Common Epson projector faults
Dim or discoloured image
Lamp wear, polariser or LCD optical-path contamination may be involved.
Overheating
Blocked filters, dust, fan faults and thermal protection require inspection.
No power or shutdown
Power-supply, ballast or main-board diagnosis may be needed.
Common BenQ projector faults
White or black dots
On many DLP models, progressive dots can indicate a failing DMD chip.
Colour wheel symptoms
Unusual noise, colour flicker or shutdown can involve the colour wheel or sensing circuit.
Lamp and ballast faults
Failure to ignite, dim output and intermittent shutdown need lamp-system testing.
Indicative repair costs
Basic cleaning may start around ₹500, board-level work around ₹1,500, and DMD or optical repairs around ₹2,000. These are indicative starting points—not quotations. Model, parts and fault extent determine the final estimate.
Which brand is easier to repair?
Neither brand is universally easier. Repairability depends on model age, parts availability, prior tampering and the failed assembly. We diagnose first and request approval before paid repair.
