PCBs & Main Board Assemblies for Television Repairs
The TV main PCB is a crucial component that manages video, audio, and control signals in modern televisions. It ensures smooth operation by coordinating various inputs while managing power distribution for stable performance.
Common signs of a failing TV main PCB include power issues, screen distortion, crashes, or unresponsive controls. The main board processes video, audio, and input signals. The logic board coordinates internal communication, the power regulator supplies stable voltage, and the signal processor handles video and audio playback.
Main PCBs typically operate within a voltage range of 110V to 240V. Each board includes integrated power regulators, high-speed signal processors, and multiple input/output connectors designed for model-specific compatibility.
At HnK Parts, we offer high-quality TV main PCBs and related parts such as power regulators, signal processors, and connector cables from trusted brands like Philips, Samsung, LG, and Hisense. Quality-tested parts at great prices to keep your TV running smoothly.

What is the difference between a PCB and a main board?
A PCB (printed circuit board) holds and connects electronic components. The main board, or motherboard, is a specific PCB in a TV that controls inputs, processes signals, and communicates with other parts.
How can I tell if the power board in my television has failed?
If your TV power board is bad, common signs include the TV not powering on at all, frequent shutdowns or restarts, no standby light, or unusual noises like buzzing or clicking. Sometimes, the TV might turn on briefly and then shut off immediately.
Which symptoms indicate a failing TV main board?
Symptoms include no power, no picture or sound, distorted images, random shutdowns, and unresponsive remote or control buttons.
Where can I buy TV main boards or PCBs?
TV main boards and PCBs can be purchased from trusted part suppliers like HnK Parts,
which offer model-specific replacements from brands such as Philips, Samsung, LG, and Hisense.
Why is my TV screen flickering or freezing?
Screen flickering or freezing is often caused by a faulty logic board or timing control issue in the main PCB system.
