Question about Philips 42PF7421D 32 in. LCD HDTV

2 Answers

Our 50" Philips Plasma wide has a red light that flashes also.

We replaced the panel board on the far right but the red light still flashes 7 times. No swollen areas and all parts were checked by an electrician that knows about computer panels and does that work for a living. Mystery still not solved. Any suggestions for what we could try next?

Normally that sounds like a power supply failure

even if the caps look ok check the secondary side of supply rails for ripple or voltage outside of specs.

this is a common problem on these units the caps are (as far as i can remember) are 3300 10v , 100 16v , 1000 35v 330 16v

the other problems i have had with these sets is the resistors that drive the relays going high in value.

Red light flashes


This is a well known and very common problem with all Philips plasma tvs 42 and 50 inch. The problem is they used under rated capacitors in the power supply. If you have electronics experience or a friend that is, remove the cover and look in the back for malformed or leaking capcitors. Replace them and see if that takes care of the problem. The caps only cost $2 or $3 each, so the cost to try this is pretty reasonable although you might have an added cost of buying beer for your electronics friend. If this does not fix your problem you are down to replacing boards that can be purchased around $300 ea.
I have found my set will come on "finally" after I get the back of the set warmed up and the bad caps finally charge up. Hope this is useful.
