Why power light is blinking
These blinks (flashes) are fault indication. By the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside the TV. Count the blinks occur at one time switch ON, carefully. Do it once again, and make sure about the number of blinks. If the flashes are continious, non-stop, the main system control IC should be suspected. If you wish to get more details, check the site linked here. It has blinking codes detail to many brand TVs.

We have a Maxent MX-42X3, it has flickering
This problem is caused by a faulty powersupply/standby board. I have seen this happen way too often on plasmas for the power supply is the most hard working part in a plasma. A component level repair might be possible but it depends on your prior experience in electronics. If you have never worked on a tv before I strongly suggest that you seek professional assistance to get it fixed as it holds dangerous amounts of voltages for several days after its turned off and unplugged from the power supply. As my guru always says "Your life and limb is worth much more than this". You can use our repair directory to search for techs in your area.

Maxent MX42X3 42" plasma Monitor..
Are you sure that its the main A/Vboard coz it sounds like the main power supply issue to me. Anyways the mainboard is the large board usually located at the center of the tv. If you can remove the back cover of the tv and get me a high res picture of the tv I can mark the board for you.
I have a Maxent 42 inch plasma.When you turn it
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!
