Question about Televison & Video
1. Try this - hold the menu button down for 10 seconds. TV should power up; you
will have to turn off front panel buttons on menu.
2. You can also try plugging in the TV through the USB on its panel to a computer or USB charger, and it may work. However, this is only a temporary solution.
3. Powering down the set or putting it in standby may have allowed the power supply to cool. Weak capacitors often go out of spec when they cool, thus preventing a section of the power supply from firing up properly again. There is a simple trick...just warm the back of the TV with a hair dryer for 5-7 mins after you have unplugged the TV. Look for the little areas of holes in the back panel of TV. Use these as your guide at where to use the hairdryer, but don't hold the dryer too close (say 5-6inches away). (Make sure the dryer is on High heat). If the TV doesn't turn on after you have heated it up (like it tries to come on but then turns off) you need to unplug the TV again, this resets it. And repeat those steps till it works. Resetting the TV after it fails to turn on is the key. Also, just leave the TV on. Don't turn in off. Since it is LCD, it doesn't take much power...only a few bucks extra a month for your utility bill.
4. A circuit board may crack about some of the larger components mounted on it. You can inspect the PCB's for fractures, and then repair them. It may also be poor soldering that has failed. I would be checking for these things first.
5. If you want to go in for a long term solution, you can easily replace the whole power board or just change the faulty capacitors. You will have to open the back panel and take a look. You can make out which are faulty, because their caps will be swollen on top. Here's a sample pic (not same model):
Check the specifications of the faulty capacitors, and get the replacements from your local electronics shop. If you are comfortable with this, you can use a pair of needle nose pliers to G-E-N-T-L-Y pull out the defunct capacitors. Once that is done, solder in the new capacitors carefully. If are unsure how to do this, try to get a friend who knows how to do this kinda stuff do it for you, or get a qualified technician. Warning: If you do not have a background in electronics repair, or are inexperienced, get a qualified technician to do it for you.
REMEMBER there are very dangerous voltages inside a TV that can KILL. Be sure to work SAFE when dealing with electricity. DISCONNECT THE POWER BEFORE YOU DO ANYTHING.
Hope that helps!

I purchased mine about 5 months ago. Ive been researching and playing around with the remote. This will help you on the way. With the set off, press "Mute", 1, 8, 2 then turn the tv on. This will bring up the main settings, dont change any values on any page, unless you write the origonal values down first, because the total reset doesnt return everything to a "factory" preset. Scroll down to reset and press the enter key. I havent come across any owners or service manuals, and support is slim to none. I wrote a review for the same model on a wal-mart site I believe, and it explains adjustments in more detail. If you want to try to figure out the buttons for yourself, while the tv is on, press "Mute 1, 8, 3" this is another set of adjustments for finer detail. If you change an adjustment here and your not sure, just press the exit button. To save your adjustments in the convergence mode, press and hold the enter button, it should flash a few times and center itself on the screen. If you make a mistake in this mode, the total reset I mentioned first should get you back on track. If you find anything out or have a question, feel free to write me at Silverado1st@aol.com This is a nice TV, wonder why they stopped making them.

Something like this Id have someone who knows there way around electronics, a qualified tech or someone you trust really well :-) Does the crackling affect the TV picture at all ? My first guess would be dust and or dampness on the audio components. Sometimes this can conduct electricity across small pc chips and reak all sorts of havoc. I had an old Tomas electric organ once, and it actually caught fire because two speaker wires were rubbing together and eventually wore thru the insulation and shorted out, but it was also making alot of crackling and static noises. Try raising and lowering the volume low to high and high to low and see if the crackling noises gets worse. Some audio amplifiers put out quite a bit of power, so I wouldnt trust leaving the TV on without a fire extinguisher handy.
