    I have the same problem, with aMaxent TV bought in 2003 at Costco.

    I think its a problem related to my set top cable box. So when I get a chance I'll see about trading it out for a new one. It almost looks like a tracking problem. I have been told to get an HDMI cable to connect to devices. Then I could use the HDMI mode instead of Component 1, or whatever I'm using now.

    I have the same problem. The TV flickers for anywhere between 30 seconds to 2 minutes, and then the problem is completely resolved and the TV functions perfectly. Any solution advice would be welcomed!

    It gets worse.  Mine blinks for hours and seems to never go away.  It especially acts up when wathcing something with vivid colors (sports).  I have not been able to locate a solution.

    purchased mine in 05 and a month ago it began flickering wildly after power up. It is getting progressively worse and now it will flicker intermittently all the time!

Picture take 3-4 minutes before it comes on

The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

i had the similar problem. i'm not a tech but like to take stuff apart to find the problem. on my tv i took the back completely off. do not touch the boards. if you follow the power supply from the plug up two boards i found a small white adjustment screw. it was just up and to the right slightly from the plug. with a small screw driver i turned it slightly to the right and the flickering and delayed picture went away. couldn't tell you why it worked but it did. hope this helps, saved us $800 to buy a new tv.

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.

Tv won't stay on

You need to replace one STK393-110 and 2 or more 5amp pico fuses. Very common problem.

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!

If it flickers on start up it will only get worse. Mine got were it took over 3 hours to settle down, and never would stop flickering with DVD'S. Solution for mine: Replace bad capaciator on input circuit board, I found it by using a heat gun to speed up coming on process, Cost me 62 cents to replace the capaciator my self.

Maxent 42 inch TV Keys locked and Remote will not work

See if you can reset the electronics to factory defaults. Also check with the mfg about this. If nothing works you have one sick puppy on your hands.

Try this - turn set on then pull the power plug. Then push and hold the power button to on position for a few minutes.
Release button and plug back in Turn on and see what happens.
