PHILIPS Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| PHILIPS | 20GR1250/52R GR1-AX | Tv turns on automatically. power supply works well, +5v present but seems that cpu 7700 does not no standby mode, no remote or control on the front of the set | After replacing cpu tmp47c434 and crystal 1770 4.0mhz both control worked intermittently. replacing transistor 7674 bc548 solved the problem | ||
| PHILIPS | 28ST2781 GR2.2 AA | Dead, psu ticking | Flyback cap 11nf, 1600v was burned which caused the bu508af flyback transistor to fail. changed both | ||
| PHILIPS | A10E | F on top right hand of screen then loss of geometry data and int shutdown, unable to restart but when try do so set cuts out | Painter ic failure, a small 100 leg device a joy to change if you have the right gear ! ref ic7064 also updated software on new ic | ||
| PHILIPS | 28PW6332/05 | Loud bang internally, then completely dead. plug fuse ok. set about 4 years old | Internal 4a fuse blown. bang was 330pf cap 2540 across psu mosfet exploding, suspect went s/c. diodes 6513 & 6511 cracked and s/c. replaced c2540. could not get diode 1n5062/byw55 rep, so replaced all 4 diodes with by399. psu mosfet removed and checked,ok. voila | ||
| PHILIPS | 25PT4103 L6.2 | Blank screen no audio. no results from tuner or scart socket. when g2 on lopt is wound up a red line is visible | Check r3438 3r3. in my case this was o/c and a replacement restored normal opperation | ||
| PHILIPS | VR6264 | No video or rf output. 12.3vd.c. rail from 7002 bd678 dead | Fault traced to dead short component located on pcb502 at componet ref no. 2024 philips blue radial capacitor 330uf, 16v. philips part number 4822 124 40849. cap has markings 036k0 t0 on it. replaced and all sprang into life ok | ||
| PHILIPS | 24PW6005 A10E | Intermittent or no sound, mute transistor not switching on, ref 7701. | Possible software problem! replace micro. circuit ref 7064 part no 3111 250 545 11. if thats too expensive then try fitting a 22k resistor collector to base of transistor 7701 in mute circuit! | ||
| PHILIPS PLASMA | 42FD9954 S FM24 | Green dots flashing over the screen in av mode | Change resistor value r3641 from 1k to 100Ω | ||
| PHILIPS | L6.3 | Failure of fusible resistors r3929 and r3930 both 560r | Unfortunately when these blow it is a sure symptom of loptx failure. when replacing these resistors, check the big blue 470nf, 250v capacitor behind them for signs of heat damage and replace if necessary, to avoid a recall with resistors gone again! | ||
| PHILIPS | 20PT3742 | Dead with led blinking 4 times | The vertical output ic. is short circuit | ||
| PHILIPS | 29FL1770 OR 25FL1760 FL1.0 | Lights flashing at the front, if carefully interpreted they point to the primary of the power supply | Replaced 2sb 3795b chopper transistor, heated the heatsink with a hair dryer and it started right up, weird as the transistor was reading fine | ||
| PHILIPS | 29FL1770 OR 25FL1760 FL1 | When selecting a channel it locks in initially but will then go off tune as if the voltage tuning had varied | Replaced the tda i.c. in the tuner i.f. section. tried the capacitors first of course. | ||
| PHILIPS | 29FL1770 OR 25FL1760 FL1 | No pictures or sound | Disconnect the p1 and p2 plugs on the right hand side board. l.o.p.t. side. if the set now starts up then change all sound output ic's | ||
| PHILIPS | 25FL1760 FL1 | Set tries to go to stereo as indicated by the on screen display, but most of the time it is stuck in mono, when in stereo the right channel was hissing | Replace the tda8415 on the stereo decoder board, confirm this buy putting multimeter on pin 7 and 8, they should have a voltage of 3.2 volts | ||
| PHILIPS | 14PV184 | Dead set / blown fuse | Replace d6313, 6314, 6315, 6316 and r3337 2r, 5w | ||
| PHILIPS | 29FL1770 OR 25FL1760 FL1.0 | After replacing the line output transformer, the following sympton was displayed. display flashing standby light and stereo ii | Short s23 and s24 briefly, which will put the set into service mode. option 1 should read 010 this applies only to the 25fl and 29fl. option 2 should be 001 for sets with text and 004 for sets without text | ||
| PHILIPS | 21GR2751 G90B | Stereo set with no sound off air, maximum volume produces low hiss, some sound possible if station is detuned slightly. sound via scart is ok | Replace ic u2829b on audion panel | ||
| PHILIPS | 14PV220 EPSILON 2001 | Dead totally | Smps chopper ic 7310 mc44608 p75. i had no output from pin 5 with start up voltage pin 8 ok at 290v. if start up missing check start up resistor 3335 1k. the only power supply i found for ic 7310 was philips direct, part number 9322-143-51682, cost ~ £10 | ||
| PHILIPS | VR6448 20921 | Mechanism jammed, some posts hard to turn | Grease has turned into cement!! oil most of the moving parts, and move them to ensure oil penetrates | ||
| PHILIPS | 33SL5796/16B FL 1.0 | Snowy picture specially in vhf band. after about 5 minutes, picture snowy in all bands. about 10 minutes after switching on, no picture nor sound, just snow on the screen | Replaced the tuner/if. original code was fq816me which is no longer in production. replacement code is fq916dme |
