content: Hi I have a Parkside Dual 20v battery charger and only 1 side is working The only difference I see on output when turned on is on the 3 charging pins [ + 1D and - ] is between the - and 1D is that on the working side there is 5v and on the non working side is theres no voltage have changed 3 conponents Q1A [ 12N60 ] and D5A [ MBRF 2015OCT ]on the heat shields and U3A optocoupler DIP4 PC817 but no joy can anyone point me in the right direction. Thank you John

content: Hi, welcome to the forum.Just before you start on that board, remember that those products have a 3 year warranty. I can't remember how long the dual version has been available but it may well be returnable.

content: Hi John.Of course see whether warranty is still valid.Lidl doesn't have technicians in their stores, so they won't bother replacing appliances unless there's clear evidence of tampering.Be aware that there is live power when plugged in so there is potential danger.That's one circuit, times two and the PCB they are mounted on isn't cut in two to get 2 single chargers.You have one functional and one non-functional charger, which means you have a defective one which can be compared to the functioning one as a reference.Divide the PCB into virtual blocks.The first thing i would do, is to check if there is power from the rectifier, the outer wires are lead to the DC part.Is there any voltage there, and are the voltages equal in both sides (under the same conditions, so batteries to be charged in both slots)?

content: Hi thanks for replying bought it second-hand so warranty isn't an option and have tried to compare both sides and seem to get 20v at middle leg on d5 on working side but nothing on non working side seem to get 10.4v on either legs on both sides from memory that's by putting meter on neutral and positive on one of d5 legs????not sure if I'm testing rightWill take another look tomorrow night

content: Right while having another look I blew the 1R8 smd resistors and not sure if the KBP310 bridge rectifier was already blowen I took that out as well not sure that might have been the original problem but will replace these parts and will update but it will be a week or so but will do an update then. Thanks for any other info

content: Be aware that the rectifier goes into a beefy capacitor which would result in about 325 volts DC (in case your grid also has something close to 230 VAC), it would be a nasty sting !

content: Thanks👍 , yes it's 400v 68uf got hit once by a camera capacitor it's a right shock know to stay away from those capacitors wasn't expecting it in the small camera obviously it's for the flash👍

content: Just an update no joy probably did more damage than good when I short circuit the smd's maybe theres undercircuit layers damaged But Thanks for any help.

content: If it helps, Lidl got them in last Sunday. I can't remember the price but they were pretty cheap. The single 4.5A version is even cheaper. They are almost invariably cheaper in store than you can find on ebay (working). Should be some left.Edit: £20 for the dual.
