TV Repair FAQs: Expert Answers to Common Questions

Costs vary by fault type, television brand, screen size, and the technician's location. General ranges for common repairs:

• Diagnostic inspection: $50–$100
• Power supply repair: $120–$260
• Backlight replacement: $150–$320
• T-con board replacement: $100–$250
• Main board replacement: $150–$400
• Screen panel replacement: $400–$1,500+

The diagnostic fee is often waived or credited toward the repair if you proceed. Always confirm this when booking.

The standard guideline is that repair is worth pursuing if the total cost is less than 50% of what a comparable replacement would cost. For a five-year-old 55-inch LED television that might be replaced for $700, a repair costing $200–$300 is almost always the better choice. For budget televisions under $400 new, the economics of repair are less favourable for major faults. A technician can provide an accurate assessment once the fault is diagnosed.

This depends on the individual shop's policy. Many reputable Canadian repair services waive the diagnostic fee if you proceed with the repair; others charge it regardless. Always confirm the policy before dropping off or booking an in-home visit. Consumer protection laws in most Canadian provinces require service providers to inform you of any charges before work begins.

For common faults where parts are in stock, many repairs are completed within 1–3 business days. More complex repairs, or those requiring parts to be ordered, may take 5–10 business days. OLED panel repairs or replacements can take longer due to more limited parts supply. Ask for an estimated timeline when you drop off or book.

For televisions over 55 inches, or those wall-mounted, in-home service is strongly recommended. Transporting a large flat-panel television is risky and may cause additional damage. For smaller TVs, shop-based repair is often faster and may allow access to more diagnostic equipment. Many Canadian repair providers now offer both options.

Reputable shops use new, manufacturer-compatible components. Some use refurbished parts for older models where new parts are unavailable — this is acceptable practice when disclosed. Ask specifically about part sourcing before authorizing repairs, particularly for premium televisions. Manufacturer-authorized service centres are required to use genuine parts for warranty-covered repairs.

Reputable technicians typically offer 90 days to one year warranty on parts and labour. Some specialize in particular brands and offer extended warranty on their work as a competitive differentiator. A repair service that offers no warranty is a significant caution flag. Get the warranty terms in writing before the repair is completed.

Under Canadian consumer protection legislation, you have the right to have the specific fault described in your estimate repaired. If a repair fails to resolve the stated fault and the shop cannot correct it within a reasonable timeframe, you are generally entitled to a refund of the repair cost. Contact your provincial consumer protection office if a dispute arises. In Ontario, the Consumer Protection Act applies; other provinces have equivalent legislation.

If your television is within the manufacturer's standard warranty period (typically one year for most brands in Canada), contact the manufacturer directly to initiate a warranty claim. Most major brands — including Samsung, LG, and Sony — have authorized service centres in Canada's major cities. Using an independent repair shop for a warranty-covered repair may void the remaining warranty.

A black screen with working audio is most commonly caused by a backlight failure (for LED televisions), a T-con board fault, or a loose internal cable. Backlight failures are among the most common and most cost-effective repairs in LED televisions. A technician can confirm the cause with a simple test using a torch — if you can see a faint image when shining a bright light at the screen, the backlight is the likely culprit.

Lines on the screen are typically caused by a T-con board fault, a main board issue, or a loose panel cable — all of which are generally repairable at reasonable cost. If the lines are caused by physical panel damage (impact), repair is less straightforward and may not be economical. A diagnostic will confirm the cause.
