Re: Lg 60pb4dt-ub
I had this issue in a different LG power supply, for a 37" LCD. The switching regulator ic was going bad. It regulated the 5V down to 3.4V. I just ended up replacing the power board completely but I'm sure it can be fixed.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Hello everyone,
I'm currently diagnosing a MacBook Pro A1707 motherboard that does not power on. I've gathered some data but am stuck and need expert advice.
Note that i'm a beginner in electronics and i'm trying to learn while trying to repair this macbook that my work gave me. I'm really curious and love understanding how thing works and i already learned so much.
Only one usb c port is taking 20v and have 12.5v on PPBUS_G3H. when trying other ports, 2 are not going to 20v and one is going to 20v but the CD3215 is getting really hot.

Hello all
got another TV here im puzzled by. why cant they all be easy fixes that just need a little love and some tape???
anyway i go to this guys house to look at an ONN 100012588
this is my first time looking at one of these brand of TV's.
TBH i have low expectations because i see ONN as the cheap walmart brand that suddenly popped up selling the cheapest version of all kinds of tech things. and someone sent me a ONN flash drive with some data on it with some recordings they wanted me to check out and it immediately broke and corrupted the data and i was unable to... -
Hi to all,
I was given this TV, an entry-level 4K 50" set. Some have criticized its lack of contrast and relatively poor colour rendering, but for my needs, it's very decent.
I reset everything to factory settings, but this line keeps on fading in and out when watching a streaming channel from the Tizen firmware. Interestingly, it only happens when TV is warm, after about 1h45 of it being turned on.
Watching a movie from an external source doesn't trigger the line as easily (needs 2 hours), and from a normal viewing distance, is hardly noticeable. It...01-10-2024, 01:26 AM -
Hi all, I tried searching the site for answers but I'm a bit over my head understanding some of what might apply and what doesn't, so please be patient with me. I used Freakaftr8's fix to remove the left driver board to restore picture to a black screen with sound Vizio E701i-A3. After doing so, I now have a large red vertical stripe down the center of the screen. The fix did require getting another t-con board from online, I ordered it before I knew about the mosfit fix for the old t-con board. I have tried cleaning the cable connections to the t-con board. I swapped the cables going from...08-19-2025, 06:11 PM -
Hi all.
I have a Kogan 65' LCD Panel with a thin blue vertical line (top to bottom) on left hand side of panel.
The line just happens to coincide with the end of COF and start of the next COF (attached).
The line is permanent no matter what I've tried. I've tried pressure testing the panel (top to bottom) and all over, I didn't notice any difference with the line, either temporary or semi-permanent.
Also tried unplugging all flex cables, cleaned with isopropyl then re-inserting to no avail - line remains.
Hoping to fix...
