Re: T - Con shcematic or voltage
Only known voltage is the 12V you can measure on the fuse. The rest are data lines -
Re: T - Con shcematic or voltage
Search on the board for a little solder dot whit the writing V_ON. That should be you LCD panel voltage if the T-CON power supply is working correctly. There are also other voltages to supply your ICs also usually written on the board near a solder dot (example V1.1 means at that point you should have 1.1V) .Comment

Re: T - Con shcematic or voltage
On the T-CON. Even whit the 2 connectors to the LCD disconnected you have power, as long you don't disconnect the cable to the main board.Comment

by cagriI have an Arcelik TV with BOE HV650QUB-F70 TCON board, but I think there's an issue with/around PMIC.
PMIC: iML8940
There is backlight and sound, but no picture. I watched a YouTube video and turned it off, half an hour later it was dead.
Input 12v, fuse ok
DVDD1V2 = 1.2v
DVDD1V8 = 1.8v
DVDD3V3 = 3.3v
VGL = -7v
**VGH = -0.3v
**VCOM0, AVDD, HAVDD = 0v
SWBK1 = 3.3v
SW1 = 12v
VGH to GND resistance is 500kohm as expected
Readings are same after I disconnected the two cables from TCON to panel... -
by x_orange90_xJust bought this for 10 bucks yesterday hoping to fix it. The guy said water dropped inside from a dehumidifier hose and it started showing black and white vertical bars then went blank. When I got it home and turned it on it came on fine and displayed correctly but I was noticing faint vertical bars in the image. After a little bit I turned it off and back on and it was a black screen again. I opened it up to check for water damage and corrosion but didn't find anything of the sort. I cleaned the ribbons anyway and reconnected them but still got a blank screen. If I disconnect the right side...

anyone have this ic pinout voltages?...06-25-2025, 07:19 AM -
Hi All,
Need help.
I have a samsung un60j620dafxza led tv. When I plug it in it has no display, no sounds, and no standby lights.
So I opened the tv and disconnected the power to the mainboard and the backlight powered up. This according to many people says that this is a mainboard
problem. I checked the voltage coming from the stb and I read 1.3 volts on pins 1,3,5 and 7 which are low volts instead of 13 volts which i think the lcd panel
might be drawing too much power from the power supply that it prevents the right voltage going to the mainboard.... -
by electron_jjHi Everyone, I am new to this forum. I have a Panasonic LED TV which doesnt turn on and is blinking 4 times repeatedly when I turn on the switch. The TV does not respond to the remote control so I had to turn on using the physical switch on the side of the TV. When I turn on the switch the 4 x blinking starts and repeat itself until I turn off the TV. There is a black screen. I turned off the light in the room to check the panel and I think there is no backlight as far as I can tell.
I have been inspecting and testing the capacitors and diodes in the power supply board to try to... - Loading...
