My Olevia 37" LCD HDTV suddenly will not turn on.

ok, does the entire TV shut off or just the screen?

tv goes blue everyday afte use.....i always have to turn off tv to get tv.......after 5 min.....

tried to connect again the supply for main board and disconnect the supply for the inverter board of back light. and turn on the tv, if the indicator stay the inventer board was the cause of voltage drop at the power supply board.

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.

jtoddweaver, Check out some YOUTUBE videos of lcd monitor disassembly and lcd monitor repair so you will know what you are looking for that is bad on your unit's "switch-mode-power-supply" printed circuit board. If you do the repair to the board, please document your "tear-down" with video or digital still pictures so you can complain to OLEVIA about poor quality capacitors they installed on power supply and also aid in the reassembly process. Do some reading in the fixya profiles of "budmrtn" "buddymc" "12fixlouie" and follow links you find there. Bye for now 12fixlouie

You can try to troubelshoot to component level by looking for bad caps first, right now the standby 5vdc is not working, or you can buy new power supply:

Most likely the CCFL inverter has been the problem all along....

It is either the fluorescent backlight source for the LCD panel or its associated power supply failing.

You need to take the unit to an authorized repair shop to have it
check and correct it , looks like the power supply section got affected by the sudden change of voltage and damaged an internal part, hope this helps , AJ

I would check the capacitors on the power inverter most problems with LCDs can be attributed to that or the backlight
