Question about Vizio VO47L 47 in. LCD TV
It may be a bad system circuit board. Is it fixable? Yes, but at an expense, all depending on exactly
what is wrong. I predict the problem to be the horizontal deflection
amplifier and the high voltage generator (called the flyback
transformer). The cost of repair is likely to exceed $150.
Is it worth fixing? Probably not because the set is nearing the end of its normal life span anyway. Also, the cost of repair is about the same as a new set of equal value. Now might be an opportunity to step up to one of those new fangled sets with wide screen and HD compatibility - although they are still quite expensive!
Did the electrical work being done cause this? It could have, but I doubt it. When ever I go away or know that I am not going to be using a tv for a while, I always unplug it. Little do most people know that even though the set is OFF, it is still ON a little bit. The remote receiver must always be on so that it can receive the signal from the remote commander when you want to watch tv. Therefore, it is always possible for some backward trending pulse to get into the set. For example, an electrical storm can destroy a tv set if it is plugged in - even though it is OFF. But if it is unplugged, it will not be harmed.
If this is the tv with the ssb pannel it probibly is bad,. if it is that board is not repairable, and can cost about $300.00 ish .
