Hi. Got a Magnavox L01-1UAC-7638. Came in, shorted HOT. Ordered Mat Elec kit
(HOT, 2 elec caps and 2 driver transistors), put in, lasted 2 weeks. Put
another kit in 3 days ago (thinking maybe a bum part) and HOT died in
minutes. Nothing seemed overly hot, just dropped in chirp from power supply.
No oddball solder joints or anything else obvious. Runs perfectly with great
picture and sound, then dies with no warning.

Flyback perhaps?

Cheers, Danny
