LCD monitor dead: diy repair?
In message
From: Mike ) "Lobster" wrote in message ... Yesterday it was working fine when I turned it off, but when I booted up the PC this morning my LCD monitor (a 15" Dell E151Fpp) was completely dead Is there anything a non-expert like me can do to repair this? Where would I start? You'll struggle to find anybody wanting to repair it. Easiest solution may be to identify all the tracks out of the PSU and guess what voltage they provided, then either break these tracks or rip all these components off the board and use a Maplin or RS multi-supply to replace it. This is not a diy job at all. Not unless youre an electronic engineer/repairer anyway. The PSU will hold dangerous voltages even when unplugged. I like the advice above of using an external psu to supply the voltages it needs - if of course the psu is that simple, but its probably not. SMPSUs frequently have feedback rails to shutdown and wake up on command, monitor for overloads etc. But being cut price puter kit it might not, I dont know. If youre lucky you might find a backstreet tv repairer to do it. I wouldnt bother with the more reputable ones, they do the same work and the price will be not worth it. If you still want to tackle it, try sci.electronics.repair. It'll most likely be a shorted pass transistor or high side chip. Not much point replacing caps. And learn how to make it safe to work on first. NT |
