How much can I get for my 4K TV?
It depends on the panel type, screen size, age, and condition. Premium 4K OLED, Micro RGB, and RGB Mini LED sets typically bring the highest offers. Bring it in for a free, no-obligation assessment.
How do I know what panel my TV has?
Check your TV’s model number or original box, which usually lists OLED, QLED, Mini LED, or RGB technology. If you’re still unsure, bring it in and we’ll identify the panel for you.

Do I need to bring the remote or stand?
It helps to bring the remote, stand, and power cable if you have them, as a complete set can increase your offer. But bring your TV in either way and we’ll make you an offer.
