Re: Linear Garage Door Opener Control Board Repair weak capacitors
Most likely your kit is going to be the cheapest and quickest way to solve the problem.
Still, it is good to know what exactly failed. To determine if the design is bad or you just had a failure.
Also, if you design your own circuit, you then learn what the challenges are to design the circuit. It will create another type of awareness for your that just replacing boards will not do so that when you go to buy something your more aware of what is a good buy....

Re: HELP ME ! HP 15-BS572TU Restarts
Is the screen restarting or is it the operating system that is restarting? What is the sequence of events that causes the screen restarting and when it restarts what are you observing? Is there a graphic card or is it built in graphics. Most likely laptops have built in graphics. Are the display driver up to date and are they the correct drivers?

Re: Nearing wit's end troubleshooting NAD T777 v3 AVR
It will not take you long to learn how to operate and Oscilloscope. It basically is only voltage amplitude and frequency/time. Of course, when you advance there are X-Y modes and different trigger inputs. But the basic operation is simple along with the graph on the screen one reads. Calibration of the probes is also very simple with the square wave available, and the potentiometer adjust. This will open your view and understanding of what is going on in a circuit.

Re: Nearing wit's end troubleshooting NAD T777 v3 AVR
I have not been an active technician in the field for several years. With that said in order to troubleshoot a problem that the company is not willing to do to component level you would need to have the schematics, software programs and a Oscilloscope that is capable of matching the frequencies of the equipment use. For the logic side of the equipment, you would need a logic analyzer capable specification wise of capturing the voltage and frequency levels of that equipment. If a design problem, comes up you would have to understand...

Re: Car Audio Delco identification and restoration / repair
I believe the DM on the chip may stand for Delco Motorola. This could be wrong. It just would make sense to have an IC manufacturer build your ICs with your design and then put the product together with your name on it.
Some sites list the DM as Delco Modules. Would be interesting to investigate further.
The DM Delco IC are available on Ebay.

Just when buying from above people be cautious.

Re: Nearing wit's end troubleshooting NAD T777 v3 AVR
Before you go and buy the New AVR with the 3-year warranty. Read the warranty and all the ways they can escape the warranty. Make sure you buy from an authorized dealer otherwise the warranty will not be worth 2 cents. Or just buy the cheapest AVR with no warranty and gamble it is going to be good. Either way it is a gamble just depends on how much money you will want to pay for that gamble....

Perhaps you can get it cheaper at the one of the above distributors then down the local supply shop.

Re: Transistor substition
The manufacturing companies have a lot more power in getting their product to market then their distributors. If the manufacturer is not getting feedback from the customer that needs the product, then they will never know.
The reason why I said contact IT is because IT may be able to help you look up one of their products that is compatible to the SVD product. IT Products you may be able to get quicker. Many of the Mosfet manufacturers do not have a cross reference with the SVD product. I check about 3 main manufacturers including...
