Ok guys I have this tv stripped down to the led backlight. It appears someone had a Alcoholic drink spill all over this poor tv to where it went down the screen, onto the now very sticky driver boards. I've cleaned everything to the best of my ability. It seems what it is doing is just turning on and off over and over. When the screen flashes on for a second there is one small vertical line in the middle of the panel. Can you all tell me if this thing is trashed or if its worth fixing. When I plug in power to the psu and no mainboard attached nothing happens. When I plug in mainboard it starts power cycling forever. All the leds do flash when it does power cycle so the leds are all good. Now I am just wondering if it's the mainboard, psu, tcon or possibly the panel has permanent damage to the delicate ribbon connector from the liquid damage hence the vertical line? My money is on the mainboard personally but who knows can ya'll help me- thanks I can provide pictures of anything. The liquid appears to have run down the screen so all the main boards are all fine and undamaged except the driver boards look ok but they are fairly sticky.

Re: LG-49LB5550-UY Water Damage
If you don't get any image while it's flashing, it doesn't make sense to fix backlight.
But here is an example of me fixing water damage:

Re: LG-49LB5550-UY Water Damage
Ya unfortunately it looks like this screen sustained some physical damage to the screen as well. So I'm going to be parting this one out on e-bay or something I guess. Thanks for your help man. I cleaned all the ribbons good with ipa but still line so not worth fixing ya know.Comment

by edugimenoHi! My friend just brought this audio amplifier/speaker fro his music band saying they realized its got no sound. Led powers up but there no sound at all
I opened it and found 3 board. 2 of them are for input plugs and potentiometers, and the other larger board has the amplifiers for 2 large speakers that it drives
There's also a large toroid transformer that feeds a lower voltage to the first 2 boards and a larger voltaje (36x2 rectified close to 100v) to the power board. The power board has the plugs for both speakers
There is only one signal wire connecting the first boards...-

by Joel OhanaHi,
I have a Lenovo IdeaPad 3 15IAU7 that suffered water damage. It doesn't turn on (white power light flashes when on button pressed), and the amber light flashes when plugged in.
Symptoms:- Short detected – sparks appear when touching the charging port connection with board with a metal (even a multimeter probe).
- Visible damage – after cleaning corrosion, I found 4 possibly burnt memory chips near PC3165, labeled UD5, UD6, UD7, and UD8.
What are my next steps to diagnose and possibly repair it without replacing the entire board? Any guidance would be greatly... -
by abajorLike title says A2141 came in with Water Damage, customer desperately wants the data.
The actual water ingress doesn't appear too bad it sat for a day but was very dusty internally. I have no idea why L8504 was arced there is no apparent moisture there or around the LVDS cable; however, the LVDS to screen screw studs had popped off at some point and somebody tried securing it with kapton tape.
I had to create a micron wire pad jumper to reconnect the south side of the L8504 since the primary pad was blasted down to the vias.
That said after cleaning up the... -

by AndreasbestHello!
Today i received a Legion 5 pro with motherboard NM-D562 that suffered water damage, no power at all, no led, no fans, nothing.
I measure 20v on PQ5401 at pins 5, 6, 7 and 8 but 0v at 1, 2, 3 and 4.
Is this normal?
Thanks in advance!
