        Okay.
        Don't buy those $10 PSU "specials". They fail, and they have taken whole computers with them.

            Hmm--

            As I said before, Ive been repairing all this crap when sets still had Valves (Tubes) in and LOTS of High Voltages--Everywhere on Live chassis, with Lots of Hot glowing bottles, waiting to burn ya!

            --Proper Electronics, not like this silicon low-voltage solid-state, ipod and plastic crap we got now.

            NEVER Ever did I wear Rubber Gloves while doing so! IF Any junior tech or apprentice had even Hinted at using Rubber-gloves to work on summit--They would have been shoved out the back-yard in the rain for an hour!

            --Getting shocked--was all part of the learning in those days Heck--We used to leave charged caps around on the bench for 'em to pick up--They only ever got shocked once, never picked up a cap in such a way to get shocked ever again!

            Before Ultrasonics--How Else would you determine if a cow was pregnant quickly, Other than shoving yer hand up its ass--Have you Never seen 'All creatures great and small' about a 1950's Yorkshire veterinary....?? (Guess not--You're young--and American!)
            They were always shoving their hand up some poor cows ass in that!!

                                    Pioneer RM-07 Active monitors cutting out from time to time
                                    by BigOof
                                    I have a pair of Pioneer RM-07 monitors that I bought a while ago. When I was testing them I noticed that one speaker would cut out and I thought it was just a bad cable connection. At the price they were being sold for I was willing to take a risk on them. However, 6 months later and the one monitor still has the same issue. Most of the time it works, but there are times that the power LED is on but I get absolutely no sound. I can hear the relay clicking on/off sometimes and then it will/won't work depending on what it feels like. I've tried XLR and RCA inputs with the same issue. There's no...

                                    Hi,
                                    I built an AMD PC and I have GTX 1070ti graphics card with only 4 outputs to 4 monitors, I want to connect 2-3 more monitors, what are the cheapest options do I have?
                                    Thanks in advance.

                                    by capsulej
                                    I have a bunch of these monitors that all seem to have the same issue with bad inverter boards. Either the monitor will power on and not display a picture or it will display a picture for 2 seconds and then shut off. I know this because swapping the boards out with a working unit fixes the problem.

                                    Apparently this is caused by the dell soundbars overloading the monitors power rails as they are of poor quality. I would like to fix the boards if possible but im not sure what to look for.

                                    Hi & apologies if i have posted in the wrong section .

                                    Is there a way i can view all of the threads started by me in one place , without having to search for them , or scroll through the other posts ?

                                    Reason i ask is that sometimes i need to update a thread weeks after initial thread created due to time delay in waiting for spares from China , or lack of info at the time of posting .

                                    Within a few weeks thread would have long disappeared from the fist page .

                                    Thanks Zen

                                    Giving away parts from otherwise cracked monitors/TVs: Does anyone know a group/forum
                                    by spartantravis
                                    Hi Guys
                                    I was just taking apart an old Medion 24inch monitor that had a cracked screen. I needed the PMMA sheet inside but I am left with the working electronics, bezels and frame. It seems a waste to just throw it out considering the extortionate prices that some vendors charge for replacement parts.
                                    At the same time, I dislike the commerical aspects of selling stuff.
                                    Does anyone know of any group where people who repair monitors/TVs trade/donate parts to each other?
                                    The monitor is an MD 20830 23.8inch. The owner left it face down while moving stuff and somehow cracked...
