Think Out Of The Box!

Well, yesterday's post was about modification of electronic circuit, and today I have another tips about modification. If you repair monitor i'm sure you have come across a dual diode part number which is the DMV32B or DMV56. In the package there is two diodes-one is the damper diode and the other is modulation diode. Most problems with this dual diode package is the modulation diode always developed a short circuit. If you can't find this part then you can modify it. Solder out the modulation diode pin and connect externally a ultra fast recovery diode-UF5408. How do i know if UF5408 diode can be use to substitute the modulation diode. Just go to the Dmv32b manufacturer which is the SG Thompson and download the diode data. From there you will know which type of diode is suitable for replacement. Even if the damper diode shorted, you may also look at the spec and find an equivalent number for it. But so far, I've never come across a damper diode shorted in the dual diode package. Hope from this tips you will be able to modify electronic circuits at the field you are in.
