Westinghouse L1928NV Monitor Flicker

Nov 23, 2013 2 Replies

Monitor has begun to flicker slightly. Annoying. I replaced 4 CapXon capacitors that were buldging with Rubycons. Still has the slight flicker. Is there a commonly accpeted next step to check? Thank you.


CCFL joint in one corner emits "sizzling" sounds. Hard to see how to access without destroying the screen. Any one have hints on getting at the CCFL on a 19 unch "Chi Mei" screen? Thanks.

I wiggled the screen apart. One lead immediately fell off. I assume this was the problem. Bulb not blackened so I made a splint for the short stub on the CCFL and resoldered the lead. Reassembeled but no joy. Unit fires up and goes to protected mode in a few seconds. Testing individually, the bulbs light for a few seconds as well. So I think bulb is now good. I'm guessing load is imbalanced as the inverted circuit now hisses softly before turning off. The hiss is new. The leads emerge through a small opening in the metal casing. I wrapped in tape but the fit is tight. Maybe excessive leakage? Should I just redo this and hope for a better result? Suggestions? Thanks.
