Question about Flat Panel Televisions
The remote suddenly quit working. The problem with this is that there is no way to change the aspect ratio. Here's what I've tried so far.
1. Changed the batteries
2. Took the remote int the Best Buy geek squad. They tested the remote and said that it was "putting out".
3. The monitor responds to a cable TV universal remote (except no way to change aspect ratio).
4. Unplugged the TV for 30 minutes...no help.
This sounds like the color processor IC is not working properly. If this is the case you will have to have this checked by a qualified technician.

You can find a replacement Capacitor at any local Radio Shack. Just ask them for a 50 Watt Capacitor and they will give you a box of 2 for like $1.45
0.047µF 50V Hi-Q Ceramic Disc Capacitor Pk/2
Link to Item
If the above link does not work, add this to your browser:
You will see the blown capacitor once you open up the back of the unit. It is over to the top left side of the unit.
Here is a link for some basic soldering instructions for circut boards.
Hope this helps out. Good Luck. Let me know if you need any additional assistance.

These sets are manufactured by Funai, in my opinion total junk, yet they command a $1,500 price tag. I cannot find parts available for this hunk of **** anywhere so if this tip helps you fix this set and get it out of your hair, God Bless You! Model number is followed by an M to read: 6842PF M Found no VSUS on connector CN2502 of the SMPS. VSUS was shorted to adjacent GND pin by 120 Ohms. Small high voltage blue capacitor C2250 (Between Two very big electrolytics and right next VSUS diode D2250 (TO-220 package) on aluminum heatsink) shorted, burned. I have two of these sets in the shop at the same time, both of them have the very same problem, appears to be common and parts seem to be NLA for this unit. Replace C2250, 1,500 pF @ 1Kv. Usually marked as 152K on small high voltage capacitors in junk units. This is not a common value part so if you have to, make one by parallelling a .001 uF cap (102) with a 470 pF cap (471) to get a suitable 1,470 pF capacitor at 1 Kv. Adjust VSUS with VR2250 on SMPS board to read 175 VDC to GND and you are done. You're welcome. ~Ohmster

I have an LG LCD TV with the same problem.
The solution is to go to
And select HOME rather than STORE on initial setup.
Mine was set to store as it was a display model.
That means that whatever picture setting you make they will reset after 10 minutes.

Before taking this to a local repair person, I suggest you check with your cable provider. See if they are having trouble with their HD transmission and then have them test your lines. Out here in Arizona with have constant problems with HD due to heat, rodents and poor installations. Your DVR only recorded the problems that were on your set. If these prove fruitless then take the TV to a reputable repair person.

This is the best solution for your problem as a 40 year experience with wires etc. Go to the source of your cable signal connector . Open it and clean the terminals with emery paper , sand the end of the cable shiny clean from corrosion , get a new barrel connectors with gold terminals if possible lengthen the ends of the cable , insert and tighten good, use thick rg-16 or rg 40 cable with good insulation ends crimped professionally with a crimpier or buy ready made , not from dollar store. Get a gold plated professional splitter if you need one or two , it will cost about 15 or more each . Make the cable runs as short as possible, using the thick good cables. If needed get a signal magnifier. From radio shack or the source etc. Connect them good and tight . Ground the splitters . Problem solved , you will get crystal clear channel 2 to 7 including 3 and 4 . Isolate the TV cable from other cables and power wires. Vitally
