content: (On a sidenote, I'm still unhappy about the costs of most repairs being higher than buying new. Just tossed an industrial SMPS, as a replacement *new* 100W SMPS only cost me 11 EUR.)

content: Yes. SMPS, and UPS are among many that manufacturers do not supply schematics or repair information for. I suspect it is so dangerous to repair these, that it creates that situation. no one wants an injury, or worse, particularly the seller of that product.

content: By now I realise that our world is not only flat but also spinning the wrong way but I'm not well educated when it comes to law.Would you like to elaborate on the legal risks a manufacturer bears by simply making a schematic available to the end user, assuming the end user is electrically ignorant?

content: Not being a lawyer I wouldn't speculate, but certain they (Mfg's) prefer not to defend in any lawsuits.

content: Quote from: SoundTech-LG on November 02, 2021, 03:55:51 pmHaving a schematic in your b/w TV or tube radio manual was not uncommon back in the days. I'm not aware of massgraves of failed DIYers.And if it's a single voltage simple SMPS, there are actually not a whole lot of parts that can go wrong, schematics are not required to fix it. Other than (quality) components being more expensive than a new one, nothing would have stopped me

content: Quote from: Haenk on November 03, 2021, 09:15:02 amO yes the days when taking the back off an old radio, with the circuit diagram nicely placed on the inside .Now the manufacturer just use for example caps that have 8000hr working life .. 1 year .just long enough to last passed the garuantee.then it becomes landfill.Surely we have to go backwards to pluggable chips again. So the smart TV will be a little bigger. .Fixing something is very satisfying.If everyone fixed 1 item . And planted 1 treeWe would be heading into a better world.

content: Quote from: SoundTech-LG on November 02, 2021, 03:55:51 pmDanger isn’t an excuse to avoid supplying schematics to third party profesional repairmen. It doesn’t make sense that someone authorized to work with high voltage systems can’t access schematics just because the manufacturer considers that the 48V of some tracks of a PCB are too dangerous for him

content: Obiously there should be no reason to not release schematics for this harmless type of equipment.So, why are they not releasing the schematics?

content: Some manufacturers I have encountered have approved service agents who pay lots of money to be trained and approved so the manufacturer refuses to release schematics to anybody else to protect there service agents, bit like some car manufacturers these days won't release service info to 3rd parties. Practice should be outlawed as it's anticompetitive and damages the consumer.

content: It wouldn't take long to get schematics delivered with equipment.Our money (not yours or mine, the many) has more weight than any vote.My opinion isn't going to be well accepted... We're mainly talking about non vital products, just stop buying them if they don't conform to your requirements.Then I could go on about global economics and ecology for a while...
