Question about JVC AV-32950 TV

No power and won't turn on

The TV will will not turn on with either the remote or front panel. AC power is getting to the power supply and I checked the fuse. The fuse is good. I'm not sure where or what to check on the power supply for proper operation. Is it cheaper to get a whole new main board or fix the individual component?

    I just had the same problem. When I cracked open the backside and
    looked on the panel where the volume, channel, menu, and power on
    buttons are, I noticed that the power button was disconnected from the
    board. It was just a matter of soldering it back to the board and it
    powered up fine from that point on.

If you know how to use the multimeter is to get a service manual. Try http://www.servicemanuals.net Then troubleshoot the power supply and the sweep supplys. In most cases if you had to replace a complete board,unless you get it from an exchange company that repairs boards such as http://www.ptscorp.com, then it exceeds the cost of a new set. Good Luck

Tv won't turn on

Hello
Chech whether AC power get into the power supply regulator section. Just open your tV, and check it. There is a fuse [ glass cartridge type] on the power supply section. Check whether it has blown up or not. If blown up, make sure that there is some shorted components at the power supply section check it.

I have a 1 year old Sanyo Vizon HDTV and was watching a show when it suddenly just shut off and would not go back on again. No storms or any other power surges and it is hooked up to a real surge...

Hello
If there is no power indicator LED lights up when the set is sitched ON, the power regulator section inside your TV is faulty. There is a fuse [glass cartridge type]; on the power regulator board. If this fuse blows OFF the set won't switvh ON of the front power light won't light up. Check this fuse first. You can locate it at its power switching regulator board inside, where the AC power goes straight to it after a filternig circuit. If the fuse is blown out, replace ti with same rating. It ratings will be marked either on its edge rims of on its body by colour code lines. Replace the the fuse; if it has blown out, and switch ON the TV. if the replaced fuse also gets failed, do not put any fuse after, the power supply section has some short with it. It is best to replace the power supply board as a card absis; rather than making "surgery" to it. Some components in it will be very difficult to get too. You can buy a new power board from /Vizio Authorised Service Center at your town. OK.

My vizio e420vl turned itself off and won't turn back on. When i plug it in the vizio logo lights up amber but it won't do anything else.

There are at least two power supplies in any set with remote capabilities; one is on any time the set is plugged into AC and is supplying that indicator and the receiving circuit of the remote, otherwise it wouldn't turn on under normal conditions. The second power supply produces the needed service voltages used when the set is in use. This second supply is a common failure in many sets and it is generally traceable to poor design and the use of low-quality components of a certain type. Vizio may have a repair or exchange program through their service center. I would guess the cost will be between $50-$150 and you might remove the back panel of the set and look for a smaller board with larger-than-average parts on it and is related to the AC cord coming in. It should be fairly easy to remove and replace as these are often outsourced and just plugged into the rest of the set with dissimilar plugs making it simple to install and reinstall.

Could the front contol panel be bad if my T.V. dont turn on

More likely no power to set; either no AC from plug outlet, or internal fuse in power supply.

I have a daewoo pdh42L40 monitor and it does not turn on. The main power switch in the back works, but the little green light on the front does not light up so I can use my remote to turn on.

1. the infrared receiver may be defective and may need replacement.
This will require service from a qualified tech to replace.
2. or you may have a dead remote. check the batteries also in the remote.
