    HP P1120 brightness too high

    Is there an adjustment for overall brightness/contrast inside the back of the p1120?
    I've found loads of adjusters for focus/warp etc, but none relating to colour or brightness.
    My display doesn't show black as black, it's doesn't go dark enough using the front panel controls.
    I also have an hp p1100, the most noticable difference between them is the colour black.
    I have a problem similar to jdimpas in this thread :

    I can live with the thin lines across the screen, I just want the brightness sorted.
    If there is an adjuster pot could you attach a jpg showing it's location please instead of telling me the technical name.

    Cheers

    Grundig CUC 2401 CRT TV - Brightness is too high
    by Flybacks
    Hello, I'm trying to fix a Grundig CUC 2401 with picture brightness too high.
    The problem seems to be in the brightness voltage supplied by pin 16 of TDA8442 that should be in the 1-3V range instead it is about 3.2V.
    If I manually lower the brightness the voltage goes in the right range of about 2V and doesn't increase but I don't understand why at start up it is set wrong ?
    I've already changed TDA8442, the video output IC TDA3505 and the microcontroller IC811 but it didn't fix.
    The collector of RGB transistors on crt board are about 170V for red and blue but 150V...

    Is there any high current pouch battery that are size 60mmX80mm maximum thickness 21mm for a battery operated tab welder
    by sam_sam_sam
    I have a battery operated tab welder and the battery does not have enough current for the battery tab welder because after about 30 welded it does not have the same current output it voltage has gone down by at least 0.500 volts or maybe a more than that

    I can fit 21700 battery cells in the enclosure it is very tight fit for four of them that are 35 amp high current capacity 35X4=140 high current output this should work a lot better than what is installed right now

    I tested the battery cells there are installed right now and they are testing good with no issues that I...

    Extreme High Current & Low Voltage Short Killer ??
    by DynaxSC
    Hi Folks

    I'm looking for a extreme high current short killer solution for a reasonable cost.

    I have an LGA1700 motherboard (ASUS PRIME Z790-P WiFi) where I exchanged the LGA socket already 3 times, and every time after the socket exchange I get a short of power supply lines VCORE (V variable) and VCCIN_AUX (1.8V).
    After taking off the socket, the shorts dissappear again.
    The soldermask on the socket is already partially demaged from the heat, so I have reconstructed the soldermask by manually painting the missing soldermask parts with a very small top of a...

    HP Pavilion 15-1812nd scrren brightness issues
    by dr.thodt
    I have a notebook, HP Pavilion 15-1812ND with brichtness issues.
    When in windows, I use the the brightness keys on the keyboard, brightness goes up aprox (75%) then the screen begins to flicker and gets darker again.
    When I lower the brightness again it's getting brighter first and then it dims and the flickerings gets less.

    I already chaned the screen and LVDS Cable.

    Does anyone ever seen this problem and maybe have an idea how to fix this.
    Any help would be apprecited.

    Thank you

    Is there any reason why high voltage high resistance resistor use weird marking and value on it? Standard nomenclature, EIA value not used?...
