Question about Maxent MX-42V1 42 in. Plasma Television
It was doing this while connected to HDMI and once it starts you turned back on and a few minutes later goes back off by itself if I swicth to coax (no HD) stays on, I thought it may be something wrong with all the HDMI connections(I tried all of them same results) so I switch to composite and worked fine for a few months and now it's doing the same thing while connected to composite, does anybody know how to fix this?
Sounds like some loose contact with any of the connectors inside. Contact any service technician. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" or "Magazine" will make surf easy Pull up older posts. Surf the site with patience.

SOURCE: volume control problem
The MX50X1 uses a series of tac switches for ch+/- vol+/- and power. It would be my first suspect. The vol- tac switch may have become thermal or what we in the industry refer to as the windex syndrome. We see this a lot on direct view TVs usually because the switching board is directly below the screen and every time someone cleans the screen with windex an trace amount of the fluid might drip all the way down to the board and invade one or more of the tac switches. This isn't the only reason a tac switch goes bad or becomes thermal sometimes it just simply fails... Tac switches are cheap (less than $2.00) but the labor to put them in is probably one shop hour. Find a good shop and have them do it - - If you're not sure where to find one goto: http://www.nesda.com/locator/state_search.php and start your research from there... Good Luck Bill PS: Impress the shop you call and tell them you think your TV has developed the windex syndrome. They'll probably think you know a lot more than you do about TV repair. :)

We seem to have had the same problem. Green light keeps blinking but will not turn set on or off. I unplugged the set for a few minutes, plugged back in and works fine but will happen from time to time for no reason.

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!
