I have got this 17" TFT, the power LED was green, but no picture. Just after powering up, the screen flashed up and then was black.
After opening the case, i saw a PSU full of Lelons. One of them already showed severe bulging.
I replaced them and the other major caps on secondary side for wich i have had appropriate replacements there. (a few 1000uF / 16v, 1000uF 10v). A few 470uF 16v ones i had to leave, as i haven`t had replacements.
Primary caps are on big 400v cap, probably an Nichicon PS ( not shure abouth that, as it was glued to the PCB with the labeled side down), a few 10uF 50v Nichicon PS and a few Lelons, wich i ahve not replaced yet.
The display is now working again flawlesly. The whole thing was bout 4 to 5 years old.
