I know this post was a while ago, but I stumbled upon a solution to my tv just recently. I don't know if this will work for everyone's tv, but I find it hard to believe that this would only fix my tv with the same issue.

I opened up my tv and found that the placement for the connection for the power cord is poorly designed. For one it is very loose. Two, I don't know much about circuit boards but the connector has 5 prongs. Two of which are part of the same piece to both, I think, to anchor it down and ground it (it looks like it's part of the actual ground wire.) and the other three which I assume power the board. Those three are not completely soldered on completely e.g. they have holes in the soldering. The last thing I noticed is the ground wire is crossing the board and touching one of the coils.

As my tv got worse it started making a "short" sound. When I opened it up, I removed the connector and insulated the wire more. Also, I anchored it down tighter using the two prong piece (just made it tighter by pushing it down more and folding the prongs against the board and soldering it). Last, I re-soldered the 3 prongs, completely covering them. Put the tv back together and viola...it came back on and no problems.

I hope this help and I hope this makes it around to all the people who have this tv. It"s not a bad tv just a poorly designed board.

Olevia LCD HDTV 242tfhd will not turn on.


See solution above (from John Adams) if that doesn't work it may be the power board which is available on ebay for $69 incl. shipping. Good luck.

What is the price of the main circuit?


Here is a link to the complete parts list for the OLEVIA 237T11 television:


http://www.shopjimmy.com/olevia-237-t11



And here is the direct link to the MAIN CIRCUIT BOARD for that model:


http://www.shopjimmy.com/olevia-sc0-p519201gmi4-main-board.htm



Unfortunately the above supplier appears to be currently out of stock for that particular part, although this should give you an approximate idea of what the standard asking price is for replacing that circuit board ($160 US).

Just keep searching the internet and on EBay for the exact circuit board PART NUMBER listed at the above site and you may find one somewhere else for less. The online inventory changes every day so you just have to keep checking back often.

Good luck.

Joe.

I just repaired this identical problem on the same model TV. You have a bad power supply (also known as an SMPS). The board is model FSP271-4F02, and is about $75. Unlike the main board for this TV, you can find the power board relatively easily. Try shopjimmy, for example. Replacing the board isn't too difficult if you have a reasonable mechanical ability, have some tools, and are careful.

Olevia 747i won't turn on, no blue led light? Help!


I would start with the power supply. Possibly a fuse. 9 times out of ten though if a fuse goes, something inside the set is causing the fuse to blow.
