LG AL-04CA TV Board
 |
LG AL‑04CA is the main input signal processing board used on LG 32″ LCD TVs such as the 32LX3DC/4DC series. Known failure modes for this board include power supply IC failures, burnt capacitors or solder bridges on the HDMI/AV input sections, and degradation of the integrated tuner module (often indicated by “no signal” or “HDMI handshake error”). Typical repair steps are: verify that the 12 V/5 V rail outputs from the power board match spec; inspect the board for obvious burn marks or cracked components around the HDMI, AV, and tuner ICs; and check the serial‑bus (I²C) communication with the tuner chip for proper address response.[oss-gpt-20b] |
