Question about LG 62SX4D 62" Television
Hi i have a lg rear projector tv we were given it by family friends and they said they were watching it one morning and the tv just turned off. when we try turning the tv on a white led light scrolls up and down and then two red lights come on at the top, the top one on constantly and the second on flashing. The people before us told us that the bulb just needed to be replaced but i don't want to go spending money or digging myself into a money pit.
Old technology, dump it. My work place at the airport just installed a 72" Samsung Ultra High Definition 4K flat television. Easily worth the $6,000 it cost.

well i know what the problem is... if your getting the white scroll and then the red light flashes but the fans are comming on and you got a new bulb the broblem is the ballast. i know cuz i had the same problem and a good friend of mine has a tv shop and i had him look at it but the good news is that its not that hard to change. if you try to go through LG thay wont be able to sell you the ballast if your just a coust. good news is that you can fined the ballast on ebay from easywaylamps its about $130.00 bucks shiped. bud news about is that thay are from china(it is where i got mine) but it works great and hasent gave me a broblem yet. if any one eles has the same problem and it was something eles.... PLEASE POST IT. i hope my info has been helpful to someone.... thanks Brad Ross of East Moline Illinois

Power supply switching regulator board inside your LG TV is faulty. There are more than 8 regulated supply rails emerges from that board, after switching regulation, which will enter to different sections of circuits in your Tv. one or tw of its output voltages are missing now, in which, voltage to sound card also will includes. In most cases, this section is replaced as card basis, rather than making "surgery" to it. Clicking noice you hear along with this is a clear indication that there is something short on that board. It will be difficult, even a trained technician to locate and rectify the fault on that board, because, most of the components on it is machine soldered, and cannot be desoldered or resoldered by normal soldereing techeniques. Moreover, some of the components in it are not easly available on open electronic spare part shops, as LG has some special transformeres of their own, which they won't deliver to the open market. So in my opinion, it is best to replace the card itslef with same type and number, Type and number will be printed on the card and can be noted. You must have testing equpments like, a good quality digital multimeter, soldering Iron, desoldering pump and the most is sound knoledge in digital electronics and enough patience. After replacement of the power board, there will have to do some adjustements, [service adjustments] to get the picture well defined.
If you have confidence and informe me by Fixya. I'll assist you. OK.
