You have shorted power transistor or mosfet on power supply that need to be replace however this need a soldering skills and electronic background if you don't have skills its better if you replace the whole power supply board.

SOURCE: My 50

if the fuse was at the or near the AC plug chances are your got a power surge, if you did you got very lucky the fuse was there you might want to get a surge protector on the set ... But sometime you get just a defective fuse as long as the set is working I would not worry about it

SOURCE: Watching the TV and heard

The power suply unit may be dead......if the fuse blows instantly it means that the main input is short.
possible parts damaged :the diodes from the mains, the power tranzistor and the ic from the primary part and other components around them.
First unplug the tv, unload the mains capacitor (using a light bulb) check all the diodes from the rectifing bridge, check for any shortened semiconductors or blow resistors.


BE VERRY CAREFUL !!! THERE IS A RISK OF ELECTRIC SHOCK ,IF U DON"T KONW ANY ELECTRONICS TAKE IT TO A SPECIALIST

Olevia 537 keeps turning off


I see so many here with no sound/nopicture issues:

ISSUES:

1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.

Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have to buyand try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over.If set is opened at least look for puffed up and bad caps like in thisphoto.4_23_2012_5_08_51_pm.jpg

Need a Power supply for a LT26HVX Olevia LCD


That is because no one knows how to troubleshoot to the component level anymore in this "lowest repairable unit" world we live in! Throw it away and buy a well know TV set. Another item for the land fill....Shame! Sorry as it is, just a shame.
