My olevia 42 in power doesnot come on. blue light was on when I pushed power to turn on tv. Blue light went out but tv did not come on. Blue light didn't not come back on. Television was working good. I have had television for 3 years.Checked back of set power switch, switched it off and on nothing happened, unplugged set and left unplugged for 2 hours power didn't return. I would like to find out what the problem to my set could be and is my set repairable or would it be cheaper to get a new television.

You need to get the set checked out by a qualified technician. You could either have a problem with the power supply board or the main board. The set needs to be diagnosed to tell which board is causing the problem

My Olevia 42" television is several years old. In March of 2012, the infamous "TV will not power on" problem started.

The blue LED light on the front of the TV would go off for a split second, then light up again. The television would not start.

If you are handy with small tools and a soldering iron, you can change the capacitors on the power supply. My Olevia is a model 542-B11.

I bought the repair kit off eBay from seller: sghill99

As of this writing, the seller has sold 37 of these kits. The title of the auction is: Repair Kit, Olevia 542-B11, LCD TV, Capacitors

And if the url is still active, it is: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=230554940338&ssPageName=ADME:L:OC:US:3160

I made the repairs in March 2012 and it is now August 2012 and the television is still working great. It is turned on and off several times every day.

Same happened with my Olevia 540-B11. You can probably find the details of how to disassemble the TV somewhere online. The problem is poor stress-relief on the cables that plug into the secondary (low voltage) side of the power circuit board (PCB). Once the back is removed you'll find the PCB on the left side with three cables connected to the very top of the board. These cables plug into four clips, 3 horizontal clips side-by-side at the top and one vertical clip on the left side. Unplug these cables, remove the PCB and re-solder the sockets (there are approximately 40 solder points on the back of the board). Reassemble your TV and it'll work just fine.

The issue you are having is your power supply

Thank you

If the tv is infact turning on eventhough the power light isnt, its the bulb for the powerlight itself

The tv have a Tuner board problems,this is the board,that take in the broscasting signal cable.Tries unplug,replug about an hour later.The tv should reset it self and work.Not than tries websites like Shopjimmy.com,Ebay.com to buy a refurbish Tuner board for the replacement.

Your power supply module may have gone out.

When my tv did this I unplugged power waited ten seconds and replugged it worked.

Check out power supply module first, it sounds like you are only getting 5v standby voltage. Look for bad soldering works or bad capacitors.:

Sounds like the power supply.
