Hi. i need you advise. I have panasonic 49".. Tcon board use 3 pcs cable. 1 pcs cable from mainboard, 2 pcs cable from LCD L+R. (Situation 1) If i connect 2 cable from LCD, and test t-con voltage, only got 12v voltage at fuse. Others voltage at vgh vdd & etc is missing. (Situation 2) If i remove 2 cable from LCD and test, All t-con voltage working good.. Help me please.
Please my VGH is 3.98v and VCOM is 1.48 and VGL is 0.52 , the monitor is displaying only white . what could be the problem? is it the power supply or the Tcon
Nice explanation! May you help me? My TV is black without anything, just backlight. My TCON is v500hj1-ce1. I measured VGH and it is 12,5V. The others voltages (VGL, etc) are good. Is it the cause? Is it a problem of DCDC IC? Thank you!
@@madiskartech : The backlight lights normally when I turn on the TV, but there is no image. So I imagine the problem is with TCON really. Thank you so much for your kind reply! Have a ncie day!
Hello and thanks for your videos! I have an LG 34UM59 monitor, which is showing the images and also the settings menus perfectly but they are all in white colour shades, like all “washed out”. Can it be one of those components on the board? Should I test the voltage? Can you help me? Thanks a lot!!
@@madiskartech the VCOM points shows a voltage of around 1,5v.. is it too low? What component of the board is responsible for this? One of these three maybe? ibb.co/R7HTqJ3 ibb.co/BP0Fzpg ibb.co/QFMf24T
Hi, can I have some help please? I have LG with the backlight working fine and so is the sound and hdmi input but there is no display. When I checked the voltage on the VDD it showed 8V. What could be the issue? Thanks
.. tried removed cable, tcon to source board then measure the voltage input of tcon and vgh, vcom, vdd & vgl .. if abnormal ang normal input voltage of tcon .. replace new1 tcon.
Fantastic explanation Thank you so much !
I have 16.37volt on VDD T-CON instead of 3.3 volt is that DC TO DC IC problem?
¡Gracias!
Thank you! 😊 🙏 💓
cv500u1-t01-cb-1 hol vannak a tesztpontok, mekkora feszültségnek kell lennie? Tudnál segíteni?
I check the input voltage is only 0.897v and no backlight. So i need to replace the t-con, right?
Tq for the information bro..👍👍
hola dabes dónde está el pin mirror o donde hay que buscar

Help me please.
My tv is showing horizontal lines does that mean there is a problem with the tcon?
My VDD and VGL shows open when measuring voltage ,, which ic can i change
I have on V14 TM240 6870C-0482B - VDD=16,12 V. It's wrong ? Problem it's half matrix is not work
Please my VGH is 3.98v and VCOM is 1.48 and VGL is 0.52 , the monitor is displaying only white . what could be the problem? is it the power supply or the Tcon
Check the input Voltage of tcon

Hi sir, thanks for comment ... With sounds or no?
@@madiskartech : With sound and backlight. No image. Thanks!
Check Backlight is ok .. if ok all led backlight ok, check inverter driver board, if ok.. change tcon board.. .

If ok led backlight & inverter driver board .. suspected mising Voltage at tcon board or source board .. .

Hi sir, check tcon Voltage and data source board into panel.
@@madiskartech thanks for the reply! What point should I try exactly? The ones in the video?
@@madiskartech and.. what do you mean with “check data source board into panel”?
Yes sir

One of these three maybe?

So nice video & useful
I dont have input voltage in the Tcom, where i have to check?
The input Cable to T-CON

Hi sir, vcc to ground 18 ohm,,,,where i must cek?
12 v ok
Other 0 v
check mo sir fuse if ok
Very nice sirsir
much thanks !
I love this
amazing video
Good
0:20 Vdd is typically approx 15 Volts..
I have the same problem, did you get solve to it?
LTY400HL04-B
Check other mother board
3.3 is vcc not vdd
