This is an indication that you have a short on the power supply section.

It can't be fixed by replacing the fuse alone. I've suspected that you have a short on the following parts :

1.Power Cord - even very low of chances but still to be check.This is due to frequent bending and pulling.

2.Rectifier diode

3.Main filter electrolytic capacitor

4.Voltage regulator I.C.

This is the common parts that might be shorted and made the fuse blew. #2-4 is quite technical and need an expert to do the job so I

Inspect the power supply board, Z-SUSTAIN board, Y-sustain board for blown fuses, caps, IC, Transistors.

If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on: Basic LCD monitor and TV troubleshooting guide: http://www.fixya.com/support/r5093881-lcd_flat_panel_tv_troubleshooting_guide http://www.fixya.com/support/r6150077-basic_lcd_monitors_troubleshooting http://www.fixya.com/support/r7406380-tv_training_manuals Failed TV and Monitors: http://s807.photobucket.com/albums/yy352/budm Learn about bad caps: http://en.wikipedia.org/wiki/Capacitor_plague Parts: www.shopjimmy.com Capacitors kit: http://lcdalternatives.auctivacommerce.com/Default.aspx he can make you a set of caps. Or www.digikey.com, just make sure to use caps with low ESR, 105c, high ripple current and long life rating such as PANASONIC FM or FC series. Please post back what you find. Please leave rating if it helps.

If you were to log on to the manufacturer's web site, I think you may be pleasantly surprised as usually one is able to download, by model number, Customer Instruction Manuals, list of Dealers for spare part supplies and Driver downloads (if applicable) as required.

The information is normally free of charge.

I hope this helps.

it is going in shutdown mode due to a defective electronic component, it could also be the power supply check for swollen capacitors (inside the TV) they are small alluminium cans with a plastic shrink with numbers and make printed on them, the tops should be FLAT not rounded (about to burst)

Good luck!

Checking the power supply board,that the board,where the power a/c cord plug into it.Could be dying to be dead capacitors parts.Check the power supply board carefully,look for capacitors parts are bulging or puffing up on it tops.U have all the tools and know basic eclectronic also can do basic soldering.Replaced all these dying to be dead capacitors parts,will solved this problems.Or try website like Ebay.com,to buy a whole refurbish power supply board for the replacement.

Re-Seat the ribbon display connectors on the bad side which connect to the y-upper and lower boards. Try that first.

You may have blown a ribbon cable out of the connector with the air. The speakers could also have been disconnected this way. If the remote doesn't work then it may be a the subboard for the sensor. If both remote and buttons don't work then it would be a larger section.

Unless you used a few hundred psi you would have to work hard to actually hurt something. Unfortunetly you can do just enough with low pressure to be rather annoying. Basically if this is the cables and not just a couple of things happening at the same time to fix them you need to crack the tv case and reinsert the cables into the connectors. Not hard to do but takes a bit of work to get at all of them.

Check ur tv owner manual for that phone numbers or try the Gateway.com webite itself.Or tries websites like Amazon.com,Ebay.com to buy base stand used or new.

Do you have your television connected to a cable or satellite?

If so, please ensure the device is powered on and plugged in. If you have pets, sometimes they can knock them loose.. Also make sure you are on the correct input to view the services.

Same goes for a dvd player, surround sound, etc. Its just the input that would change.

The only thing you can use is the stand that came with the Television. I'm not sure if there is a way to buy aftermarket stands that are universal or not. But generally it's recommended to use the original stand or purchase from manufacturer. Check this link out also, in case you may be interested.

Hi,

This is an internal fault as you must have observed. There could be many causes for the same. It could be a problem with power supply board. Other than this, it could be Y and Z sustain boards. However, it needs a proper inspection and testing of these components. If you have electronics repair experience, know how to use multimeter and soldering iron, could read schematics - i would be glad to provide you with a link to purchase service manual ( if available ) and could guide you to fix the problem.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Have you tried connecting in another outlet possible the connection is the problem

check the switches there is a loose connection somewhere, If you have a transfomer check it also

Most likely your speaking of dead pixels. No real solution other than if it is still under warranty they could replace the panel.

Sorry pal.

I'll sell you mine for 150?

Over loaded lines means not physical overload but rather overload of voltage. Usually happens when a component such as a voltage regulator IC fails.Did you test the board with a multimeter?If not take the back cover of , turn on the set and notify me at what location(marking on the board and IC numbers of any ICs near by) you hear the click as it means that the relay at that point is clicking off there by forcing the tv into standby. Make sure that you don't touch anything when the set is on.

Yes,it's normal, a plasma uses a lot of power (over 300W) so it generates a lot of heat - especially the screen.Remember, plasma is an overheated gas so a large screen contains a very large amount of a very hot gas.

Hi


Thanks for using FixYa. A plasma TV is a very hard working device. It is working harder than any TV that has been built before, and as a result it produces a lot of heat. 75% of technical problems in plasma TV's are caused by overheating problems. You’ll need to check the power supply board first for any swollen/bulged capacitors. As power supply board is the hardest working board in a plasma TV, it develops voltage to supply all components, high current + high voltage. All this is only recommended if you have electrical expertise & know how to solder/re-solder components as these units contain high voltages even when switched off. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks

The power board has definitely failed. Sounds like a short that could be causing the cracklin sound.

I have ordered from this place before with fast shipping and no problems.
Hope that helps.
