This is a common problem on these plasma TV's. The problemresides in the high voltage boards known as the X and Y Sustainboards.. You can purchase them here for a very reasonable price:
http://www.discount-merchant.com/Y-SUSTAIN-FOR-42-PLASMA-TV-PN-6871QYH036A-p/sku9510.htm

The above link is to a Y-SUS board. The X-Sus board is often the 2nd cause of failure and can be found here:
http://www.discount-merchant.com/X-SUSTAIN-6871QZH041B-6870QZE017D-6871QZH052D-p/sku9509.htm

Totest which board is failing, you need to check voltage input to theYSUS board first... Input should be 120V from Power supply, outputshould be above 250V.. Do this test with XSUS disconnected. IF 250+Vexists, then XSUS is damaged. If not, then the YSUS is the faulty part.

Hello,
Your power supply board is 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.

Sony FWD-42PV1 -


I diagnosed the same problem on my FWD-42pv1 as a problem on the Y-SUS board. The fuse on that board was blown, and the board itself was bad (replacing the fuse was not enough to fix it). The symptoms were exactly the same - the LED cycling red/green, and then finally stuck at red.

With a new Y-SUS board, the TV has been working fine for a couple months.
