I purchased a JVC LT52X579 March 30/09. The TV would phase out by itself and then restart by itself. Some times it would remain on and could be cut off only by unplugging it from my sudge protection...


Hi,
Please unplug TV from wall socket for couple of minutes, replug back in and turn ON.
If still does not power up, try it in another wall socket.
Also check standby/ power light flashing or its solid at TV.
If standby light is flashing or its not lit then TV got power supply problem and requires qualified TV tech. I hope TV is still under warranty so ask for warranty cover to store.
Thanks.

My tv model is 43pp8421. when i turn it on, it has a clicking sound and no picture and sound


hello i hope i can help you. may i please ask you. is the clicking sound like a burr?? or it just wont start? if you have a multimeter check the fuse check to see if a break on the mains cable if ok? if ok open tv up and do a voltage check to see if the tv is receiving power? please check the speaker.S? also check the switch. if power is going in but no power on the other side of switch the switch is faulty also check the volume control.

Pioneer Pro-118 won't turn on


Take off back cover. The problem power board is to the right of the board where the power plug feeds into the TV. There is a large white fuse right bend the power plug. With a meter it read ok; about 8 inches deeper into the TV on that board was the resister next to two fuses. My 4 amp 125 volt fuse did not read on my meter. After replacing, it worked fine. Check all three fuses while you're in there.

No Turn On


Check all the fuse devices--most are soldered-in pico fuses in the power supply circuitry. They range in value from 2 amp to 5 amp or more.They are usually a light brownish color.

Let me know what you find....T.

Follow up on "no power to my tv"


Let me give an idea ...after the fuse you have the bridge rectifiers and it can be all in one package or 4 individual diodes after that you have a big filter capacitor and then a power transistor called the switch mode regulator,this are major parts that can make the fuse blow up right away as soon as you plug the set in wall but these parts work along with about 30 other minor parts.If the fuse blew up at plug in it can be one of these but if it blew at turn on from the power botton it can go farther down the power supply,is hard to tell how much is damage and how much it will cost.Get an estimate and then decide.Good luck
