Socks asked:


A friend gave me a broken Philips 37PF7320A/37 LCD HDTV and I’m confident I can fix it once I diagnose the problem. When you power on the TV it switches back off after a few moments and the red LED on the front blinks in an error code. This is most often diagnosed as a problem with the power supply board, however it can also be a problem with the standby audio board or the backlight inverter. So if someone can tell me what all of the error codes are - what blinking pattern indicates what error - I’d be really happy.

The error code I have is one long followed by four short, which I have read indicates the standby audio board. However, I’d like an official listing of all the error codes - and possibly a link to a service manual pdf - so that I can be 100% confident before I start spending money to repair it.
Several responses on Fixya.com suggest the error code is the standby audio board (they call it an error 14) ie http://www.fixya.com/support/t1738135-philips_lcd

I’ve found downloadable service manuals from numerous sites, however none of them I consider reputable and they charge an arm and a leg - on top of the cost of replacing whichever board is bad. I’ve tried calling Philips myself with no luck and I’ve spoken to a couple TV repairmen who all say that Philips won’t even give them the light of day if the TV isn’t under warranty - and if it is, they want you to send it in to them.

I have an opportunity to get a decent deal on an audio board on ebay. If I don’t get any new information, I’ll have go go ahead and try it.

As a note - the board on ebay is from a 37PF7320A/37b while my TV is a 37PF7320A/37 (no b). I don’t expect this will make much of a difference, but if anyone knows that it does, let me know.
