Hi, well in my professional opinion, I do NOT think that this is a DIY, venture. This is a pretty serious fault, and requires a fair deal of expertise and equipment to remedy.
My advise is for you to contact either a local or head office of, Philips, and ask them for a referral to an authorised service center. Now make contact with them, and arrange for the unit to be looked at, now ONLY ask for a "Quote" as to the costings of the prospective repair(s). Only do this when the unit is about to be actually being looked at though. Then you can go from there, and make up your mind as to repair or replace?
Error 53.
This error will indicate that the VIPER has started to function (by reading his boot script, if this would have failed, error 5 would blink) but initialization was never completed because of hardware peripheral problems (NAND flash, ...) or software initialization problems.
Possible cause could be that there is no valid software loaded
Try to upgrade to the latest main software version

Hi- tried the software upgrade. It got about 15 seconds into it and then went into protect mode. Now I can't even get the display to come up after power cycling. It probably overwrote part of the firmware but wasn't able to finish. Any suggestions?
Thanks,
Mike
I have a Philips BPU2.3U, 50" plasma(50PF7220A37). It turns on for about 30 seconds and then goes into protection mode, flashing the 53 error code. The manual says Viper, PNX8550 is at fault. I tried upgrading the software, but it goes into protect mode before it is able to finish the update.
