Seems like Vizio is a mistake. Mine did same thing, worked fine, slowly but surely failed to turn on (amber vizio light went completely dim), but being too busy to disconnect it (its our bed room TV) after about 2weeks the amber light grew brighter. On a whim I pressed power button on side of TV and after a couple of tries (flashed off/on repeatedly) the screen turned on! I knew I should have just left it powered on until it died, but I turned it off and I'm back to square 1. Time to buy another (brand) TV set. P.O.S.[/u]

Coming from a board manufacturing background I can tell you that in many cases, the use of BGA's (Ball Grid Array) IC's and FPGA's (Field Programmable Gate Arrays) makes it impractical to repair to board level.
Most tech's don't have the hot air soldering/desoldering equipment to properly replace BGA's and even if you get one installed, you need an x-ray machine to verify that all the balls soldered or did not short out. If you get that far, the new IC will be blank and it takes special equipment and the raw files to program the new IC. In some cases, the ability to program these boards are protected by the removal of JTAG or similar connecting portions of the PCB.

Nope. Technicians are all just board swappers now.

Anyone done repair on main board? no picture no sound

You can usually read the numbers on the thermister and cross it to an equivalent. Here is a site to try. http://www.nteinc.com/

I'm trying to repair a power supply (199AP) for this Visio 32" set and could find no problems, but no voltage at all comes out, not even the housekeeping 5v. Then noticed the thermister is cracked, so pulled that out. But now I can't figure out what to replace it with. Anybody know what thermister is used for 'NTC1' on the board? Or maybe there is a workaround?

Our TV went out after a very close lightening strick. I'm not sure if it actually got "hit," because everything else on the surge protector still works fine. However, the TV quit turning on. I don't want to pay the $85 for the ps and find out it still doesn't work. What are the chances that it is just the power supply?

A friend of mine was watching his L32HDTV10A a week ago when he heard a bang that he at first thought was a gunshot. Apparently it came from the Vizio since it immediately went dark and completely unresponsive. No lights. No LEDs. No sound.

Have tried unplugging for extended periods, replugging, holding power button while replugging, pressing green micro-switch (whatever that is for) on main circuit board. No change. No lights. I found the fuse on the power board and was hoping that it would be as simple as replacing it, but after removing and checking it the fuse seems to have continuity. I have examined all the caps on the power board and main board and see no sign of explosion -- or even bulging or leaking. (Wonder what caused the bang!)

I am much more familiar with computer hardware than with TV hardware, but I am guessing the problem is with the DPS-199APA/0500-0507-0180 power board. Looks like I would be able to pick up a used one on eBay for about $65, since new ones seem to be "out of stock" everywhere. Did find a rebuilt 0500-0507-0240R on partstore.com that claims to be compatible, so maybe that is a better choice -- just getting a little pricey at this point...

Any other suggestions on where to go from here? Thanks!

ICE3B1565 made by Infineon. But it may not be the only problem as someone posted earlier in the thread
