Check to see if same on all inputs and also test by using a DVD player.

One of two general things is wrong here : either you have a short at the input section of the power supply--bridge should block it from getting to main input filters==== or if fuse was replaced it is wrong=explanation?Most of these sets use a special fuse--if a surge or even a problem takes it out the fuse must be replaced with the CORRECT one, amperage and voltage rating aside many of the fuses are thermal or special slow blow types---put a generic fuse of proper rating in and it can pop instantly for no reason.Other than that it has to be between the input for the power cord and the output of the bridge or even further down on primary side of actual power supply===usually another diode is in line after the bridge will prevent it getting to the main input filters.If reference to Steve is directed at me that is my name---pretty simple repair and as far as that bridge goes if it is attached to a a heat sink you better remove the sink and look at the bridge with your eyes---seen more than a few where it tested good but was fractured at heat sink--when power hits it can arc right to the metal and fuse goes instantly.You have a very limited number of possible parts (other than wrong fuse) that can cause this====try to isolate issue with simple tests.............

The trouble of your lcd tv is in the power supply. Try to remove the back cover of your lcd tv but be sure to unplug it. Then try to follow the ac cord it will lead you to the power supply, the ac cord is connected in the pcb you will see a line in the pcb try to trace the line and you will see the fuse their are many types of fuse the common fuse are the glass type and the ceramic type.

A good idea here would be to take some digital photos---find a photo sharing site on the net and post them there.copy the URL or location of them and post it here---seeing what it looks like might point to where the problem is.

I would start with looking at the 12 or 15vdc source form the power supply. I would surely look for capacitors with bubbled tops.

Check and replace the power supply regulator board.

Refer its user manual [specifications] and see whether the tV can process digital signals. If it has ditgital processor inside, you can see it there in its specifications.

in the main power supply where the power cord for the set goes.

If you are trying to connect it to some external speakers be careful as you can damage the set by doing that.

Your panel went bad. It is not cost effective to fix. I don't think you could get a panel any way.

The first word is "Carefully". LCD and Plasma screens are easily damaged and must be laid face down on a surface that supports the frame all around the screen and does not allow the screen to touch the surface it is laying on. ONE WRONG MOVE OR PRESSURE EXERTED DOWN AND THE SET WILL BE HISTORY--DAMAGE TO THE PANEL IS FATAL AND THAT PART (called the display panel) always costs more than the set did if it is even available. With set carefully face down locate if the set has a base on it the bolts that secure the base to the set and remove them. From here it is usually just a case of removing screws and noting that the different sizes used go in different places--some will be machine bolts with fine threads and others self taping---don't get them mixed up. When doing this or whatever you are doing inside exert no downward pressure on the unit to avoid destroying the panel and hence the set. If you have a specific reason for opening the set let me know--happy to suggest options before you take it apart.

if you look at the back of the television there are usually a few small skrews that need to be delicately removed and carefully looked after. after all of the small screws have been removed the back can probably be removed carefully.hope this helps!

Set listed is a Olevia, what are you attempting to do?

Hi Beth , we are having the same problem. Were you able to fix?
