Question about Proscan PS27125 27" TV
My Proscan TV works fine right after I turn it on, but within about five minutes the picture disappears and is replaced by a horizontal white line acrosss the middle of the screen. The sound is unaffected. within a few minutes the picture may, (or may not!), reappear. This sequence of events is randomly repeated as long as the power is on. I love the set, but can't afford a repair shop's bill. I am good with tools and such, know a bit of electronics, and am perfectly willing to attempt any advanced repair procedure; it's either that or the TV goes unused and uselessly taking up valuable space in my garage. Thanks for any helpful advice.
You'll have to locate the vertical output IC which should be mounted onto a heatsink, then take out a good magnifier under the printed circuit board and examine the solder connections on the pins of that IC and resolder the ones that are cracked.
