Title: Firmware change update on Sony KDL-50W800C — unit runs hot after update
Body:
After the latest firmware update on my Sony KDL-50W800C, the TV runs noticeably hotter than before — especially near the bottom rear panel and around the heatsink area. Prior to the update, heat was minimal even after several hours of use. Post-update, the chassis feels warm to the touch within 30 minutes, even with standard HD content (no HDR or heavy processing).
Firmware version shown: PKG3.xxx.xxxxNA (latest as of [insert date]).
No changes to ambient temperature or ventilation. Factory reset didn’t resolve. Downgrade not officially supported.

Yes, with caveats. The performance improvements are real, especially for WiFi and HDMI ARC stability. The snappier Android TV interface is a welcome change for a 9-year-old TV. Here’s a short piece tailored for your query
However, the increased thermal output is not a myth. If your KDL50W800C is in a bedroom or living room with good airflow, you likely won’t notice the extra heat except by touch. But if the TV is in a tight entertainment center, you might trigger thermal shutdowns on hot summer days.
Our recommendation: Wait 2–3 weeks after this article’s date. Sony often releases a "silent" hotfix (v6.404.0642) that addresses the thermal policy. Check the Sony support page for the letter suffix—"NAB" and "EUB" are safe; "NAA" was the problematic hot run. If you see "NAC" or "EUC," that’s the revised cooler version.
