Question about Televison & Video
Posted by Anonymous on
If you are a tech in any aspect, try testing the power points Vs and Va voltages. If not present even with the other circuit boards disconnected the Vs is supposed to be 205v when disconnected like on my tv, it only had 12v and the Va which is supposed to read 56v was reading about 10v when the boards were connected (Y Buffers). With the boards disconnected the power supply will read high voltages, and when connected (try lower first, then try upper, then try together). If there is a voltage drop (significant) that particular board connected is the culprit. If the PSU doesn't read a large voltage like mentioned, try replacing the PSU first.

Unfortunately, what you're describing is a repair issue. You won't be able to address the problem with troubleshooting. There is a part inside the TV that needs to be replaced. If you're under warranty, this will cost you nothing. If you're not under warranty the cost will likely be a minimum of $200 parts and labor. However, be warned that the cost could be considerably higher.
