Sony FE-1
No soundThis may be remedied by entering TT24 in the service mode, if fault persists Q202 2SC2412K could be leaky
Sony FE-1
No remote control operationCheck as necessary D203 MTZJ-5.6B on main pcb, D907 MTZJ-9.1A on pcb H1 or the remote control sensor IC900 SBX1981-51, part no. 8-742-014-11
Panasonic TX28DK2 EURO 4
No surround soundAs Mark said in a fault on the Euro 4 , Replace the TDA2030.

Dead SetCheck DP21, 39V Zener, in the startup circuit
Lg CF-28A50T PC-58A
Flyback lines on picCheck resistor R351 in front of TDA8350Q. It should be 3.6 K. I replaced with 3.8 K and it worked fine. Additionaly check: R708, FR704, FR359, Q351, Q345. If fault persists try replacing the TDA8350Q
Panasonic TX-14/21GV1
No operation, standby led blinkingReplaced C840 47uF, 25v which had gone low in value
Philips 28PW6332/05
Loud bang internally, then completely dead. Plug fuse ok. Set about 4 years oldInternal 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
Vestel 11AK19
Screen blanked out,with 4 coloured lines two thirds of the way down from the top of pic. Sound OKR704 100 ohm resistor connected to pin 6 of the frame output chip was o/c
Goodmans 285NS
Buzz on sound when volume at low levelDry joints on earth pegs of heatsinks of audio and frame output ICs - confirmed by comet service, long time ago!
Bush 28ZKF
TV seems to be dead apart from the front ledsOn main board check Ntype TX BD441 which is clipped to the main heat sink. The clip can come loose causing the TX to overheat and melt its connections to the CB. Remove TX test and if OK solder back on making sure TX has good connection to the heatsink
Toshiba 28WD98B
Stuck in standby, 16 volt line low at approx 8 voltsReplaced C872 220uF, 50v, original had gone low in value
Toshiba 2573
Stuck in standby.Replaced ZP82 o/c And tuner internal short
Akura AP2821-S
DeadReplace RP05 1 meg, 1/4 watt
Grundig T55-640 CUC 6300
Sleep timer box on screen, remote & front buttons not workingChanged the EEPROM IC847 24C04
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 visibleCheck R3438 3R3. In my case this was o/c and a replacement restored normal opperation
Sony KVJ29MN21
Unable to switch on with remote and no LED display at the front of setDue to STBY 5v missing. Checked and found the 5v reg/reset IC002. L78LR05D was s/c, replace the IC to clear the fault
Thomson 24WK25US ICC17
No/Low contrast after EHT flashoverCheck/replace TL02 and TL59 in the beam limiter circuit
Jvc C14E1EK
Tuning drift,worse at high channel no'sDry joints inside tuner unit, connections between edge of pcb and lugs
Ferguson 59K7 ICC5
Severe vertical jitter on picture, horizontal sides of picture raggedReplacing the TDA4950 cured the fault
