Try this first. Not sure, but most Vizio menus within the last 4 years should be close enough to navigate through. It's a little tricky to get to. You highlight picture, then you hit the right arrow to bring up the Picture menu. Go down to Advanced Video (one above Reset Picture Mode) and hit the right arrow again to bring up another submenu. Go down to Backlight Control. There are three options: OFF, DCR and OPC. Both DCR and OPC seem to cause a problem. Try turning this feature to "OFF" and see if the the problem goes away

It sounds like to me theat the new lamp is faulty. If there is any pieces of glass in the lamp compartment, remove them so they will not travel and get wedged in places they should'nt be.
Hope this helps,
that is a common problem with that model you will need the v26 power pwb repair kit and the V26 FMT pwb repair kit. You can get both kits at the following link which includes the replacement capacitors and instructions on where the capacitors are located. Heres the link. http://servicemanuals.vstore.ca/
