Check the TV for dust inside the case by using a clean, dry source of compressed air to blow inside. Also go to all the inputs connected to the TV and tighten them.

SOURCE: 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!

No picture on LG 42LK450-UB TV Red standby light at plug in and blue light on power. Removed cover and no backlights lit Is the board that drives the backlights bad and is board part of the PS board.


Hey Marc,
You question is a little open..... there is more info needed to help narrow down the problem. If it is a backlight issue you should still get sound out of it and you should be able to take a flashlight and shine it on the screen and start to see a picture( note this part takes a little patience and staring, it will be hard to see it but you will if it is there). The backlight driver board is a separate board ( here it is at shopjimmy http://www.shopjimmy.com/auo-19-42t14-001-backlight-inverter.htm ) You could also have a bad main board: example- no back light, no pic, no sound, but it seems to turn on and off. In that example the firmware on the main board became corrupted due to a failing board, so check those places above and feel free to order that backlight board.

LG 42LK450 flat screen.I tried auto tuning but didn't pickup channel 31. I tried manual tuning with no result. The old style TV I had prior to this could pick up channel 31 so it isn't a reception...


If your trying to receive over the air make sure the TV is not set to a Cable mode, if your on Cable your new TV is most likely a ATSC tuner (digital) and the cable company can map channels any way they want. If your old TV had the older style cable tuner, the lineup will be different.
HDTV has level thresholds, if the signal is weak you wont see anything, but the old TV would.
Without knowing much about where or what sort of TV your using, these are my best ideas.

Your probably having what cable guys call a SNR ( signal to noise ) issue. There's no way to know unless you call your cable provider. The SNR should be 32 and above with zero pre/post errors. In case you want to ask the tech what they are.

Volume in the tv is not working, and you turn the tv on or off it comes three to four minutes later. The tv was bought nine months ago, it's an LCD 42 inches MODEL #42MF439B/F7


If it is nine months old the set must still be under warranty, the problem you are describing is an intermittent audio problem and can be difficult to locate. I recommend getting in touch with the people you bought it from and get the satisfaction you deserve.
