Larry,   I'm having a similar problem with my WD-52525 (blinking light and what not). I took it in to an authorized Mitsubishi  repair shop and was told a bunch of  bad capacitors in the power supply and the format board needing to be replaced and  gave me an estimate of $ 700.00 dollars. I said no thanks and had them return it. I have some component level experience and thought I have nothing to lose. I removed the power supply and noticed that 4 caps had been replaced. I should have powered it up when I received it, but I didn't and now I have it all apart. My question is what about the format board and where is it located?   Any repair info would be greatly appreciated.     My email is [email protected]      Thank you......
