Vizio VW42L Problem or No Problem??
I initially had tv picture rapidly flashing as though refresh rate had been reduced. Everything else was working. Turned set off, then on, after very short time trouble repeated. AMBER logo when off. Searched forums for clues. Replaced c421 on power board, a 470mf electrolytic. Did not find any other caps that were bulged so did not inspect any other boards for damage. Turned set on and it worked great with Logo operating normally. Set failed after 18 hours with same raster flashing. The cap I had replaced was bulging and 3 of the 4 470mf caps on the master and slave boards were also bulging so I replaced all four of them and the one on the power board that I had replaced before. The set has been turned successfully on and off several times since these last repairs with only one anomally. The Logo is is NOT Amber in the off mode. Yet the remote and side buttons operate normally. Can someone please help me resolve why the lack of amber? As of yet I have not removed and inspected the main board caps. Is there somthing I should be looking at on it which will give me the same symptoms. My logical conclusion is that the amber led is defective since the remote and side puchbuttons are performing as though the set standby power appears to be there for power to be turned on.
