Re: LG/Optica 7074c / 42" SmartTV
Thanks for the help everyone.
I should have got some solder paste really, one thing to note if you heat the strip from underneath it is easier to work and causes less stress on the LEDs and i would not try
this without a rework heat gun.Last edited by badcaphunter; 09-01-2016, 06:33 AM.Comment

Hi everyone, over the past few months i have taken a deep dive into motherboard diagnostics and I love the challenge. Currently im trying to learn all about the signals that travel around the motherboard, such as frequencies, enable signals High and Low logic states etc. And i have been learning to read and using the Schematics for this board that i requested here on Badcaps forum, from a few months ago, this is such a great place for these.
I’ve been working on a GA-970A-DS3 (rev. 1.0) that does not post. This motherboard has been my main learning board. I would like share...11-23-2023, 11:02 PM -
This is A2289, board 820-01987-A. It came in with the screen not working. We could not see any image on the screen, so we ruled out a backlight issue and instead replaced the panel. The display now comes up, but no backlight.
I didn't see any signs of liquid damage, but there was some odd looking spots around U8400. F8400 has voltage on either side of it, and I have 5v present on R8444 and R8445. I did not have 3.2v at R8442 so I figured U8400 was bad, and I replaced it. After replacement, a brief probe to R8442 showed 3.2v so I assumed I had fixed the device. After reassembly however,... -
I had this tv set, stuck at the 'SMARTTV' screen with coloured logo. Impossible to find the original Smart Tech firmware, so i searched in kazmielec.tech some firmware compatible with the tv-set hardware (CV338H-T42 card and Y400HJ6.PE1 screen). The firmware i tried was wrong and it bricked the TV, just showing a black screen and not entering stand by anymore. I supposed it needed special hardware to reflash the NAND, but i was wrong, it just needed a working compatible firmware. Still in the kazmielek page i tried ' CV338H-T42_1920x1080_Telefunken TF-LED43S81T2' and it finally worked. I wrote... -
A customer called me up and said that half the screen was like a shadow - presumably the backlight has partially gone. I've never done a repair like this on a monitor, only circuit board based repair on Macbooks etc - is it something that's doable or generally not? -
Hearty greetings to everyone, trust you all are doing excellently well.
Please, I have the above problem, the laptop turned on after the switch was activated but it will turns off in less than 2 seconds.
The power stables in very rare case. Once it was stabled, everything works fine.
Once the power switched is pressed, 5V and 3V were present.
The things i have done:
1. I have check for shorts on the board, but nothing. The board is short free
2. Not a power switch problem, it behaves the same without the switch ...06-10-2024, 05:05 AM
