How much does projector power board repair cost in India?
Short answer: Capacitor swap on the power board costs ₹1,500–₹4,000. A more extensive SMPS repair with failed MOSFETs (power switching transistors) or regulator ICs costs ₹2,500–₹7,000. Full board replacement, when component-level repair is not viable, costs ₹5,000–₹14,000. All work begins with a ₹149 doorstep diagnosis that includes a multimeter voltage test of the power rails before any part is ordered.
Three repair tiers for projector power boards
Tier 1: Capacitor replacement — the most common fix
Electrolytic capacitors on the power board age faster than almost any other component in a projector. In India’s climate, ambient temperatures can exceed 40°C in offices without adequate air conditioning; ceiling-mounted projectors run hotter still. Heat is the primary enemy of capacitors — a 10°C rise halves capacitor life. Bulging or leaking capacitors on the power board are the single most common cause of projectors that fail to start after 4–6 years of regular use. The correct repair is to replace the entire capacitor population in the affected voltage tier with 105°C-rated industrial-grade units — not just the visibly bulging ones. Cost: ₹1,500–₹4,000.
Tier 2: MOSFET or regulator IC replacement
The SMPS circuit uses MOSFET transistors (semiconductor switching devices) to chop the AC supply at high frequency and regulate output DC voltages. A power surge — common during power restoration after a cut in Indian offices and schools — can instantly destroy these components. A burned MOSFET presents as: projector completely dead (no LED at all), a faint burning smell near the power board, or a blown fuse that reblows immediately on replacement. Replacing the failed MOSFET(s) and the fuse costs ₹2,500–₹7,000. This is significantly cheaper than a full board, and the repair is reliable when done at component level. See the projector won’t power on service page for the full diagnostic process.
Tier 3: Full board replacement
When the board has multiple cascaded failures — burned traces, damaged PCB substrate, or more than 3–4 failed components — component-level repair becomes uneconomic. Full board replacement is the correct path at that stage. Board pricing in India ranges from ₹5,000 for budget Acer or InFocus models to ₹14,000 for Sony or NEC installation projectors. Availability for models over 8 years old can require sourcing from donor units. For related repair context, see the motherboard repair cost guide and the lamp cost guide for co-occurring faults after a power surge.
The India angle: power cuts and the case for a UPS
The transient voltage spike when mains power returns after a cut is the projector’s most common enemy in India. A UPS (Uninterruptible Power Supply) or a voltage stabiliser with surge protection absorbs these spikes before they reach the projector power board. For school and office projectors running 5+ hours daily, a ₹3,000–₹6,000 UPS pays for itself the first time it prevents a ₹5,000 power board repair. Always connect projectors in unstable power areas through a UPS or stabiliser.
A note from the PRW Engineer Team
The fastest diagnostic step for a completely dead projector is a multimeter check of the DC output rails from the power board. If the 12V, 5V, and 3.3V rails are all absent, the board is the fault. If any rail is present, the fault is downstream. A complete zero-response projector is a power board problem until proven otherwise.
