COF (Chip-On-Film) Technology is widely used as a package for LCD Driver ICs Using a Reel-to-Reel system. COF tape can be mounted using solder. In case of panel failure of LCD/LED TV the following symptoms may usually occur:

The cause of the above symptoms is the failure of one of the contacts between the Glass side of the panel glass or between the PCB/Tcon Board Connections. If we diagnose the missing data on gate cof the repair solution is possible by bypassing the missing data/voltage from T-Con Board to Cof IC Points but this process requires good skills.

scratch gently the paint on the center of each pad and contact them with the tester of the multi-meter. When you are able to scratch the points then you can connect thin wire but for this, you need to identify the points first. So, here are some Cof Data Points for the technician’s support for free download.

1. #Confirm whether the COF on side X is hot compared with the normal temperature, whether there is fracture or wear crack, and whether the COF is burnt.

2. #Confirm whether the VAA is normal (normally about 17V). If abnormal, disconnect the RP32 to confirm whether it is caused by DC/DC loop or X-side COF: disconnect RP32, if the VAA is normal, the COF is bad, CO must be changed; COF can be Disconnect one by one to determine which NG disconnects RP32, VAA NG, try to change UP1; at the same time, confirm whether the continuity of the surrounding triode is OK.

3. #Confirm whether the RSDS value is correct, normal RSDS is about 1.2v, and the signal difference is about 200mV; At the same time, we can confirm the resistance between RSDS signal (normal 100 or 50 ohms) and RSDS resistance to ground. If the voltage is NG, check if the ASIC and X-COF are hot.

2. #Confirm VGH/VGL voltage (about 30V VGH and -6v VGL), and confirm whether it is DC/DC loop NG or COF IC NG; The corresponding resistance of disconnected VGH and VGL can determine whether it is a DC/DC problem or a COF-IC problem. If it is DC/DC NG, try to replace UP1 or confirm whether the corresponding transistor is OK.

3. #Confirm whether the gate IC is OK. There is a signal test point on the back of COG IC, which can scrape the green paint for measurement confirmation; Or cut COF halfway from G3. If there is a gate-ic problem, which IC fault can be confirmed.

B. Confirm VAA resistance to ground at VAA test point of R plate (A short circuit usually occurs), disconnect the corresponding capacitance of the following 3 COF, and confirm VAA resistance to the ground again. If OK, replace the capacitor, if NG, replace COF. If VAA is still NG, confirm DC/DC loop as all models.

3. #Shaking module, if vertical lines disappear or reappear, then it can be judged that the possible cause is COF pin broken, and the crease should be found under the OM microscope.

4. #Press the LCD glass side of the panel, if the vertical lines disappear or reappear, it can be judged that the cause of poor contact, OM checking should be able to find the poor contact.

5. #If there is no display change in pressing, confirm whether ITO is damaged under the OM microscope, or pin signal waveform corresponding to needle COF.

This article analyzes and introduces Samsung screens, Chi Mei and other screens. It mainly explains the function and composition of the side board, the circuit introduction of the side board (T-CON board), how to identify the representative symbols of the LCD screens of various manufacturers, and the common problems on the side board. Analysis, analysis of maintenance ideas for the side board part and analysis of maintenance cases. 1. The role and composition of the side boardThe information transmission between the main board and the screen body mainly includes the T-CON circuit, the side board and the COF. The latter two are the signal link lines, which are the link between the OC and the PCB, so Focus on the principle and maintenance of T-CON circuit. According to the different manufacturer’s screen design, it mainly includes the following forms:

This is a traditional circuit combination form, a single edge strip is used by most manufacturers, and the failure rate is also the highest, especially for LG’s edge strips, as long as the water enters, the note must be replaced, and the COF will be damaged in serious cases. The LVDS signal generated by the main board is sent to the TCON board for processing and conversion into various control signals (STV, CKV, STH, CKH, POL) and image data signals (RSDS) required. Add to the OC in parallel to present the image.

STV, CKV, STH, CKH, POL and image data signal (RSDS) to the side board, generally use flat cable to enter the side board. Many of the current integrated boards use this form, which brings inconvenience to maintenance.

The faults in the side strips are mainly manifested as: black screen, gray screen, blurred screen, vertical lines on the screen, vertical strips, etc.The main cause of the above-mentioned faults is caused by water in the side strips!

A. Causes of water ingress in the edge strips: Traditional CRT TVs are made of the entire glass cone with no connectors around. The current LCD screens use TAB elements, components, and COF to connect with the PCB board.The user still wipes the screen with a wet cloth like CRT, it is easy to get water in, especially when the LG screen side board is inverted , The sidebar is below, the failure rate is particularly high. As long as the water enters the side board, it will corrode and seriously burn out the COF and OC. Because the user’s home is too tightly sealed and poorly ventilated in winter, it is easy to produce water vapor under the action of heating, which flows to the side along the screen On the board. In summer, under the drive of air conditioning, it is easy to cause water in the edge strips. Especially in the south, it is wet and humid, and the failure rate of the edge strips is higher. Household cleaning is also an important link that causes water to enter the side strips. There are also reasons such as children playing with water guns and installing TVs under the air conditioner, etc., which may cause water to enter the screen.

The maintenance idea of the side board part analyzes the gray screen, black screen or abnormal screen light-emitting maintenance methods: when the LCD screen has the edge strips, the main manifestations are the following situations: 1. The TV can be watched normally, but occasionally the grating side is bad. The phenomenon can be normal in an instant, and it is generally difficult to find. 2. The left or right grating appears on the TV screen. .3. The backlight is bright and the screen is not bright. Maintenance method: For the fault that the backlight is bright and the screen is not bright, you should first measure whether the logic board LVDS power supply 12 volts is normal. There are two situations at this time: (1) Normal. (2) The fuse has blown. If 12 volts is normal, you should measure the relevant voltages such as VCOMVGH, VGL, and focus on measuring the output voltage VG1-VG21. If it is still abnormal, the logic board is damaged. If it is normal, there is no doubt that water has entered the side board. For the open circuit fault of the fuse on the logic board, it is not allowed to replace the fuse or directly short-circuit with a wire. The resistance value of the two ends of the fuse to the ground should be measured. If there is a short-circuit to ground, please check the cause. If the resistance to ground is large, it means that there is no short-circuit problem. You should disconnect the flexible cable between the logic board and the edge strip and replace the fuse. If it is normal at 12 volts, it means the LCD screen Water in. At this time, you can connect the two flexible cables from the logic board to the side board only one way to determine the position of the water inlet.
