Most major manufacturers supply manuals online so if you were to log on to the manufacturer's web site, you may be pleasantly surprised as usually, if available, one is able to download, by model number, Customer Instruction Manuals, Dealer Network for spare part supplies as required.

The information is normally free of charge.

I hope this helps.

You have defective power supply board, Are you OK to strip it down and inspect the board? You will either have to replace the board or have it replaced/repaired professionally.
I hope I have been of help

this mean a dead short in power supply, i would guess bad rectifier or diodes, zener. start near the plug in where power goes in.

check main first, see if any lights are on or blinking also look in back and see if lights flashing. this means something if so, if dead set with no lights maybe main fuse.

Hi,

Click the link http://www.ebay.com or http://www.shopjimmy.com.
Hope you can find the picture and price of each part.
Have a nice day.

Go into your menu under the audio section or features and turn off the SAP.

It may have dying power supply due to such thing as bad caps with domed tops, or bad main board.
You should inspect these boards: power supply, Z-sustain, Y-sustain for nay sign of over heating, bad caps, etc.

This sounds like a problem with your TCON BOARD.

If the board itself is bad and needs to be replaced, the part itself will cost between $50 - $100 and will require a couple of hours labour to replace.

It is possible that it's just a bad connection between the TCON board and its ribbon connectors in which case only the few hours of labour will be required to fix it. The copper contacts at the end of the ribbon connectors may just need to be gently cleaned with a pencil eraser to remove the oxidation and then reseated in the little flip up connectors.

If you are comfortable working safely with electronincs then you can save yourself some money by completing the troubleshooting / labour yourself.

You should be able to find a cheap replacement TCON board on ebay if it's required once you get the part number off the circuit board, or you could probably order the part from a local repair shop.

Otherwise you will have to bring the set in to the shop and have them repair it. Total cost including labour should be around $150.

Good luck. Let us know how it goes.

Hello
Normally Plasma 42" TV uses 240V 6Amps fuses. But if the main fuse should blow up there must be any reson for that. Without retifying it, if you put an other fuse in place, it also will go out in no time as you switch on the set. So make sure that there is no short in the main power regulator section before replacing the fuse. If you are not sure about it, please don't make things worse. OK.

Most time if the caps don't look like they are bulged or out of place then probably they are not bad, and caps are soldered in place. Are there any lights in from or in back on?

man1657,

My experience with this problem has been that you have bad electrolytic capacitors in the power supply. The power supply board is located where the AC cord terminates. Electrolytic capacitors look like small cans and they do have a polarity. Open up the set and look at the board. Look for units which are bulging capacitors. Replace them and the unit should be fine.

If you do not find any bulging capacitors just replace all of them. The do not cost much and could be replaced for $20.00 USD.

Parts are available at http://www.mcmelectronics.com or http://www.digikey.com.

If you do not feel up to replacing the capacitors you could replace the entire board. Go to http://www.encompass.com or http://www.shopjimmy.com for replacements.

Thanks for using FixYa and for the great rating. Please consider a testimonial. Thank you.

This is an indication that you have a problem on the power supply section or on the load because of the following reasons :

1. Over Voltage - the regulator might be cycling on over voltage due to lack of load.

2. Over Current Protection - excessive load or faulty power supply cycling will

trigger the over current protection circuit.

3. Leaky Capacitor - a dried up main filter capacitor or other filter capacitor in the low voltage power supply that is producing an out-of-regulation condition. A bad filter capacitor on the output of a series regulator may result in excessive voltage and the unit will not power up unless isolated.

4. A problem with the microcontroller, relay or its driver, or standby power supply.

This is not DIY and quite technical so I

if it puffed out yes

sounds like a burn-in but are you saying that you can view another picture but no clear because the previous picture is still there. A burn-in is a tv being left on a fixed object like a picture and left there so long this is what you see when you change channels the image burned on the screen, is this what you have?

So the lines goes up and down or is it across from side to side, if it's side to side then it's your terminal power board.

It is on the rear of the set near the sockets.
