The Old Days
Back in the pre-computer CAD days, PCBs were designed and laid out by hand using adhesive tapes and pads on clear drafting film. Many hours were spent slouched over a fluorescent light box, cutting, placing, ripping up, and routing tracks by hand. Bishop Graphics, Letraset, and even Dalo pens will be names that evoke fond, or not so fond memories. Those days are well and truly gone, with computer based PCB design having replaced this method completely in both hobbyist and professional electronics. Computer based CAD programs allow the utmost in flexibility in board design and editing over the traditional techniques. What used to take hours can now be done in seconds.
PCB Packages
There are many PCB design packages available on the market, a few of which are freeware, shareware, or limited component full versions. Protel is the defacto industry standard package in Australia. Professionals use the expensive high end Windows based packages such as 99SE and DXP. Hobbyists use the excellent freeware DOS based Protel AutoTrax program, which was, once upon a time, the high-end package of choice in Australia. Confusingly, there is now another Windows based package also called AutoTrax EDA. This is in no way related to the Protel software. This article does not focus on the use of any one package, so the information can be applied to almost any PCB package available. There is however, one distinct exception. Using a PCB only package, which does not have schematic capability, greatly limits what you can do with the package in the professional sense. Many of the more advanced techniques to be described later require access to a compatible schematic editor program. This will be explained when required.

I just bought a payphone on ebay, advertised as new, but it does not have any info with it and I do not see anything on the phone showing make or model. Seller says he does not know either. What do I do...

The guts of smartphones were made by 2 companies, Elcotel and Protel. Here's a link to the website. Perhaps you can match a picture of the phone and download a set of instructions.

Dynex 32" tv picture goes black

If there is still about ? 24. Volts coming from the Power Board when it goes dark, it will be the Inverter board that needs replacing. If not, it is the Power Board that needs replacing. The Voltages should be written next to the sockets & plugs on the Power Board.

Bought it in 2008, now it comes on for 90 seconds then goes out. Probably a bad inverter or power supply board. Are parts available for this monitor?


Is it the screen that goes blank or the power of the monitor? is the power led button on?

If the power led button is on, and it is the screen that goes off, this indicates that the picture board of your monitor is malfunctioning and will need to be replaced.

But if it is that everything goes off, it means the inverter is bad and will need to be replaced.

For the parts, yes, Being HP is even advantage, because virtually,most service centers do have the parts

Just walk to any hp service or any service center within your vicinity to get them.

Take care

Everything is too bright

I have a similar issue. Opened up the unit and found that a module on the power board had a small bit of the insulation melted, meaning that that module is overheating. It's just a matter of time before that module shorts out and the screen goes blank. The power board needs replaced.

Thanks man

Follow the PWR cable from the case to the mother board, and make sure it goes to PW_ON, and the PWR LED, goes to PWR_LED on the board (see page 33 of the manual). Additionally check that BOTH power cables from the PSU are plugged into the board (see page 18 and 28 of the manual, ref PW1 and PW2)
