Make	Model	Symptom	Problem	Solution
PHILIPS	GR2.2AA	Dead, no line oscilation, power supply and line output stage are ok	Check / replace c2549 390 or 470nf / 400v and c2545 1n5 or 1n2, 2000v
PHILIPS	GR2.2AA	Does not work after lot has been changed	Check / change d6561 also change the tda2579b if there are any sync problems
PHILIPS	GR1AX	Sometimes does not start up from cold, but starts well from power off or standby after a few minutes	After checking all psu components and consulting many colleagues, casually the tip of my iron touched the body of t2628 bf423 and the set started. after more then 20 attempts, i realised that this transistor became intermittent when cold
PHILIPS	VARIOUS	Sound but no picture	Have found on some philips	S if they are older then 15 years that a 2.7r resistor close to the ht transformer goes open, resulting in sound but no picture
PHILIPS	28PW6005 A10	Changes to ext 1 when watching tv ok with video input	Ic7064 defective, replace it. philips best nr= 311125054501. price = 48 euro, after replacement the smart settings have been set to 255 read the instruction note for this software!! code number instruction note = 996500013923
PHILIPS	CP110	Vertical ripples on horizontals	Replaced c2633 100µf, 25v
PHILIPS	CP110	Image appeared after a 5-20 minutes, sound was choppy when changed by the remote	Replaced c2690 100µf, 50v with a 100µf, 63v type, this is located on the small overvolt board in the power supply area
PHILIPS	GR2	Sound but no picture	Check the lot cable for short circuit
PHILIPS	21PT166B/00 AA5 AB	No drive to lop transistor	Middle sections checked ok. carefully scoping the tda8361's hor. output showed gnd level to be at +0.8v not enough to drive next stage. change the tda8361
PHILIPS	GR2.2AA	Protection circuit operating intermittently	Diode 6592 was found to have leakage causing voltage to protection circuit to be too high, should be 23 - 28mv
PHILIPS	ANUBIS A	Low contrast	C2448 47uf, 200v open circuit
PHILIPS	21PT5505/05 L9.1E	The fault with this tv was a snowy picture no channels tuned in also the permanent 33v supply on pin 9 of the tuner was low at only 1.6v	The first thing i tried was a resistance check between pin 9 and ground. the reading was only 120Ω. there's a surface mounted cap right next to pin 9 of the tuner. this was found to be leaky, it's value is 47nf. also resistor 3442 3.9k was o/c
PHILIPS	14PT1352/58 L6.1AA	Sound goes off and no remote control functions when heated	This was found to be due to a faulty micro
PHILIPS	CTN-BB	Dead. f1500 o/c, mosfet s/c	Mosfet t7525 shorts, due to smoother cap c2505 goes low capacity. ic7514 tda4605 must also be replaced
PHILIPS	25PT532A/05 GR2.2	Power supply dead, blowing fuse	Fault was transistor but124f 7625 short circuit, replaced transistor and also changed ic cnr50 7614 and tda8385 7600 this solved the problem
PHILIPS	25PT512A-05 GR2.2	Dead set ht 140v ok	Replace standby thermistor thy6670
PHILIPS	L9.2E	Fuse 1572 blown	Disconnect pin 44 on ic7600, if the fuse stops blowing suspect processor ic7600. it is really expensive, at least in sweden !
PHILIPS	GR1AX GR1AX	Will not start up from cold	Check if 95v line increases to over 100v when tr7628 bf423 is chilled. if so, replace d6629 bzx79-c12 and re-check 95v/re-adjust r3625. may also be worthwhile replacing tr7628 and c2629 as a precaution!!
PHILIPS	GR2.4AA	Power supply protection enabled	Replaced zener diode 6561 bzx79c68
PHILIPS	VR110	Power supply tripping	Damaged print at one of the pins on primary side of transformer
