Philips 42PF5521D Plasma Tv

My Philips 42PF5521D works fine with my Sky HD box I can view HD channels and use my Playstation 3 on it all via HDMI so not sure what all the other posts are on about. The only issue I am having is with the darn PSU so much so that after 4 years I now operate the TV with its back off so I can squirt a burst of freezer spray on one component on the PSU board as it will not start up at room temp, a quick squirt with freezer spray wait a few seconds and switch the mains on and hay presto the Philips TV works fine untill turned off, I have replaced all the capacitors on the PSU myself as I am a repair tech but as of yet not got around to source a replacement chip for the faulty heat sensitive chip an MC34067P. I also had to go in via the factory setup / service menu and adjust the red as everything was too red on Normal, cool and warm, the red was set at 209 where green and blue were 190 in normal mode and I took the red to 190 this solved that issue and now its perfect. It does seem to be a but cheep from the inside, the PDP is fine as are the PDP control boards such as YSUS and ZSUS and CRTL_OUT (as they are Fujitsu boards but the tuner / cpu seem a but cheep although they are working fine still after 5 years so maybe i''m being picky here The PSU does seem to be a rotten egg there are 2 designes used in the 42PF5521D one made by Samsung apart from the crap Samwah caps it seems solid and once caps replaced with decent Panasonic ones the TV will no doubt work forever. The second model PSU used is a Philips own make, this suffers from several issues caused by the control chips and some capacitors located arounfdthem, the PSU is basically 5 PSUs on one board each with its own PWM control chip (very over complicated I could design a simpler one) these PWM chips seem to fail on various locations on various voltage rails, after greif with mine I got a price for a new board £350 if you can find one as they have been discontinued since 2009 ! I have just bought the chip needed to fix mine once and for all so it should be woking as intended again in a few days with the back screwed back on with all 45 screws !!!!! I doubt I would buy a Philips again my 32PW6552 (widescreen CRT TV) failed after 3 years costing £700 new so the modern stuff they make seems pretty poor, I do have an old portable 14 inch CRT TV from the eraly 1980s in my shed and thats still going strong and its 30 years old ! yet a modern set bairly lats 5 years crazy hay ???

I own an audio visual business and as such have a pretty good idea about technology etc. I have to say that Philips need to be lined up against the wall and shot for what they have done in describing this product (and others)! They state fully compatiable with personal computers as you would expect - WRONG - you can connect via the HDMI port using a DVI input but for those of you like me who have VGA it''s a big NO NO. Philips customer services are probably the worst in the world we deal with every other major brand and they are all 10 times better than Philips at least. In a word forget this Plasma better ones are available!
