Re: Hitatchi 32LD30U A
Does this TV have a separate logic board? Pictures of the chassis layout would help. Typically it would run from main to t-con.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Hitatchi 32LD30U A
Ugh, it's a VESTEL. Yay.
From main board, with video inputs on it, to t-con board, the cable should be checked. Reseat it too.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Hitatchi 32LD30U A
I Have had it off,Cable looks fine ( reseated it ) and moved it about while the TV was on to see if i can get it to stop or change how it behaves ...
here is a small video of the TV might give you a clue ....

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic... -
I hope this is the right forum to post in despite not technically being a repair, but still a question of swapping boards.
I thought I'd explore the possibility to upgrade an existing working Samsung ue55nu7096u with the logic board (and power board if needed) of a newer model (ue55ru7105k) of the same size and appearance (and resolution). The reason being I'd like the extra inputs of that board including component in, an extra HDMI port and bluetooth. Its panel is broken so I have no use for the board otherwise.
The models launched in 2018 and 2019 respectively.... -
Hi all, I just want to share the repair of my 60PK550-UA TV set.
The TV set was powering on, just no image. After verification, nothing wrong on the YSus or ZSus boards. Nothing wrong on the main board either.
But I noticed that the LED was not flashing on the Logic Control Board. This is an EBR63450301. The LED is supposed to flash even with all the flat cables disconnected, with only the power cable attached.
All the voltages measured at the electrolytic capacitors on the board were good. From top left to bottom right:
C57: 3.30V

Hi everyone! I'm trying to fix my black screen / failed U8900 GPU v-core on my Mid-2012 Macbook Pro 15" Retinaby doing a rework/reflow of the chip (once I determine that's the real issue; but it likely is).
I've been disabling the GPU in NVRAM for a few years... but it's just time for a better solution.
I'm new to soldering but the only feasible way to fix this issue is to do something myself.
MY QUESTION:
I've been seeing some people (on this forum mostly) run into issues with the logic board needing a serial number or it being deactivated (?)...
