Having problems with your LG L1915S 19" LCD Monitor ?

LG L1915S monitor flashes on and instantly blank at boot up.

\015 Hi, I have an LG 1915S, (5 yrs old now), and up until about a week ago, it performed admirably. Suddenly, when I boot up the pc, the POST/BIOS screen flashes on and instantly goes off again, with the power light staying green. If I turn it off and on again, it does exactly the same thing. If I press the "auto" setting button, I can see VERY faintly, the image adjusting box come on, but it disappears again once it's adjusted itself.I've read a few posts on here about this problem so this morning I took the screen apart and had a look at the inverter board for any obvious signs of a fault.Everything "seemed" ok, except for one capacitor, (I believe that's what it is called). This one has a slightly domed top, whereas the others were all flat. I have the image of the board here:http://s193.photobucket.com/albums/z252/onetruecharlatan/I live in the UK and but for this very annoying glitch, I love this screen. Can anyone tell me:a). Is the highlighted part the likely issue?b). If so, are these generic parts, commonly sold in the UK?c). If anyone knows the part number, would Maplins be a likely source of it?d). Would it be easier to just buy a new board outright, given cost against cost?e). Lastly, looking at the image supplied, am I even looking at the right part as the likely issue?I'm competent at most manual tasks, (mechanics, electrics, diy, etc), so soldering a new one of these in wouldn't be too much of an issue.I'd like to thank all responders in advance for their time and help. It takes roughly 15 mins or so atm to get the screen to spring into life, turning it on and off repeatedly until it "catches" O_O, and this is growing tiresome now, but for a seemingly simple fix.onetruecharlatan.\015

I just got a monitor of exact same model a week ago from a friend, he said it got broken and he just bought a new one. It had same problem as u just described. And same thing with the same capacitor :) Soldering out the old one and soldering in the new capacitor of exactly the same capacitance and voltage (both are important, but u can go for higher voltage, not lower then required) solved the problem. Screen works great :) I believe the capacitor is 1000 microfarads and 16 volts. I have quite many spare boards in my closet, so i just found one capacitor like that on another board and used it :) But u can buy that capacitor in any store that sells electronic components. I live in Sweden, so no idea where u can buy it in the UK.
Hopefully it'll help!
Good luck
The only true way of know if this part is faulty, is put under test, with a test meter, maybe LG Customer support maybe able to help or at least guide you, anything is worth a try, especially if you love something so much, this probably won't help solve your issue but more of a direction

Monitor blank My Dell E173FP 17" LCD monitor suddenly went blank. The green power light is slowly flashing, rather than staying on.
