Funai ciwp4206 plasma TV

This TV worked normally...was shut off for the night....next morning it would not power on. The red power light is on. Pressing the power button turns it green for about 3 seconds then goes back to sleep mode, with no picture of course. Power supply makes some quiet squeaks before going back to sleep. Is this a common falure and if so, where do I look??? Does anybody have the service manual for it? I've repaired hundreds of CRT based TVs and monitors...this would be my first plasma but that would make little difference if this is a power supply issue. Many thanks

Oh, and before you tell me to take it in for warranty work...The claim was made and I am being issued a refund for the set. And they have no interest in picking up this dead set so I might as well attempt repair.

Plasma and LCD TV sets are service with board replacement. After board replacement, the proper service information and set-up to do necessary calibrations may be reaquired. Troubleshooting at the component level is very time consuming and complex.

In the lower end models, the manufactures generaly replace the complete TV set rather than take the high cost of servicing.

As for your Plasma set, the best you can do is check the power supply, and see if there are any markings to be able to verify its voltage outputs. You can look around for any visual problems such as visible cold solders or a loose connection.

In the end, you will probably end up with a lot of spare parts for another set like it. If the other set has to be serviced, you will hope it does not have the same fault as the original if you want to swap boards.

It might be the power supply . I have worked on several plasma sets . If one of the circuit boards has a shorted part on it it does that same thing with the light .

This is what i'm thinking too but I wanted to hear form someone who had some experience with this. When you say circuit boards, do you mean the power supply itself or one of the panel driver boards. What puzzles me is this malfunction occured while the set was turned off. Or, I suppose during the instant it was turned off or on. from what I can see, there are 5 switch mode power supplies....i'll just have to go through and verify each one is working. Thanks!
