I have a Panasonic TH-42PX600U and the RF board displays a red light and the screen says no channel found. Can I change the board myself, does it just snap into place

ten flashes from the light is a problem that needs to be issolated by a tech the 1st board to check is the PA board,and all the boards require authorization from panasonic to replace. that is why a tech must do the repair. if the unit is under warranty they must honor the warranty. extended warranty must honor the agreement you signed or purchased. there are a total of 6 boards that can cause the 10 flashes and can be costly to repair that is why I say when ever buying these types of sets get the extended warranty. these sets are no the sets of old they are not componet level repaired but board level repaired.

Replace the mainboard, it is going to be damaged, there is a chance it could be the powerboard but it is quite remote to take into consideration.

I would guess it's the power unit for the TV itself.

If it's still under guarantee I would have thought you should be able to get it replaced.

Yes the control board would definitely be the offender here. But a word of caution. Oftenj when this board goes 2 other boards are also compromised and not always obvious at the time people think they can just swap the board out.
It went for a reason, not just old age. So it is better and cheaper in the long run to get a professional to check it out.

Also from a safety aspect, this is the High Tension area of the TV. Also be aware that radiation of the X type is in abundance at the rear of the tube. The TV must be grounded when opening ( but my advice is dont!) Let the professional do it

Hello,

All you need to do is to open the back cover of the television to check for burnt transistor , this is always the problem , for you to fix this it require a basic knowledge on electronics,
Your power supply board is not yet dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

I hope this will help out in solving the problem
