SOURCE: phone turns on fine but nothing happens pushing buttons except power.

If your phone has a keypad lock option, make sure that the keypad is not locked. Refer to the user manual to know how to unlock the keypad.

It is also possible that the keypad is defective and needs to be replaced.

You most definately have bad capacitors in the power supply. try and get it repaired as soon as possible, not an expensive repair that iv'e seen.

Hi , I have the same problem with my LT-42X688,so i called the service of my extended warranty provider . the TV technician just left and told me the motherboard is the problem. he said its the third one this week he has seen with the same symptoms. he ordered the motherboard and i've got to wait 5 to 7 work days before the part will be in . I will keep you posted when the guy will return.

You have either a power supply board malfunction or a main board gone bad. If the voltages from the power supply board are all present and correct, then the main board is at fault. TV Parts Universal TV Stands DLP Chips ShopJimmy You can get parts here.

Xbox 360 hookup problem


Check the video cable coming out of the xbox, depending on which model xbox it is (arcade, pro, elite etc.) it will most likely have both component cables - green, blue and red or RCA cables - Yellow, red and white. It sounds as if your JVC would only be able to run RCA cables (due to its age) so use the yellow cable for video and white and red (or just white if you only have a yellow and white input) and then make sure the switch located on the cable is switched to "standard" and not "hi definition" hope it helps. aus_joel@hotmail.com -if you have any further problems

JVC LT-32P679 Blinking Power Light, Automatic Shutoff


1. Hold [menu] and [vol-] button on the side of the TV
2. while holding these, press the [power] button on the side of TV (NOT remote)
3. blue light comes ON and stays ON
4. wait 10 seconds then let go of [menu] and [vol-]
5. wait another 30 seconds and some type of picture should appear

I think this is right. I got it from the JVC call centers guys so sorry if I missed or messed up a step.
