Question about HP LC3040N 30 in. HD-Ready LCD Television

Back Light Failure???

I have the same problem, I have not authorized service person in my area, so HP did send some one to fix it and didn't send the right parts. Its been escalated until after "the holidays" being Canadian I asked what holidays??? Presidents day, not "its a holiday in the US" on Monday... what an arrogant attitude to display, when he has my file in front of him, no help-just attitude. will post after management calls me... I think this may be a system wide premature failure on this part.

I had the same problem. Based on other resutls of a Google search, I replaced the backlight inverter board. That fixed the problem. I got my substitute board from

All you need to replace the board is ap hilipps head screw driver and be comfortable taking electronics apart and handling PC boards (you need to take a couple of layers off before you get to the board).

Your unit is displaying a common formatter failure. The good news is this:

Any HP M2727 manufactured before January 1, 2010 is covered by a service advisory that will get the printer repaired at no charge. You need to contact HP and get a case number or contact an authorized HP service partner. Be insistent, I have seen some service partners who have no idea that this service advisory exists. You can check the date of manufacture by looking at the serial number sticker on the back of the unit.

My Neptune Fav6800aw spin level keeps changing and beeping. All other buttons are non responsive. I had to unplug the machine to quiet it. Once plugged back in it's continued beeping and will not run....

Hello frankga ,

I’m an owner as you and I feel you have a failure with the Control Board in the Console. With a failure such as this a repair person would start by swapping out that component. The Control Board is under warranty for 5yrs. Call Maytag customer service at 1-800-462-9824. The will need your serial number. It’s located on the back right side of the Console as you face it. If it’s still under warranty they will give you contact info for Maytag authorized repair.

I got Maytag to send me a Control Board I told them my neighbor was a repair person and had diagnosed the issue as a Control Board failure. That saved me a $65 service call to have someone come out and tell me what I all ready knew.

If you decide to keep the machine the Control Board part number is 25001217 (ebay used) 25001217 (Sears Parts Direct) 25001217 (Appliance Zone).

The Service Manual for reference. Sears Parts Direct for reference.

The Service Manual on page 73 has the warranty info. Changing out the Control board is a 10 minute job. Most people have problems just getting the console released from the washer top. Follow the SM and you won’t break off any mounting tabs off the console while releasing it.

With a failure of this type I doubt you will be able to get into Service Mode but you can try. If you want to do that and I will help you and maybe we can read the diag error code blocks.

Can you share with us what you feel may have lead up to your failure? Have you had recent electrical storm activity in your area? I recommend a good surge protector at the washer 120VAC source outlet.

Good Luck and let us know if you need additional help or have questions …. Rich

The camera should be covered under a manufacturers warranty, and I would have it looked at by an authorized service technician. You could contact the manufacturer and they should have either a list of authorized service centers in your area, or they should send you a shipping label so you can ship it into an authorized service center. You could also bring it to a Geek Squad® precinct in a Best Buy™ store and they could send it out to an authorized service technician. I hope this helps!

Go Ahead. Use Us.

Usualy when there is a pop or bang, you can be sure that a component physicaly blew up inside!

The fix is to change the associated circuit board(s), or if possible the parts inlvolved. The cause of failure must also be found.

You local TV service man will most likely not be able to properly service this type of set, unless he is properly trained and equiped for this type of service, has access to all the proper test facilities, service manuals, and spare parts.

I would suggest finding out who the authorized service rep is in your area and send them the set for an estimate.
