What is an IC?

IC stands for “integrated circuit” and it’s a set of electronic circuits on one small, flat piece (or “chip”) of semiconductor material, usually silicon. Large numbers of tiny MOSFETs (”metal-oxide-semiconductor field-effect transistors) integrate into the small chip.

Which symptoms does an IC fix in a TV?

•  Since a lot of symptoms could be the result of a failed or defective IC, please refer to any symptoms listed on this page or contact your local TV technician.

*These are helpful tips to get you started and don’t represent accurate diagnoses for every TV model and failure. If you’re unsure of your diagnosis, we recommend checking out our YouTube channel or reaching out to a local TV technician for assistance.

How easy is it to replace an IC?

You’ll need to have soldering experience to replace an IC on a board. If you don’t have that technical background, we suggest replacing the board instead.
