Chassis is completely dead


Hi,

Here are some basic steps that will help you fixing the problem.

I'm assuming that your unit is dead set without an standby LED light and your outlet is live.1.Power cord - check the cord it might be opened (no continuity).This is due to frequent bending,pulling. 2. Power switch - check for dry joints, open contact. 3.Check the internal fuse- sometimes the fuse fail because of the power surge, replacing with new one will cure the problem, If this is the case I would advice you to use surge protector/AVR (Automatic Voltage Regulator). However if the fuse blew again this is an indication that you have a shorted parts in the power supply, you may visit the linkhttp://www.fixya.com/support/r8053361-fuse_keeps_blowing for more info. If no reaction and still the unit didn't power up then you have an open parts on the power supply.

4.If you see that the fuse is intact , don't attempt to touch anything because there some fatalcomponents stored electricity enough to hurt you with a simple mistake only. I would advice you to look for a professional to troubleshoot the power supply. If you want to repair it yourself make sure that you have necessary tools and test instrument. First check bad solder joints(re-solder all cold solder), leaky electrolytic capacitor(sometimes it has bulged at the top but not all, you better have a capacitor checker), open/shorted regulator transistor/IC(mounted in heat sink), open fusible resistor (caused by shorted regulator Transistor/IC), shorted zener diode.

Also check if your unit is under warranty before opening the back panel, it will void the warranty. Avail it because the manufacturer of your unit will fix it for free or a little charge only.

Hope I helped you.

Have a nice day!

We had a power outage. TV and video both now dead. Changes fuses in plugs, still dead. Could the fuses in the appliances be blown ?


HELLO

Power outages can damage electronic items!

It is certain that the fuses in each of the units power supplies will be blown but I would recommend that you get both in for servicing as sometimes changing the fuses INSIDE and trying them again CAN cause more damage - and more cost to repair.

Better to be safe than sorry! (:-)

Panasonic #ct32hc43g; no power when power button pushed(yes its' plugged in and the plug works fine with other electic items )


There are many causes for this set to have no power, if you get no red light at all a common fault is the 6.3 amp main fuse blowing in this set. It is because the timing unit for the degaussing coil has changed over time and is staying on just a little to long causing the fuse to blow. A technician will put a 7 amp fuse in as a replacement, Do not use a fuse of any higher value or you will have a fire hazard. If the 7 amp fuse blows then you either have another power related issue or the timming unit has gone way out of tolarance and need changed.

If you have no experience inside of a tv, and don't understand the hazards of electrical shock even with the tv unplugged i would not attempt to open the set up and do this yourself.
A service call from a technician could run around $100.00.

T.V. Has nopower


Try a power drain:
1. Unplug the product's power cable so the device is not grounded to the house. 2. Press and HOLD the product's own power button for 1 minute to drain the capacitors. 3. Plug the product back into a wall outlet and try to turn it on.
Note: This procedure works with battery operated devices as well so remove the batteries and hold down it's power button.  Electricity can remain in capacitors and on circuit boards enough to prevent normal functionality. By clearing the residue electricity, your product will have a fresh start and many times this will resolve a buggy or non-responsive device that appears to be dead.
If the TV still won't come on, and there is no indication of electricity getting through, the problem will be with the TV's power supply or it's cable.

TV DEAD


On some models the reset is unplugging for a minute or two and plugging back up. Otherwise you have a blown fuse where the power goes in. If you decide to replace the fuse do no go over 5 amps. If the replacement fuse blows there is a short in the set and needs a repairman.
