There are actually several kinds of tools that can be used for check whether flybak damaged. But we have a simple way we have always done for ascertain whether flybak damaged or is still good, before replacing the horizontal transistor. All it takes is a light bulb with an added Exciter 100Watt cable connection along approximately 25cm. The trick determine if flyback damaged or is still good is as follows : Break up the relationship between the collector of transistor horizontal flyback-out. By (a) Open collector aspirated by means of the printed board solder, or (b) Remove the jumper cables if any, or (b) Cutting prited path. Ac volt-meter pairs of horizontal transistor base with a ground out. Turn on the plane a little while - there must be an ac voltage of about 1v. This is done is for ensure that the horizontal oscillator and driver are working horizontally. Replace light bulb between the collector of transistor flyback horizontal (light diseri the collector). Turn on the plane...

Judge the Error through the Indicator at the Front Panel When error occurred for the DVP PLC, please check : POWER LED There is a “POWER” LED at the front of the MPU. When the MPU is powered On, the green LED light will be on. If the indicator is not on when the MPU is powered up and with the input power being normal, it is an indication that the PLC is out of order. Please have this machine replaced or have it repaired at a dealer near you. RUN LED Identify the status of the PLC. When the PLC is in operation, this light will be on, and users could thus useHPP or the ladder diagram to edit program and give commands to make the PLC “RUN” or “STOP”. ERROR LED 1. If illegitimate program is input to the MPU, or that the commands and devices of the program exceed the allowable range, the indicator will thus be blinking. In this case, the user should inquire about the errorcode from the special data register D1004 in the MPU and look it up in the Error Code Table. After the error is found ...
