    Anyone here fix a tv and customer cracks panel when they get it home?
    by mecha1166
    About 2 times a year, a customer will do this. We fix the tv, put it on test play, and customer sees it working. They see me pull power and video wire. Sometimes I pick up tv, right in front of them, and carry it out to their vehicle while they are next to me. I set it in their tv gently, and tell them the tv is very fragile, be careful with it. I let them close the door/trunk. That day, or a few days later, they tell me there is a crack inside the tv. Normally I tell them transportation is their responsibility and normally that is the end of it. Has anyone had a customer that was not buying this...

    Philips 55PUS7303 LCD lines
    by rtstorm
    Hello, I have this 55" Philips TV that suddenly has these vertical lines on the LCD panel. I have checked the T-con board and I noticed some caps have 40Ohm I don't know if this is normal. These caps have 1.2V on them. I mark them on the photo with a silver pen. The T-con board has 1.2V, 12V, 25V, etc. Does anyone have any idea what could it be?
    i try to disconect one ribon cable and the problem is the same, one side is white other side have the lines (the same is in other way)

    T-con model: 55T32-C0L
    Main Board: 715G8579-M0F-B01-005T

    LCD Connector identify or source
    by reformatt
    Trying to identify where to source the LCD connectors on the motherboard side for a HP 14-cf2051la. This one came in with liquid damage to the connector and the flex cable. It appeared to clean up ok, however customer says that display blanks out intermittently. It's a 30 pin EDP flat ribbon cable on motherboard side. Believe it to be a HEDWIG-6050A3155301-MB-A01 motherboard.

    I've stolen the connector from another HP motherboard which matches up but it's not the best since it's been kicking around my donor pile for a while. This connector is different to most flip type ones I have...

    Dell Vostro 3420 BIOS Password Removal
    by sammus540
    I have a Vostro 3420 8H8K5R3​-8FC8 that freeze at any attempt to enter bios password or the recovery master password received from dell. I do not have a clean BIOS image to flash.
    And as luck would have it happened a couple of months ago right outside of the warranty period (Dec 2023) warranty expired in September. Any help or guidance is appreciated.

    Acer Aspire 5 a515-52g, EH5AW LA-G521P Rev.1a does not start.
    by andrhouseolly
    Hi goodday to all.
    I really ask for help.
    There are two motherboards (absolutely identical) Acer Aspire 5 a515-52g, EH5AW LA-G521P.
    Both boards have exactly the same fault symptoms. It turns on, the power indicator lights up for 5 seconds, turns off (the fan does not spin).
    Both boards are flashed with Bios Main and Bios EC from the “Bios Acer A515 LA-G521P FULL TEST” topic. XM25QH128AHIG replaced by W25Q128JVSIQ (also NOR-FLASH, XM was not detected by the programmer). On one of the boards, KB9022 was changed, followed by firmware. The fault persists on both boards....

    Hi community! Germany calling I am wondering if you guys can help me out. I have an issue with my Sony LED TV. I've been told this is a good place to ask. Thanks for anyone who will reply and offer advice. Appreciated!

For a few weeks I've got this problem where I turn on the TV and within a few seconds the TV starts getting darker until it shuts itself off and I get the 4 blinking error code. HOWEVER there is one exception: Whenever I switch to the i-Manual, a full screen on-screen instruction manual, the TV never turns off. I tested for hours!...

    Beginner Tutorial for using RCUnlocker to remove BIOS password?
    by CanukTuk
    Hello,
    Kinda new to this, so hoping you will all give me a bit of a pass.
    I came to this forum because need to remove the BIOS password on an HP EliteBook 850 G1.
    I understand that I need to dumpt the BIOS to a dump file, process the dump file with RCUnlocker, then write the modified BIN file back to tthe BIOS chip.
    Is there a beginner guide anywhere that describes the entire process for doing this?
    I am reallly in the dark regarding which tool or tools are required to extract the BIOS dump file, then write the modified BIN back to the BIOS chip. The guides I have...

    There is 2 sia ics and in 1 section where u see dots on the coils i have 2.2ohm there and there is no voltage on them at all.

    Also i read in other topić how psu works on these tvs and when u pług it in there is constant 40w draw from wall. When I unplug display from tcon it drops 10w when I unplug tcon it drops another 10w (unplug done w/o power ).

    I'm mostly sure its main board cpu cause no sygnał to turn on 24 volt for panel and its constant draw.

    For now I'm just curios about these w coils . Could not find any datasheet for ic thats the lines go...

    Lenovo Legion Y520-15IKBM - No power besides the main rail
    by Fronczek
    Hello people,
    I've got this laptop not working for repairs, and as you can see something was done to it as you can see in the coils PL58XX (which I for some reason cannot find in the schematics...) The first FET (PQ201) was not an original part and a questionable one at that and the second one (PQ202) was shorted. Both are N-channel. Ordered replacements for them and replaced them after arrival. Now I have encountered another problem: there is no power at the second FET. By following the thread linked I got to the injection part. Applied 0.8V at 1.5A, but couldn't feel anything getting hot,...
