Hi, all
I have a Visio VO320E TV that has no picture. When turned on Visio sigh in the front turns from yellow to white, but nothing else happens. I have read the forum and someone who was fixing his Visio pointed to specific components on the main board. I have located similar components on my board and took readings with power off/power on.
Here are the readings:
U2: 0.44V 0v 0v / 1.71V 0v -1.27
markings on component: L373 G1117
U7: 0V leg cut 0.43v / 1.27v leg cut 1.71v
markings on component: L323 G1084
U9: 0.43v 0v 0v / 2.5v 0v 1.27v
markings on component: L373 G1117
U11: 0v 0v 0v / 1.78v 0 0
markings MC 7805CT
I suspect that the linear voltage regulator U11 is not working.
Any ideas what may be wrong with the TV?
