Question about Olevia LT42HVi 42 in. LCD Television
took the advice from Toy_Ladi and bought a new power supply and
installed it. The good news is that the blue led came on which means
that the tv has power but the bad news is that the screen is not
turning on. I don't know what else could be wrong because the power
supply is new and we plugged everything in correctly. Please let us
know what else could be wrong. Thank you.
since you have changed the power supply and the TV is not displaying, then the next to check you the TV's line transformer.
There is a rubber pipe with a rubber head that enters into the tube of the TV. Trace this pipe down to the TV board and you will see the line transformer on the TV board. This transformer carries current into the TV tube. So its either this transformer is defective, or there is no current passing into/through it.
I believe the line transformer will solve the problem this time.
Note that this transformer stores high of current so wait till for some time before tampering with it.

There is a component in the TV which sends electrical currents to a first screen which excites the LCD and sends a signal to the second screen which creates the picture.I do not know the technical name for it other than to call it an emitter.That easily could have fried with either a short in something or a lightning strike which will trip a breaker.Excessive current.If you have a meter or test light and you can locate the output,check the meter from that to ground.My computer was fried in a lightning storm last year.When we bought a new one,we looked around for a REAL surge protector.The ones at regular stores for $5-$15 shouldn't even be allowed to be labelad as a surge protector.We ended up buying a Belkin.They are a little pricier but they back it up with a monetary guarantee.I think the smallest one they have is 6 outlets and is about $50 but guarantees at least $50k.I called to ask and no matter what is plugged in,if it fries from their product,they reimburse you for whatever you lost,no reciept needed.It costs more but I am much more happy to have that.
The screen could have fried,but seems less likely because LCD is a little more tolerant.Let me know how you do.Good luck! Greg
