Sounds like The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electro-medical.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
Search the site by type in the "brand name" to your device; in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

My JVC model. my JVC TV LT 42 EM 59 will not come on .I get no blinking blue light no power no nothing I get nothing I've tried to reset it in nothing


With no power it will not reset---if total dead unit you would have to first follow the power cord into the set to the line fuse it goes almost directly to---check the fuse first and examine the power supply board for damage or puffed up filter caps.

Dryer power is on. When I set the cylce and push start nothing happens. Already checked the belt and it is fine.


Have you check go see it you are getting a full 220v to the dryer, assuming it's electric. If there's only one leg of the power the control power would come on, but nothing else would work.

There is a problem inside the set. There is nothing that will lock the set up. I would start with the power supply. Thanks

Been setting in storage a year when all hooked up it starts up just fine then quits and sets there with the timer running but wont wash or spin or nothing wont fill with water


When you mention that it starts up fine. Do you mean that the machine initially takes in water, but then nothing after that. Or does it simply power on, but no water comes into the machine.

If no water comes in initially, then it is most likely your inlet valve.

If water comes in but no motor action, then it could be a raft of things. Disconnect the power source. Open the top hatch and the back panel. Make sure the drive belt has not come off during transport. Also check to see if no wiring connection has come loose. NOTE: Make sure the machine is off and disconnected from the power plug.

If you can't spot anything loose then it is best to get a service technician to diagnose the problem.

Stuck in suspend/sleep/standby... I think...


Take the battery out for a minute and put it back in. Don't plug the AC adapter in. Now turn it on. If it comes on go to 'settings' 'control panel' 'power settings' set everything to 'never' and make sure nothing is checked under the differant tabs. Ray

Won't turn on...


It's possible that the convergence IC's may be bad in this set along with a few resistors. A TV repair shop should be able to fix the set for you.
