| Make | Model Ch. | Symptom | Problem Solution | Solution | By: |
|---|---|---|---|---|---|
| Bush | 1473T | Dead set, Blown BU808DF | Replace the BU808DFI and check or replace C602 in the base feed. The drive appears normal, but the set can be slow to start, the BU will overheat & eventually fail again | ||
| Philips | ANUBIS A | Low Contrast | C2448 47uF, 200v open circuit | ||
| Lg | CI29H40 PC8KA | There was a bright white screen with flyback lines on this set. The A1 adjustment had very little effect | I found that IC901 TDA6108JF on the tube base was faulty, pin 7 blue o/p and pin 8 green o/p both read s/c to ground. Note: this chip was probably taken out due to the tube flashing over as in my case | ||
| 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 | ||
| Panasonic | NVHD100 | Dead after storm | Check the STRS6545 regulator chip and the mains fuse | ||
| Bush | 11AK19 11AK19 | Lack of width / no ew control | The east west fet Q603 BUK444-200A was short and R629 2.7ohms fusible was open, replacing both cured the problem. Addition to above: R629 27ohms 110deg tube found open without Q603 or other component failure, problem fixed by replacement R629 | ||
| 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 | ||
| Bush | ONWA | Dead | Fit a power supply kit from SEME RK215 for a safer and reliable repair | ||
| 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 | ||
| Jvc | AV21F1EN | Channel reception lost if tuner socket moved | Dry joints on IC522, IC521 and IC541 located in the big heatsink about middle of the main pcb | ||
| 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 | ||
| Panasonic | TC15M1R | Tries to start, led lights once, and shuts down | Disconnect pin 6 of loptx, set should run with frame collapse. Replace frame IC to effect cure | ||
| Naiko | N2811W PE92 | The display is blue with bad graphics and parameters wrong | The 24C16 IC02 EPROM was faulty as Bush WS6674, Got from CHS for £4 | ||
| Bush | 2059NTX | Dead, stand-by light on | All power supply voltages OK. no drive to line output. IC102 faulty TDA4505E | ||
| Panasonic | NV-HD625 | Loss of colour | Filter BP301 may have poor internal contacts | ||
| Grundig | VS500VPS | All power is oscillating | Select 4934 on remote then 0000 key, should then clear | ||
| Vestel | 11AK19 | Screen blanked out with 4 coloured lines two thirds of the way down from the top of pic. Sound OK | 100 ohm resistor connected to pin 6 of the frame output chip was o/c. The IC is TDA8356. The resistor is R704 and is on top of a small hole in the | ||
| Panasonic | CT-T14R | El diodo en paralelo con condensador electrolitico C810 vuela porque este voltaje esta bien alto cerca a 200 voltios debe ser 138v | Cambiar la R610 de 110k estaba alterada | ||
| Toshiba | V705B V3 CAT 1/2 | Intermittent dead | When pin 11 of IP001 U4614 jumps between 8v and 10v suspect shorted 2SA1020, as the secondary is shorted, leaving the chopper switching between on/off states | ||
| Toshiba | AVM 2505 G3V25050 | Will not come out of standby, no picture | If at power on voltage on pin 37 of the micro drops low then reverts to 5v suspect memory chip ICA07 Toshiba 23319016 |
