected successfully you should get a clean bouncing screen saver moving around the screen, if there are any screen anomalies it is always the thicker data cable that needs reseating

  10. Repairing LCD monitor Dell 17", Put the back cover back on: 10 단계, 이미지 1/3 Repairing LCD monitor Dell 17", Put the back cover back on: 10 단계, 이미지 2/3 Repairing LCD monitor Dell 17", Put the back cover back on: 10 단계, 이미지 3/3
    • it's best to test the monitor before you put the back cover on the screen, as invariably the larger of the two ribbon cables has not seated correctly, once you're happy your screen works put everything back together and you're good to go

결론

Reassemble in reverse order taking time to re-fit the ribbon connector which can be a bit fiddly but you can test it

Thanks for this post! I am having an issue with the VGA input on this monitor. The monitor turns on no problem, but doesn’t get a signal from a VGA input. I have confirmed that this is an issue with the monitor and not the cable. Will this resolve the issue?

Yes this resolves the issue

Derek Brabrook -

This fix is specifically for the issue where the monitor switches on and has a green light on the front but there is a black display OR it can manifest as the display briefly coming on but then switching off and staying off after about 2 or 3 seconds

if it’s your vga logic board then see Step 7 that logic board is the one to the bottom left of the picture with the ribbon cable attached that is the board that deals with the signal coming from the computer VGA output, if you remove that board and heat an oven up to around 180C and put it in for no longer than 8 minutes with the components face up enough to reflow the solder then remove from the oven (carefully because any sudden movements could dislodge the components as the solder will be liquid)

that may fix the problem, no guarantees mind that’s a last ditch thing to try if all else has failed…

hope that helps :)

let me know how you get on :)

Fantastic really appreciate the reply! Will have a look at what you have said and keep you posted :)

Gary Ogilvie -

I honestly don't know where the other editors of this guide sprang from, none of them contributed to it, most of them removed things that you'd need like two 470uf capacitors and they'd remove one capacitor, this circuit board always blows both capacitors, or very minor picky changes….

I wrote it as I intended it to be read….

So if you don't know what you're talking about don't edit my guide when I know its 100% correct

Thank you!!!

If you keep doing it, I'll just delete the whole thing
