Re: Iiyama Prolite E431S Turns off

Good news, and thanks for letting us know. I'm glad to have helped, but I certainly wouldn't have figured it out without help from the other members here....

Re: Iiyama Prolite E431S Turns off

Thanks to these forums I was also able to fix my Iiyama Prolite E481S.
On the basis of the previous post I replaced the four transistors by the inverters and replaced them with C5707s (NB: mine had to be soldered at a 180 degree orientation compared to the existing ones - D1691). This did not fix the blinking blue light, so I took another look at the board and realised I'd missed the obvious: 2 x 1000uF electrolytics that had bulged and leaked. Once I'd replaced those two it kicked into life. I believe they were branded NRSA, so not sure...
