I need to know whats wrong with this tv and how much it will cost to fix
The power light comes on but once you try to turn the tv on you will hera a weird sound like its going to turn on but you get nothing. It smells like something is burning when you do this. I took the back cover off. Excuse my lack of knowledge but the gadget on the circuit board that has focus and screen adjustment screws on it, is burnt. theres this thick piece of metal, that kind of looks like a magnet that is attached to the circuit board and goes right through this gadget piece i was talking about. Do you have any idea what im talking about?
Re: i need to know whats wrong with this tv and how much...
Sorry for not having an answer for you, but it seems like we are having the same problems... Ill let you know if I come up with anything while searching through the internet all day.. If poss could you do the same if u come up with anything... Thank you
p.s.-we should have gone with a diffent model, and Ive rarely ever watched mine.This is what happens when i get interested after 3 yrs.
have a great day!

Cost is relative. The higher your skill with electronics the less it will cost. You have failing electrolytic capacitors either in the power section or the inverter section or both. Any caps in these sections that look bulged at the top, or bulged/leaking at the bottom need to be replaced. The TV will get harder and harder to start up until one day it just won't. It's
not an expensive fix but let the tech know that you know whats wrong
but don't have the parts to fix it or something like that so that he
doesn't charge for a bunch of stuff that wasn't wrong.
It may be the power supply starting to go out. That can be inexpensive if you know how to solder and troubleshoot electronics, as you could replace a few components for a few dollars. If you have it repaired by a professional, it could become rather expensive.
Instead of just unplugging the TV, perform a power drain:
1. Unplug the product's power cable so the device is not grounded to the house.
2. Press and HOLD the product's own power button for 1 minute to drain the capacitors.
3. Plug the product back into a wall outlet and try to turn it on.
Note: This procedure works with battery operated devices as well so remove the batteries and
hold down it's power button. Electricity can remain in capacitors and on circuit boards
enough to prevent normal functionality. By clearing the residue electricity, your product
will have a fresh start and many times this will resolve a buggy or non-responsive device
that appears to be dead.
If the TV still won't turn on, then it appears something is wrong with it's mainboard since the TV is still receiving power because the standby light is still coming on. The cost of fixing an older TV's mainboard could be costly or impossible if the part is discontinued.
It could be caps around the power supply. If this is a LCD projection TV, it might be the color wheel.
I would call some TV repair places to see what they say. If it is a power supply issue, I cannot see it costing more than $50 to fix it. If it is a color wheel or something like that, the cost will be quite a bit higher.
