I have a Philips 42PF7220A/37 April 2006.Chassis Number BP2.3U TV that does not work.The front LED flashes red seven times and the power supply led flashes green three times.VSCAN voltage drops to zero (or climbs).I unplugged the power feed cable to the y-sustain board and the error codes go away and VSCAN voltage remains at -190VDC.I replaced the y-sustain board and the error codes went away for approximately 30 minutes only to return again.I still did not have a picture for that 30 minutes

- O.K.I was able to solve this problem on my own.I had to replace both Y-Buffer cards (Upper and Lower) along with the Y-Sustain card.
I took a long time for the cards to arrive.Even with the long wait, I am pleased with the results.

- I tried to format the table as good but I goofed.
I googled the OEM part number and found the cards.
I could not find the site where I found the table. It took a lot of searching.

- I googled the part numbers and ended up on a website that allowed me to purchase the buffer cards for around $120.00 each. The Y sustain card was purchased of of e-bay for $80.00 including shipping. I think that I got lucky with the Y sustain card.
It took a lot of searching to find the cards.
Each card had multiple part numbers on them.
LJ41-02759A = LJ92-01200A = Y Sustain LJ41-02760A = LJ92-01202A = Y Buffer Upper LJ41-02761A = LJ92-01203A = Y Buffer Lower
I searched today for the same part numbers and they were priced much higher.
The site was a Vance Baldwin parts store which is where philips must be distributing their replacement parts.

-   I also have the same problem, red light blinks 7 times. Won't power up. Green light blinks 3 times. Help-   hooptydue
Most likely the YSCAN UPPER board and/or YSCAN LOWER Board also gone. Your new YSUS board may damage again if you don't replace the bad YSCAN boards. Try to replace the three boards together and then to verify which boards are bad one by one. Good luck.
