SOURCE: Samsung TV flickering
This is an unusual failure of a non obvious part in the power supply putting noise into the circuitry of the TV.
you either need a competant tech to work on it or if you are good at connecting up cabling just swap out all the guts.

SOURCE: RCA TV flickering problem
Help! I have an RCA 40 inch HDTV (Model# D40W20). I've had it since 2005. Recently, the picture will flicker when I turn it on, but will stop flickering after a few minutes. My brother has the 52 inch model and his tv did the same thing before it broke down completely. Does anyone know what the problem could be?

This sounds like a repair issue. I do not believe there is any in-home troubleshooting that you can try that will fix that particular issue. I would call Samsung tech support to see what their opinion of the problem is. Their number is 800-726-7864.
I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.
Please post a comment if you need additional assistance so that I can help you further.

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!
