1pcs CA-888 12-18V LCD Universal Power Supply Board Module Switch Tube 300V For LCD Display TV Maintenance

Product Introduction

Chip Model: DM0465R

•Application Range: Only applicable to 15-24 inch LCD devices

•Output Voltage: 12V, 5V (a voltage error of ±0.5V is acceptable)

•Purpose: Solve the power failure repair problem of 15-21 inch LCD monitors. The power board of LCD monitors has a relatively high damage rate, among which damage to power driver chips, high-power power switch tubes, sampling resistors and other components is the most common; due to the wide variety of models and types of these components, repair is often impossible due to the lack of identical spare parts, and this module can effectively solve this problem.

Usage Method

Remove the power chip (usually 8-pin) and switch tube (MOS tube) from the original board

⒈Check whether the 300V capacitor and the capacitor at the load end are bulging. If there is a problem, replace them first

⒉Check whether there is a short circuit at the load end (such as AD board, high-voltage board, etc.)

⒊Connect the corresponding lines of the module and carefully check to ensure there is no wrong connection (wrong ⒋connection may cause the module to explode)

⒌Install the module at the position of the original heat sink, pay attention to insulation and avoid short circuit

⒍After power-on, measure whether the voltage is output normally. If there is no output, the cause needs to be investigated
