Re: LG 55EC930v is not turning on, it's dead
This shows the New T-con. The t-con has got also a metal Chip and not this plastic chip.
Old t-con didn't Show this. With old t-con TV cames on sometimes. Monday he Was running for 3 minutes without problem. But had to try 20 Times before. And there were sometimes orange and other colored horizontal Lines. I uploaded a Video a few days ago with this issue.
If i'm Home then i will add more pictures.Attached FilesComment

Re: LG 55EC930v is not turning on, it's dead
can you please tell me where you read or learned to remove one ribbon cable or LVDS on OLED ?
do you believe this replacment T-CON driver board are new ??
if you do as you like later you will lost the panel too. just advice.
now about the green. this happened when the T-CON driver boards defect. or its firmware didn't match the micom version at the main boards,
i would suggest first send In-STOP with replacement t-con.. hopefully the temp data can write t-con again... or as i know you had replaced the main boards before... try download the last firmware and update the LG
you can do this first to yours original t-con as it show better result than this scrapComment

Re: LG 55EC930v is not turning on, it's dead
Okay, i will put original T-con back and i won't touching anymore the ribbon cables. Yes i did it once with in-stop, but i had to remove LVDS cable because he wouldn't turn on with this replacement t-con. Did in-stop and after that i reconnected the cable and t-con, it shows the same.
I don't know if it's new.
Is there a PC Tool to update the TV without screen?Comment

Re: LG 55EC930v is not turning on, it's dead
for both points i bold marked.. IN_STOP command its not only for MB.. its to T-CON too.. because the firmware of the TV had one part saved on the T-CON driver boards.. so any sending command or update with out LVDS are ZERO EFFECT.
but you can disconect the 24V line between the PCB and T-CON.. the set will remain on and lvds should be in place... the command IN_STOP will reach the T-CONLast edited by Diah; 01-14-2022, 11:33 AM.Comment

Re: LG 55EC930v is not turning on, it's dead
plug the lvds straight 180° to avoid it move again to side... then turn on who knows it could run more than 3 minutes as last time.... if it run and it show u first install screen... do in stop again.Comment

Re: LG 55EC930v is not turning on, it's dead
Powered on, tv was on first install screen, but before screen appears there always appears a bit of green color on right side, also a odd line moving down. after it reached the end, i saw the loading screen but also a lot of orange lines flickering. After that it turns off. I did in_stop without 24v power cable because he turns off. all screen cables are in place. Can look tomorrow again for the TV. I have a bad feeling..Attached FilesComment

Re: LG 55EC930v is not turning on, it's dead
For me it looks normally, no cracks, no missing pin. got also these cables additional with the another "trash" T-Con. LVDS should also be OK, but the seller of it bended it really hard in the middle when it arrived.Comment

Hi guys, I have an A1466 (820-00165-A) board which came in dead, had corrosion on R7181 near ISL6259 chip. I removed corrosion and replace R7181 and the macbook powered on.
After sometime I didn't get any light on the charger but fan was spinning and I was getting battery charge logo on the screen, so I replaced the ISL6259 chip and it came on! everything was working fine.
(NOTE: Customer had previously got the battery replaced from another shop and it was third party bad quality)
I had used my test SSD and my known good original battery.

Hi all,
As the title suggests, how can I be sure that my EC chip is really dead?
I've recently gotten into this hobby of laptop repairs, and have successfully brought back to life a couple with some easy fixes, mostly shorted caps.
Now I'm working on HP Probook 455 G8, that had some "devil" run around on 3V line, burning a bunch of stuff. Luckily I have a dead 455G7 (for spare parts) so I managed to fix it (swapped burned parts) to a point that it will charge (both on barrel jack and usb-c), but it doesn't want to turn on. There is a 3V3 on a keyboard... -
hello guys,
i need help to repair a edm-033 ps2
history : as always hdmi port and usb ports destroyed after unplugged
after change them, ps5 dead too : 1 beep, no blue light. after inspection 1.8v power was shorted, and because of dead panasonic chip. after remove it : no short anymore
so i changed it
now i have got 5v stby,, 3.3v stby, 3.3v power, 1.8v power and no short on them
but the ps5 is dead again : 1 beep, near 10 seconds with power lines and then off, no blue light ...
i don't see any projection of liquid metal on pcb.

I have a Haier 50" LE50d3505b television that is "dead." No image, no standby lights, no sound, no nothing. The power supply board is HKL-500201A, and physical inspection looks good. I have tested the fuse (works) and the bridge rectifier (works). Also, the capacitors are not "puffy." However, a couple diodes seem to have faulty test results. I have tested diodes 10/11 using the "diode setting" on my multi-meter. I got .000 readings for both. For diodes 13/14, I got .177 for both readings. Do you think just these diodes are the issue? If so....would these be... -
Hello everyone hope all doing well!
I have this PSU (GPS450-AA delta oem) around for like 4-5 years and I had it recapped early 2020 or 2021 with mostly UCC KY and Nichicon PW's. The bulk was and still is fine, the original Ltec's were bloated and empty. The previous issue was some major coil whine noise and at times random shutdowns when going idle. Today it started tripping the mains breaker and I think I have dead APFC mosfets (20N60C3). Right now upon checking I have the Q1 and Q3 FETs dead so far and I guess those are responsible for the PFC circuit. The only thing I care is If there...
