Re: UE55F7000ST clicking on/off
the thing is tho, I don't think he mentioned repeated clicking in his issue.

Re: UE55F7000ST clicking on/off
pretty sure this isn't normal, with cable from powerboard to mainboard unhooked, when you plug power cable into powerboard and plug it into outlet, the backlights should come on and stay on, without repeated clicking, so the problem is at the powerboard or backlights.Comment

Re: UE55F7000ST clicking on/off
Well I'm still flummoxed
PS Board still stays on if left overnight with or without Backlights attached but main board detached. Second power on it clicks on and off with backlights.
with main board attached it clicks at a slower rate and Backlight won't come on and no sound at all now. The Tcon board shows only two blue leds light up they flash on and off in sync with the relay clicking about every eight seconds the red standby led flashes twice for five times between the clicking.
I Have read in a few samsung service manuals that all three blue leds must be on
I assume the three voltages are derived from the 12v at the fuse. I have just ordered
a used Tcon to see if it's the Tcon causing all the issues.Comment

Re: UE55F7000ST clicking on/off
Don’t think it’s Icon now as when 12v applied to it standalone all 3 blue Leds light up
i’m thinking maybe PS now as I don’t think it should be clicking in any combination
of connectors in or out.
Can anyone confirm that? the PS is BN44-00633B
I found a schematic for PS BN44-00633A but i have no idea of the differences.Last edited by shandy; 06-21-2022, 05:31 PM.Comment

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... -
Hello, I bought this Mac from a friend, he said that it simply stop working. The MacBook looks very clean but does not power on, stuck on 5v 0.42A, and sometimes display 5V and 0A (then 0.071A and again 0A).
I opened it looking for some problem, it was not touched before for sure and the board is very clena, no spot of corrosion at all from what I can see. Voltage on multimeter of the board off the case it's the same, 5V 0.42A. But then I noticed this "clicking sound" come from the board ( I attached here the audio file).
Looking on google I found this:... -
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.

Problem
This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached.... -
Hi There,
This TV was auto switching off after few seconds with some vertical lines on the screen, so got a new TCON board and replaced it.
After replacing the TCON board it was working fine and i set it up with everything, used for few hours, then had the bright idea to update the software on it. During the update process, TV switched off and now no audio or video. No relay switch sound.
More Details
TV Model - LG OLED77G1PUA
Got the same exact TCON board from TVPartsToday and replaced it. But didnt transfer the EPPROM data (didnt...
