Videocon AC Circuit / PCB Breakage Repair in Chennai
A burnt or faulty control PCB stops the AC responding correctly.
When the main printed circuit board (PCB) on a Videocon air conditioner suffers a electrical breakage or trace burnout, the unit loses its central control brain. Videocon split and window AC models rely heavily on their motherboard logic to regulate the compressor relay, process infrared signals from the remote, and direct indoor fan speeds. In Chennai’s hot and humid climate, voltage fluctuations and heavy usage cycles often cause the solder joints, capacitors, or power ICs on Videocon PCBs to overheat and fracture, leaving your unit completely unresponsive or stuck in an error loop.
Common Symptoms of Videocon PCB Failure- The Videocon AC indoor unit does not turn on at all, despite power active at the wall socket.
- Error codes such as E1, E2, or EC flashing continuously on the display panel.
- The indoor blower fan runs, but the outdoor compressor never triggers to start cooling.
- The AC turns off abruptly after a few minutes of operation and resets automatically.
- Unresponsive remote control signals even after replacing the remote batteries.
- Power Surges and Spikes: Sudden voltage spikes from the local Chennai grid burning out the primary transformer or varistor (MOV) on the Videocon PCB.
- Track/Trace Corrosion: High humidity and saline air corroding the delicate copper circuit traces on the board surface over time.
- Pest Intrusion: Geckos or insects entering the control box assembly and creating short circuits across high-voltage terminals.
- Component Fatigue: Aging electrolytic capacitors bulging or leaking, disrupting steady DC power supply to the microcontroller.
- Diagnostic Testing: Our field technicians test incoming power, transformer output voltage, and signal communication between indoor and outdoor units.
- Micro-Soldering & Component Repair: If the damage is localized, we replace burnt relays, blown fuses, damaged capacitors, or repair severed copper traces on site or in our workshop.
- Complete Module Replacement: For severely burnt logic boards, we source compatible Videocon circuit boards to ensure seamless restoration.
- Post-Repair Load Testing: We calibrate the sensor resistance, check compressor relay timing, and run the AC under full cooling load to confirm stability.

Frequently asked questions
Can a broken Videocon AC circuit board be repaired, or does it always need replacement?
Most Videocon AC circuit boards can be repaired by replacing blown fuses, varistors, relays, or repairing burnt copper tracks. Replacement is only required if the main microprocessor is burnt or if board corrosion is too severe.
What causes the PCB circuit to break down in Videocon ACs?
Frequent voltage fluctuations, power surges, moisture-induced corrosion in Chennai coastal areas, and short circuits caused by insects entering the indoor control box are the primary causes.
How long does it take to repair a Videocon AC PCB?
Minor component replacements and fuse fixes are typically completed within 1 to 2 hours at your home. Complex trace re-soldering or micro-repairs may take up to 24 hours if the board needs workshop servicing.
Does Janani Cool Care offer a warranty on Videocon AC PCB repairs?
Yes, all Videocon AC circuit board repairs and component replacements completed by Janani Cool Care come with a 30-day service warranty for your peace of mind.
