Hello
Your TVs power supply regulator section has got some trouble with it, that is why power indicator doesn't light up. You have purchased it only fourteen days back, surely there will be warranty for it. Do not open the TV. The company will give no concession if the set is opened. Send it to the authorised service center and get it repaired. Some power supply faults may fatal, and may have to spend more. Since your TV is a new model, spare part availability in the open market may be difficult. Send it to them and let them do the work. OK.

My K series JVC TV suddenly went into "On Timer" mode after years of no problems. TV turns off before I get a chance to select "Menu". Don't even know how I turned this feature...


Hello
As your tV doesn't give you a chance to enter into its Menu option, you can't check with its reset function. The only way to reset it is, to unplug it from the wall power socket, and left it idle for at least three hours. Do this and check. if it also doesn't help, you ave to contact the authorised service center for JVC at your town. The main system control and its memeory section will have the trouble. This is ofcourse not a user repairable one. OK.

My LG tv Supreme 21" turns off suddenly while watching. We tried to put the plug many times properly but then the same problem occurs while watching after 15-20 mins. It suddenly turns off. I request you...


The power supply may be loose or needs to be replaced. Further testing should be done to determine. It may have a bad capacitor.

Also if you have a sleep mode on your tv, check to make sure it is not set on in the menu

14 MONTH OLD TOSHIBA TURNS OFF BY ITSELF


I repair a lot of these and a average tv lasts like 3 years . It is not like the old days. I suspect the lamp or fans or therm protector.

I would call a local tv shop see what they charge for estimate it might be worth his estimate to find out what it is.

Changing Remote Control Code

This Remote is capable of transmitting two control codes; one set
to respond to A code control signals and another set to respond to
B code control signals. This Remote control is preset to send A
code signals because your VCR is initially set to respond to A code
signals. You can easily modify your VCR and the Remote to
respond to B code signals. When using two JVC VCRs, set two
VCRs and their Remotes to different codes, so that you can
operate these VCRs separately.

A
Set remote control code for Remote

A
Press and hold A/B.
B
Press the Number key .2..
C
Press OK, and release A/B.

panel.

Our tv will not turn on


Our AKAI was just 14 months old. A few days ago, it died also. Blank screen, no sound, but the timer light will flash on a couple of times when you try to power it up. It even sounds like it wants to turn on. I paid a tech to come to my house $65 and it turns out to be the power supply $385. I checked other chat boards and many people are having this same problem with their AKAI 42" (PT4298HD) televsion. A real piece of junk this model! Sorry for the bad news!
