Repair Journal | Mitsubishi LT-40153

Welcome to my very first REPAIR JOURNAL! I am constantly receiving jobs involving TV's and miscellaneous other consumer electronics. When you see the "REPAIR JOURNAL" tag anywhere on this blog, know that it is in relation to a specific experience with a specific model. This is NOT a tutorial and none of this should be considered a blanket statement or a fix that will work 100% of the time. Everything is situation based. That said, the tips and tricks found in REPAIR JOURNALS are meant to enhance your understanding of what may or may not work and will help you build your knowledge base in relation to general repair.

MITSUBISHI LT-40153 | LCD TV

SYMPTOMS: No audio. Video OK.
DIAGNOSIS: The set's issue is with the audio signal. In an LCD TV, the signal processing is handled by the MAIN PCB (motherboard). That is where all the inputs are (i.e. component video, composite video, VGA, HDMI, etc.), so it handles the audio and video signals, hence why we suspect it is the culprit in this case.
SOLUTION: I simply ordered a new MAIN PCB and installed it. Works like a charm.

For TV parts, try out eBay, ShopJimmy, and Encompass Parts. Need help finding the correct part? Let me know. I'll do my best to help you find a budget-friendly solution.
