Question about Westinghouse LTV-27W2 27 in. HD-Ready LCD Television
Posted by mcfly_lives on Nov 08, 2008
the tv was working fine wednesday. i turned it off, went to bed. thursday night, it wouldnt turn on at all. i unplugged it, tried again. nothing. pushed and held the power button, light came on in the front, but still no pic or sound. called westing house, they said could be inverter circut, but wasnt much help other than that. called a few tv repair shops, nobody works on lcd tv's. Best buy said they send it back to the manufacturer and then tell me if its worth fixing. searched inverter circuts and found they are fairly cheap (15 bucks). how easy is it to change that out? if that is not the issue, what else can i check to fix it? Comment by mcfly_lives, posted on Nov 08, 2008 to update this problem.... its a 27 inch westinghouse. model number LTV-27w2. i found a site that has the inverter circuts plus other parts, i just dont have any clue as to which part it may be that needs replacing. best as i can figure there are three main boards or circuits that can go bad. the inverter circuit, the back light and the power supply.
since the purple light comes on, im guessing its not the power supply. i think the back light is for the screen not the sound. best guess would be the inverter circuit, but im not sure what the inverter circuit does..?
MAIN BOARD IS BAD...THERE ARE TWO DIFFERENT MAIN BOARDS FOR THIS TV...IF S/N STARTS WITH W2702...USE P/N 5600110351...IF S/N STARTS WITH W2751...USE P/N 5600110493...PART CAN BE ORDERED FROM ANDREWS ELECTRONICS IN CALIFORNIA..YOU MAY CONSIDER TAKING THE SET TO A LOCAL REPAIR SHOP..

T-CON board, check the connections between the T-CON and the Main LOGIC board first (very rarely to be the logic board but not 100% for sure). Make sure to get the number as printed on the board since there are more than one version. http://www.shopjimmy.com/catalogsearch/result/?q=Westinghouse+LTV-27W2+

SOURCE: We have a LTV-27W2 television
They are METRIC screws, either M5 or M6, but get M4 too jsut incase, you can get tehm at HD or Lowe's for about 35cents each so you can get different length to try out, more likely to be about 1/2".
