I have a JVC 36" tv (model #AV36950), 9 yrs old. While watching the set today, it suddenly made a "popping" sound and shut off, then kept trying to power itself up. The power indicator light kept coming on and off as if someone were pressing the power button, but no picture. I unplugged it and it stopped. When plugged back in it did the same thing. No warning or problems of this sort before. Is this a power pack thing and is it something I can replace or reset the unit? Thanks for your help.

Re: JVC tv shut off and won't come back on
It is a power supply problem. As your set is nine years old all the electrolytic capacitors at the power supply area may be out of range. If you are not familiar with electronic repairs it is bettter to take to service center to check and decide according the cost you will asked.

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.
The problem you describe is not really related to a timer function being set. The unit is in shutdown and the light is blinkng to let you know there is a problem.
There are several possible causes. the most common is a failure in the vertical deflection circuit due to a bad vertical IC and possibly a capacitor, zener diode and resistor.
The menu screen does not function the display. Without the original remote or a universal remote that does not have a display button, try unplugging the television for at least 2 minutes or more and plug the tv back in. This should reset the tv display. If the universal remote has a display button, depress the display button until you get the desired display results. Reference the user guide below for the display button.
The 'pop' may have been an arc of electricity from the flyback coil. The flyback is the device that produces very HIGH VOLTAGES --that can kill so be careful--. It may have just goten old and the material around the flyback broke down and allowed the electricity to arc to a near by source to ground. it happens when CRT sets get old. Typically I expect 7-10 years of a consumer grade CRT.
Other then that any fix for it would have to be performed by a trained technician because voltages can linger in the 'caps' and even the 'tube' itself for years, I once got 'bit' by a set that was left un-plugged for 5 years.
From what you describe, a solder joint has probably cracked loose in a power supply or deflection circuit, which is quite common. Since you do sometimes see a good picture, all of your major components are fine. Repairing cracked solder joints is a very easy procedure and definately worth fixing on a 32 inch TV. The first 2 digits of the model number indicate the size of the TV.
