I have a Maxent 42 inch plasma.When you turn it on, it flickers for 5 minutes then comes on.recently the flickering continues non stop and now is almost unwatchable.Any idea what I can do to fix this? I...
What is the Product Name or Model number of your Maxent 42" Plasma TV? If it is a MX-42X3, Model # P420542HM8, I think I can help you. I have encountered this exact same problem with 2 Maxent MX-42X3 Plasma
TV's. I found that C766, a 220uF, 16V surface-mount electrolytic
capacitor on the main board is bad. This capacitor is located just to
the left of the green multi-fin processor heat sink. This capacitor
will test good using capacitor meter or an ESR meter, but if you spray
it with Freeze-It with the power on, you will find out that this is the
problem! To get it out, I found I had to remove the little 10uF 16V
surface-mount capacitor just to the left of it. I then replaced these 2
capacitors with regular (radial), high-temperature, low-ESR capacitors.
I cut the leads short, and bent the ends out just a little bit so you
can solder them back onto the surface-mount pads. You can get these
parts from Digi-Key Corp. I used Digi-Key part # P12383-ND ($0.32) for
the 220uF capacitor, and P11212-ND ($0.30) for the 10uF capacitor. Both
of these capacitors are rated for 25V and high temperature, so they
won't go bad again. You can purchase surface mount capacitors there
too, but I find them very difficult to solder back into those locations
due to the tight placement of other capacitors in that area. If you're not an expert in soldering, I suggest you take the main board to a qualified electronic technician, and let him do it. But you better put the board in an anti-static bag before you take it anywhere! Hope this helps!
