Frequently Asked Questions

Q: Is it worth fixing a 3-year-old TV?

A: Often, yes. If the issue is a backlight failure, power board, or HDMI port, repair costs are typically 40-60% of buying a new unit. We provide a clear quote after diagnosis. If it's not economical, we'll tell you straight up.

Q: Can you repair a cracked TV screen?

A: Unfortunately, cracked panels are rarely repairable. The cost of a new panel often exceeds the price of a new TV. However, we can diagnose if the issue is actually the T-Con board or backlight, which are repairable.

Q: How much does it cost to fix my TV's backlight?

A: We start with a $60 diagnostic fee. This fee is 100% applied to the repair cost if you proceed. If the backlight is not fixable or the repair isn't economical, you only pay the $60 diagnostic fee. We provide a clear quote before any work begins.

Q: How long does a TV repair take?

A: Simple fixes (HDMI port, power board) take 1-2 days. Board-level repairs (backlights, logic boards) typically take 2-4 days depending on part availability and the complexity of the fault. We keep you updated throughout the process.

Q: Do you offer a warranty on TV repairs?

A: We don't sell extended warranties, but we stand by our work. If the specific component we replaced fails within 90 days, we'll fix it again at no charge. We believe in quality soldering and honest diagnostics.
