    right, on page-4 "BDMaster" gave one, later expired, re/uploaded, eventually got the courage to try

    #14 in this thread:
    [URL="https://www.bios-mods.com/forum/showthread.php?tid=13627&pid=65967#pid65967"]https://www.bios-mods.com/forum/showthre...7#pid65967[/URL] bios named: ACER ASPIRE ONE HAPPY_3.16_Acer21_UNLK.rar worked just fine!

    bios is now unlocked on the D255E, power and other options are available!

    Always knew such things are possible, first time actually doing!

    Thanks for the Merge and interest/offer to help, very encouraging despite it's relatively "old" age, still useful device!!

    not sure HOW to "dump" all original chip content out? will have to research, unless someone has a quick tip (how to dump bios out of PC..)

    Hopefully someone already has an unlocked bios for Acer D255E board: JE02_PT_E v3.16(DDR3), found this thread:

    but it's for different board, so not going to try unless can be confirmed it is safe/compatible..

    Re: 1-second to black 22" LCD need guidance

    Happy ending to this thread... ended up ordering a really cheap KIT from "China", it is totally different even though seller promised it is the same model to the letter.

    In any event, as you can see, nothing aside from the monitor ribbon/cable fit, different sizes plugs, etc. so speakers and controls are not working, but it's fine, there are external speakers anyways.. power is on front panel

    Thanks for the help, it ended up being the main board that was defective!!!

    Re: 1-second to black 22" LCD need guidance

    Here is an update, with new photos.

    Got a replacement Video inverter board in the mail, it looks good, and identical to original one, installed the new one, and same thing, 1-sec and it goes to BLACK (it does manage to print the LCD logo)...

    Took a separate interter device, and all 4 CCFL harnesses produced bright light on the display, so i was driving each one separately, and they all turned on and stayed on for long time.. which means the lights are OK, the inverter board is probably OK, which leaves...

    Re: 1-second to black 22" LCD need guidance

    Well, scanned the main board, could not find anything glaring, all diodes look clean, and low ESR.. then remembered some LED debug kit got while ago, in it was a small "driver board", connected it and:

    1) it did not power the CCFL on the monitor, i think that is expected, those require HV..

    2) it did deliver 12VDC on the output ports, put LED strips and it did power them up.. so , maybe the inverter board is bad after all...

    I might order something and see

    Thanks...

    Re: 1-second to black 22" LCD need guidance

    Noticed it changed behavior a bit with the two 10pF capacitors, maybe connection was not great, after POWER off, the GREEN light would not stay, it turned to RED light, i.e. completely OFF, power consumption dropped to 2-3W..

    so, put the original 5pF capacitors, and now after power off and GREEN light remains ON, with ~12W power draw, and the voltage values to inverter board are now (after screen is black, light is GREEN):

    vbrit 0VDC
    von/voff 4.8VDC
    vcc 12.3VDC

    these...

    just power, no video source.. I'm suspecting i would need to connect to some PC/laptop... ok, let me see if that changes anything, although it behaved in same way when it was on the PC, i.e. fade to black.. and the TIME seems to reduce, i.e. now it is less than 1 sec fade to black

    Re: 1-second to black 22" LCD need guidance

    OHH regarding the "vbrit/von/off/vcc" I think got it!! That maps to the 6 wires that drive the inverter board. OK, so, Tested again, here are some findings:

    1) Results are same when display is OFF (but energized, connected to power) and right AFTER the screen goes black, in both cases these are the numbers in relations to GND (black):

    vbrit 0VDC
    von/voff 90mV
    vcc 12.3VDC

    Maybe something is wrong with the "vbrit" ? or maybe von/voff is too low?? or both?...

    Re: 1-second to black 22" LCD need guidance

    Update:

    1) replaced both 5pF with couple of 10pF, as shown in photos, however, same black screen comes...

    2) After black screen, the voltage on the ribbon that feeds the inverter board shows 12V (red to black) and 5VDC (red to white) (maybe that is similar to what was asked "BL-ON, DIM"?.. so I'm thinking it is something with that inverter board..

    3) could not get the part# of U1, will need to go out to sun maybe with better quality light...

    4) I don't have any TV signal...

    Re: 1-second to black 22" LCD need guidance

    1) Yes, as shown, and explained in #4 they were replaced, with same effect of black after ~1sec.

    2) Based on reading such places: [url]http://www.facstaff.bucknell.edu/esantane/restoration/captester.html[/url], understood that a DMM cannot find such leaks of high voltage, and i do not want to touch the board when it is fully energized... not sure how to test. DMM shows OL when sent in Ohm mode, so i think that is OK.

    3) no clue how to do that...

    4) have not, will do that shortly.

    1-second to black 22" LCD need guidance

    Hi friends..

    The question up-front:

    Is it safe/OK to replace a ceramic capacitor marked "5J 3KV" (which I assume is a 5pF, with a 10J 3KV, which i assume is 10pF.. I know the general rule in Electrolytic capacitors that one can go higher on the Voltage, but not on the capacitance.. Wondering if that minor (double) change will result is some "hazard" when ceramic capacitor and high voltage is at play ?


    I've carefully reviewed this guide over past few days:

    Re: Repair Fence Energizer SS-1000E Fi-Shock

    Thanks, yeah, stopped it right away when it was in my possession, the first time it was in the farm, but then the second resistor burnt to the ground, so i guess it took all the "hear" so to speak. back side of board is clean/very good soldering for all parts..

    may report back in a month either way given the apparent "popularity" of this thread

    Re: Repair Fence Energizer SS-1000E Fi-Shock



    Dear eccerr0r,

    I was curious, so powered it up with open case, hopefully for the last time in a while the Ohm reading one side shows as 10M, flipping the leads shows it as OL (infinity) and when the TICK/neon light comes on, it goes to ZERO, so about every one second tick tick tick, it goes to zero, zero, other times it is OL/infinity..

    I think that is OK..

    Only thing now if it breaks it might be the resistors b/c some smoke did come out before diodes were replaced.. but...

    In this particular case, starting to think the WIRING is not 100% right, he was mumbling something about that, so now read up on how it should be done, may pay a visit to make sure enough grounding and no obvious (periodic??) shorts going on there



    Would not have been possible w/o the great support and spirit of folks on this board, keep up.. this is definitely not my day job, but I'll be sure to turn in future for help

    Lets hope this holds, and if not, I'll report just...

    [RE-RESOLVED]: Repair Fence Energizer SS-1000E Fi-Shock

    Hi there!!
    Maybe we can say Miracles do happen!!? Looking in pile of unopened parts, found these new diode strip, within 3 minutes the unit is back working, now ticking every second or so, and giving very good ZAPS, more sparky than before!

    Left it running for 20 min, and resistors were COLD...

    Lets see what the farm animals will think up this time around

    This was a joyful and fun learning experience!

    Thanks for the absolutely AMAZING encouragement ("dark...

    Re: Repair Fence Energizer SS-1000E Fi-Shock

    OK, took some time to test/measure, all tests were done without Load/COIL as follows:

    Test1: Pull 400v/16uF large capacitor OFF circuit (pull cable) and energize the board. that came OK, no heat even after 3 minutes.

    Test2: Connect 400v/16uF to board, energize the board within 5 seconds the resistors become super HOT to touch, Immediately cut power!!

    Test3: pull both diodes out of circuit, energize board, resistors do not get hot


    Measured components as follows:
