    Steelshock 4 v2 controller
    by Péter Fodor
    I have got an Steeldigi Steelshock 4 v2 controller won't draw any amp from outlet.
    I have disassembled and removed the battery. I have tied to measure some points. The usb connector shows 5 volts. There are test points and shows 5 volts everywhere it should. The battery connector in diode mode shows 0.009v is it ok?

    There is an U4 chip place, but no chip, between the battery connector and the charging port.

    How should I progress to identify the problem?

    Can anyone help me with this?...

    Disable faulty soldered RAM on Acer A315-22
    by mat2k
    Hello, I've been googling for some pointers on this but couldn't find anything that applies to this board. I have an Acer A315-22 (board NB8607) with faulty RAM between 142 and 174mb. I just wanted to disable the onboard RAM altogether, but this one doesn't seem to have any memory down ID resistors or strap in order to disable it. I'm attaching the schematic I found, the boardview for it also seems to be available somewhere in this forum but I still don't have a use for it lol.
    How would I disable the RAM on this PC? Thanks for the help.

    How can I test non-polarized capacitor?
    by chth96
    I desoldered samwha NF capacitor(50v 5.6uf) from PCB circuit of 29inch CRT TV which have symptoms of no display after I heard sound of inrush of current to TV whenever I switch on this television.
    I measured ESR value of this non-polarized capacitor(samwha NF capacitor 50v 5.6uf) by means of MESR-100 ESR meter and It displayed 0.3 ohm

    And When I measured its capacitance with digital multimeter and LCR-T4 Mega328 meter, It displayed 10uf from DMM and 8uf from LCR-T4 meter.
    I found catalogue of samwha capacitor(samwha-catalogue_3.pdf file), which is attached to this thread,...

    Help with LCD pinouts
    by maleksa
    The LCD screen on my Roland Fantom XR rack synthesizer has gone blank. I managed to get the schematics for the connection to the LCD.

    The standard LCD has D0 to D7 pinouts (in addition to the normal VDD, VSS, CS, RES, RW, EN etc).

    Can someone help me to identify what V1 to VR is for? Also how does VR work?

    Any help is truly much appreciated....

    Pioneer PN50951-22U Backlight On, No Image
    by x_orange90_x
    I get backlights that stay on not there is no image. The tv does not automatically power on when plugged in either which I generally see happen when there is a fault. It responds as it should to the power button.

    I checked the test points on the TCON and I have proper voltages except for at 1P15V. I don't know if that is supposed to be 15V or 5V, but either way I only get 1.134V on that point. I have 12V, 8V, VCC, and a small amount on the CKV point.

    I tried heating up the SoC on the main board but that made no difference. Disconnecting either ribbon from the TCON also...
