Philips L6 Series
Vertical lines are not straight when picture is very bright or has white text contentReplace resistor 3420 in the beam current circuit 12k or 15k replaced with an 18k
Daewoo Video Combi Model: GB14F7T1
Smoke came out of vents, then shut downSmall pin hole in line output transformer type FSA36012M
Philips VR723 LUCY
Power supply LSM-45 would not start up after power failureCooling down of the machine during the power outtage triggered the problem: inside the supply module excessive heat is present that causes components to age rapidly, especially those that are located close to the heatsink. Replaced cap. 2116 100nF, 400V
Philips VR722 LUCY
LSM-45 power supply faulty after power failureReplaced elco 2112 100µF, 385V and capacitor 2116 100nF, 400V. See also my tip about the philips VR-723 Cooling down during power outtage. Cheers
Toshiba Video Combi Model: VTV1402S
Dead, or intermittent start up. No voltage supply to line driverCheck R504 270k, feed to switching transistor. Goes high or o/c
Panasonic ALPHA 2W
Squeal at switch on then goes dead, channel indicator okCheck the l.o.p transistor Q551 for s/c, overvoltage diode D854 for s/c, R564 / R567 fusible for o/c and also check C808 10uF, 63v and IC801 STR54041M and locally for dry joints
Nokia SP71D1 and others Stereo Plus
Tv does not start from stand-by. Indicator led blinks quicklyReplace the two smd condensers in parallel between pin 2 of IC NO62 reset line. Remove all of the red glue below the condensers. These condensers must be replaced by new ones of 47nF and 100nF in parallel. IC NO62 TDA8137 sometimes must be also replaced
Matsui Vid Combi Model: TVR185
Accepts tape then immediately ejects itThe capstan motor was faulty. Fitted new motor

Seleco 26SA37NL
White line in middle screen, several spikesCheck power switch for arcing, also check 1 ohm resistors on switch board for possible dry joints
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 1.6VThe first thing i tried was a resistance check between pin 9 and ground. The reading was only 120 Ohms. 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 heatedThis was found to be due to a faulty micro
Philips L9.2E
Fuse 1572 blownDisconnect pin 44 on IC7600, if the fuse stops blowing suspect processor IC7600. It is really expensive, at least in Sweden !
Loewe opta Profile E3000
White vertical line only displayed on tubeCheck for dry joint or burnt track on Horizontal Yoke PCB socket or main board
Panasonic 21LIT
Dead set, only red LED is onReplace IC AN5606k
Philips L6.2
Picture is horizontally narrowed and deformedCapacitor C2913 390nF, 250V on the deflector PCB had lost capacity

Finlux 71G2 ID:54361330 Stereo Plus
Bottom half of the screen is black. Very distorted picture in top half. Volume weak. The programming menu, and the "Extra" menu, has disappeared. In "Service mode" Mute, M and TV buttons in sequence, all settings are set to the max. value 63The existing IC "SPL 40R01" in location NF10, and the connected EEPROM in location NF80, was replaced with replacement IC "SPL 51R02" and an empty EEPROM. It comes in a kit, which also includes installation instructions and a user manual
Philips 28ML8805-16B FL1.6AA
Power supply faults. BUX85F in micro SOPS defectiveChange the value of C2260 to 4n7F, replace 7270 with transistor BD825
