The LA7848 is a vertical deflection plus EW driver IC for high image quality TV and CRT displays that supports the use
of a bus control system signal-processing IC. The sawtooth waveform from the bus control system signal-processing IC
can directly drive the deflection yoke (including the DC component). The LA7848 also provides a parabolic waveform
output that can similarly be used to drive the diode modulator block.

Functions
- Built-in pump-up circuit for low power dissipation.
- Vertical output circuit.
- Excellent crossover characteristics.

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.

We recommend matching the part number on your original part with the part number listed on this page to ensure compatibility.

While matching your model number is a great start, many models use variations of each part and they're not always interchangeable.

We include brief instructions in red text on some listings (also displayed below without the red font). Please look for these instructions to confirm any important info that you'll need to identify on your original part. Additionally, we highlight the part number in our photos.

Please don't hesitate to contact us with any questions. We're here to help!
