Hi Technicians! Today we have a very useful post for you. Here in this post you will learn LCD/LED TV Display Panel Connection & Voltages Understanding. So this is a very demanding topic, many beginner and new technicians are being stuck on LCD/LED TV Display Panel Repairing. So this post will guide you LCD/LED TV Screen panel all connections and their voltages to check. You can check every voltage point on your Display panel according to this post. It is important to know where to check every voltage of each connection as they mention in the schematic diagram and service manual. At least you should know the basic working.
We have collected all this information from deferent sources. So we are not responsible for any damage by using this information.
LCD/LED TV Display Panel Connection & Voltages Understanding
| Connection Name | Working Voltages |
|---|---|
| VGL | Driver Negative Power Supply 1 Around -10.5v |
| VCL | Driver Negative Power Supply 2 Around -10v to -12v |
| VSS | Digital Ground GND |
| VDD | The Logic Supply Input for the Scan Driver |
| VGH | Supply LCM driver output Around 12v+ to 19.5v+ |
| CPV1 | Vertical Clock-Pulse Input. CPV1 controls the timing of the CKV1 and CKVB1 outputs, which change state (by first sharing charge) on its falling edge. Pulse |
| CPV2 | |
| V.COM | Out Vertical Clock-Pulse Input. CPV2 controls the timing of the CKV2 and CKVB2 outputs, which change state (by first sharing charge) on its falling edge. |
| POL | POL in Supply input common signal |
| VDC | In Supply +5.0v min |
| VON | Gate-On Supply. VON is the positive supply voltage for the CKV_, CKVB_, and STVP high-voltage driver outputs. Around 20v+ V-OFF Gate-Off Supply. VOFF is the negative supply voltage for the CKV_, CKVB_, and STVP high-voltage driver outputs. Around 8V |
| CPV1 | Vertical Clock-Pulse Input |
