Hi,

Based on the way you describe this issue,I would say that the problem is the power supply board.I do not think it needs replacement,probably just some defective capacitors are causing all the trouble. Please open the back cover and take a visual look at the power board.You might see one or more bulged top capacitors(not perfectly flat like the others). If you see any please replace them,this will restore the normal operation. The explanation for this is,that these defective capacitors cannot filter right the power supply 's output voltages,causing main board to malfunction. You can replace the power supply board instead of repairing it,but this will increase considerably the cost of repair.

Other than this, it could be Y Sustain Board or Z Sustain Board.You need to Check all the Boards before replacing it.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

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.

We have a Maxent MX-42X3, it has flickering througout the whole picture.


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.

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.

TV picture flickers


If your DVD player is separate from your tv, you might have a loose cable plug or connection. Depending on the type of flicker you have, a vertical circuit loose connection would cause this. If you could connect it to a cable or antenna it might tell you where the problem is located. A faulty circuit in the DVD might cause this too. Stargazer
