I took an ebay gamble on an LG xboom pn5 speaker which was listed as having battery issues (turning on then off).

I got it earlier today and concluded it's in a demo mode because of the following:[LIST][*]When it's plugged in, it'll turn on and the power button will not turn it off[*]Battery is healthy, reading 4.2v and not swollen, charges according to the xboom app[*]the play/pause and volume buttons don't work[*]You can pair to it and play music fine, as long as it's connected to power[*]The bluetooth connection is disconnected after 5 seconds of audio pausing[*]The DTS setting...

Some additional information: I had used LVDS cables from ALIexpress with the LG connectors on the panel side. As this panel has 2 connectors I needed two cables, one with 51 pins, the other with 41 pins. Unfortunately for one of them I could not find cables with 5 data pairs, so I have 4 data pairs for two LVDS channels on one connector and 5 data pairs for also two LVDS channels on the other connector. This leads to first LVDS Receiver Signal E +/- and second LVDS Receiver Signal E +/- are not connected, while for third and fourth LVDS Receiver Signal E +/- are connected.

Hi all,

I've got a LG 50PK590 plasma TV which upon plugging in will click three times and the red LED in the corner will come on and stay on, the TV however doesn't come on (no humming, sound, video, etc.) and using the touch controls or the remote does nothing. On exceptionally odd occasions, the TV will come on and work normally when plugged in and will last about 5 minutes before going back to off and unresponsive.

I've got the back off of it and none of the caps stand out as visibly buggered, I've also tested the three resistors in the corner of the power board which...

I've owned this C1 from new since late 2021, and it has now suddenly started with the following symptom:
If power has been connected for a while, the red standby lamp turns off, and the tv wont turn on (no reaction from remote or button on tv).
If power has been disconnected for 5 minutes, the tv turns on fine, until turned off and left for a couple minutes, as the standby light will then turn off again.

I've seached and found that this is most likely a failing PSU, and I've seen repair services on eBay fixing these symptoms, so I am hoping that someone here has fixed...

Hello everyone! I've found this television, and I began troubleshooting it.

First, the television kept rapidly power cycling. I've warmed up the capacitors with a hairdryer, and after 3 dimmed red blinks, the backlight turned on, then turned dim, and no picture was present on the screen.

I believed that this was caused by a bad power supply producing insufficent power (I've measured 3.5v on the 5.2v rail), so I've blindly recapped the board.

After the recapping, all the voltages stableized, however, the issue in the title still remains.

I could...

Hi,
I've been living in the same apartment for about 5 years now, and moved into it with my old Samsung plasma TV (PS51F5500).
Ever since we've moved in, we would sometimes see strange power-cycling behavior. For example:[LIST][*]TV would randomly turn off then back on.[*]TV would turn off and the LED light would blink for a while (over a minute sometimes) until eventually it went back to a regular off state and could be turned on[*]Sometimes it would require disconnecting the mains cord from the TV, waiting several minutes, then putting it back in and turning the TV back on. This...

Got it for free on marketplace because it stopped working after a storm.

When I began troubleshooting the power supply, I fried 2 fuses and a mosfet by shorting 2 pins on accident, but I've replaced those components.

The tv had a soundbar connected, which was also killed by the storm. On the tv side I found a transistor shorted on the hdmi 2 (arc) and a lot of capacitors shorted on the main board.

Disconnecting and reconnecting the psu to main board cable, while still being connected to 120 V AC, would wake things up, such as a red light from the optical...

The 55" LG has been in the basement for a few months without being used. Turned it on yesterday, set came on as it should and showed a complete screen for about 5 seconds (was on a broadcast channel but no antenna was connected), then the screen went mostly dark with about 1/3 of the screen on the right lighting up with brighter lines in that lit part (sorry, no pictures of that). Power LED was cycling too, preventing the TV from fully powering up.
Pulled the back off, all boards looked OK. Pulled the LED connector, turned the set on to see if it would power up but I don't belive it...

I'm looking for a dump for the LG PF1000U projector (chassis FM51E), (NAND Hynix H27U1G8F2CTR SPI_FLASH: MX25L8035EM2I, EPROM 24C256C).

There is no epk file available anywhere

This device attempts to turn on and responds to both buttons and the remote control:

It exits standby, runs the fans for 5 seconds, then spins them at 100% for another 5 seconds judging by the sound, and then goes back into standby.

The problem seems to be a corrupted NAND as it appears to me:

Hello guys,

I recently picked up an LG C1 in 65 inch size. Previous owner told me that the TV won‘t start, so I did believe due to PSU issue, but not this time. I could narrow it down to the T-Con or Panel.

PSU and Mainboard work both like intended, all Voltages available, Optical on when T-Con lower Ribbon is disconnected and I even managed to get some picture with P-Only, IN-STOP cycle but only for 2 sec. before shutdown.

For the stand alone test the panel starts with some flashing horizontal white lines and then continues to build up some color on the...

This is a 2012 LG TV so aware full functionality of the smart functions/apps will be limited however currently unable to get the LG Smart Store.

Youtube, Netflix and LG Smart store icons briefly appear in the apps list but then automatically disappear after doing 'Initialisation of Premium' via the standard menu, I'm guessing this is due to the Country/Area group its set to is wrong for the UK.

Unable to change the country group, Area option can be changed which alters the country group but none make any difference. So believe its the country group that needs changing....

Hi guys,
I have a problem with this monitor and i need your help.
Is this a bad power supply, bad mainboard or bad panel?
The panel is a LG LM220WE1.
If the monitor is powered off for 2 or 3 days, upon connecting, image appears without any issue for a few seconds only.

My measurements so far:
VGL: -5.362V
VGH: 33.12V
VGH_L: 33.12
VDD: 12.70V
VCOMC: 5.535
GVDD_E: 33V oscillating with -5.3V
GVDD_O: Same as GVDD_E
VIN: 5.112V
SCL/SDA: 3.3V

Thanks in advance...
