Used in V500HJ1-PE6 C1, V500HK1-XL, and V500HK1-XRS5 Panels
NT39565H-C5253A side COF data This COF data is used with the scalar strip of three different types of panels: V500HJ1-PE6 C1, V500HK1-XL, and V500HK1-XRS5. This article contains a complete picture of it in PDF format. You will find a link to it inside the article. You can download it. This data is being published by the Sony LED TV Repair Center for fellow technicians to make their work easier.
| Pin # | Signal / Function | Description | Test Point / Note |
|---|---|---|---|
| 1 | VGH | This voltage is used to keep the TFT gate drive in a high state, in simple terms, these voltages turn on the gate drive. | Expected: +27V |
| 2 | VGL | These voltages are used to keep the TFT in a low state, meaning these negative voltages turn off the TFT. | Expected: -7.8V |
| 3 | VDD | This power supply operates the logic circuit for the source COF and also for the internal panel. | Typical: +3.3V |
| 4 | GND | This is ground. It works everywhere in the panel’s internal circuit, including the scalar strip. | ~0V |
| 5 | STV | The function of the STV is that it generates clock pulses, which is where the scanning process begins. | 0.04V |
| 6 | CKV | CKV is a clock signal that causes the gate drive to shift the line, which is why double image faults are seen in some panels. | +1.71V |
| 7 | OE2 | OE2 This signal enables and controls the output of display data. | +1.36V |
| 8 | OE1 | OE1 This controls the secondary signal output. | +1.36V |
| U | UD | UD Its function is to control up-down scanning and it also identifies the direction of vertical scanning. | 3.3V |
| L | LR | Its function is to control the left-right horizontal shaft. | Â +3.3V |
| R | STVR | The STVR starts the backup line and this is the secondary start pulse signal. | 0.06V |
| V | V-COM | Common voltage flicker and screen black level setting | +7.3V |
| NC | NC |
Conclusion
This is the side Cof data of the V500HJ1-PE6 C1, V500HK1-XL, and V500HK1-XRS5 panels. We are sharing this data to help Purely technicians so that their work is easier and they can do their job better. In this, you will get the test points of the three scaler strips, and you will also get the test points of the Cof. The link to the full detailed images in 4K is given below; you can download it.
