Does anybody have the schematics of this Reflow Soldering. I cannot get more than 70°C air flow from the pipe. Thyristors TIC126E are good, FRP1610 semiconductors as well. Voltage regulator LM340T12, Zener Z1 and ER1 diode bridge too. All other semiconductors resistors are good. Anyone...
I'm searching the schematics of the pcb from an LKB220 welder unit. The name of this PCB is LKC12.
This PCB is also used in Migmag 160 and 240.
The service manual of the welder unit gives only parts of the schematics. Mine welder will not start (contactor vibrating!) I suspect a issue in...
I have a secondhand TFT Color Screen video with a 8-pins mini subconnector without any documentation and remote.
I can find the characteristics of it but nothing else. It is also known as CUB-HR-070 or AV-070 and can be used with a DVD AV9750.
The PCB inside is marked Smart View SVL-R1.4...
I'm searching for the calibration procedure for this M.B.L.E (or SRE - Scuola Radio Elettrascope) (about 1970's). I think this procedure was a part of the kit documentation.
I've the schematics.
With kind regards,
Re: Welding unit DALEX GI 130 with PCB WIG 18 RK
The one I have got was out of service : no voltage at the output. After check I found that a resistor (10 ohm 17 W) on the PCB was out. I replace it and now the voltage is 48 V.
I still need the user and service manual.
With kind regards...
My old micronta 22-193 is faulty. The LCD gives BATT while the batteries are good. The readings on DC are faulty : 0,6 V instead of 1,5 V.
The main IC is a SXC 1901F of which I do not have got the datasheet.
Does anybody have this datasheet or have the same trouble with this autorange...
The power connector of this laptop from Packard Bell is shorted. Due to a faulty power supply the user has replaced it by another one but he has permuted the Pos and the Neg. After a google search i have found nothing about the schematics of the power pcb. Does anybody have the schematics of...
Can you specify which old electronic equipment it is.
For example VCR type DAWOO has this strange reactions. In fact it is due to a rotating switch which gets soiled. This switch has to be cleaned with alcohol en then the issue disappears. Some inexpensive equipment has no logical...
