Magnavox 42mf230a/37
it just stopped working last week...
no picture no sound
led is red, push power button on remote or tv and led turns blue... have to unplug to turn off
checked the y-sus and buffers for short both passed as non-short
found a bulging cap on the y-sus and replaced it (no change)
started checking voltages today...
1. Check PowerSTB5V（U516 3PIN）
Voltage: 5V (shows 4.95v)
2. Check the REL-SW state of power IO
interface，
High Voltage：Turn on
Low Voltage：Standby...Last edited by 84TAVeRT; 01-24-2013, 09:02 PM.
