Make | Model Ch. | Symptom | Problem Solution | Solution | By: |
---|---|---|---|---|---|
Philips | L6 Series | Vertical lines are not straight when picture is very bright or has white text content | Replace 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 down | Small pin hole in line output transformer type FSA36012M | ||
Philips | VR723 LUCY | Power supply LSM-45 would not start up after power failure | Cooling 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 failure | Replaced 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 driver | Check R504 270k, feed to switching transistor. Goes high or o/c | ||
Panasonic | ALPHA 2W | Squeal at switch on then goes dead, channel indicator ok | Check 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 quickly | Replace 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 it | The capstan motor was faulty. Fitted new motor | ||
Salora | L | Dead | DN15 s/c 8v line | ||
Seleco | 26SA37NL | White line in middle screen, several spikes | Check 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 1.6V | The 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 heated | This was found to be due to a faulty micro | ||
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 ! | ||
Loewe opta | Profile E3000 | White vertical line only displayed on tube | Check for dry joint or burnt track on Horizontal Yoke PCB socket or main board | ||
Panasonic | 21LIT | Dead set, only red LED is on | Replace IC AN5606k | ||
Philips | L6.2 | Picture is horizontally narrowed and deformed | Capacitor C2913 390nF, 250V on the deflector PCB had lost capacity | ||
Goldstar | CF28A54L PC58A | Lignes horizontaux aut de l'immage après remplacer | IC - TDA8350Q, Condo 470uF, 25V | ||
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 63 | The 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 defective | Change the value of C2260 to 4n7F, replace 7270 with transistor BD825 | ||
Philips | 28ML8805-16B FL1.6AA | Ticking noise and line in picture | Transistor 7381 BC848C defective when hot |
