If your TCL TV has power but no picture, won't turn on, or keeps restarting, the main board is often the bad actor.

This replacement board, part number 30800-000498, is a direct swap for several TCL models including the 43S45, 43S451, 43S455, 55S41R, 55S451, 65S41, 65S41R, and 65S455.

The board number is 40-MR17T5-MAB2HG, so if that matches what you're pulling out, you're in the right place.

It's a genuine OEM-compatible board, not some cheap knockoff, so you're getting the same quality as the original.

The seller is US-based and ships quickly to 42 states, so you won't be waiting forever.

Plus, there's a one-year warranty on the part, which gives you peace of mind.

Just make sure your specific model is on the compatibility list before ordering—most 43, 55, and 65-inch TCL sets from this series are covered.

Replacing a main board is a moderately DIY-friendly job: unplug the TV, remove the back panel, disconnect the cables from the old board (take photos so you remember where everything goes), swap in the new one, and reassemble.

It's way cheaper than buying a new TV and usually gets your set back to perfect working order.
