| Make | Model Ch. | Symptom | Problem Solution | Solution | By: |
|---|---|---|---|---|---|
| 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 | ||
| Sony | KVA2542 | Fault not limited to this model. Turning itself to standby, mostly when warm. Flashing error code on LED's. | Dry joint on IC TDA8179 under metal shield. May need replacing with STV9379. May also need to alter picture geometry settings HSIZE, HPOS, VSIZE, VPOS in service menu | ||
| Ferguson | TX92 | Dead, No LED, 2.5Amp fuse O.K. Some voltages present at BP02 ON/OFF switch connection. 160v at terminal D of TP16. 26v, 200v, 13v lines all zero | Replace TP16 P6NA60FI and diode DP17 BZX55C15 | ||
| Panasonic | NV-HD101 | No picture on e-e, I.F output ok | This was due to switching chip IC3901 M51292FP on the scart panel | ||
| Ferguson | TX92 | Field fold-over / flyback lines visible at top of screen | Capacitor CF30 47uF, 50v | ||
| Tatung | C Series | No remote control op | Microprocessor MN15151 | ||
| Samsung | CB5020 P58SC | Tuning not stopping | Replace R116 120Kohms this was open circuit | ||
| Sharp | DV3760H | Dead, led flashing red/green at first, then going to red standby | Replace C604 1000uF, 16v elec. cap. It is in the decoupling circuit for the 5 volt supply | ||
| Ferguson | ICC9 | Ew distortion | Check / replace CL42 4.7uF, 160v, don`t forget to use 105 Celsius type replacement | ||
| Rca | CTC166/167 | Audio, no video | Change Capacitors C4501 and C4502, in the vertical section | ||
| Grundig | 8214 | Poor linearity / Vertical deflection problems | Check +D voltage on pin 12 of the vertical deflection module. If this voltage is less then 35V or has ripple replace C628 3300uF, 50V, also check fuse SI627 T3,15A. Sometimes this fuse has resistance causing a voltage drop across it | ||
| Sony | FE-1 | Set shuts down shortly after start up with standby led flashing 2, 4 or 5 times | Check / replace chip resistors R543 47Kohms and R541, R573 and R575 all 100Kohms | ||
| Panasonic | TC1400T | Int loss of signals | Check R545 for dry joints | ||
| Akura | CX11 | Appears to be no line drive but if scoped the drive is at very high frequency | Suspect C308 3.3nF high stability type | ||
| Sony | FE-1 | Changes channel or volume adjusts by itself | Check S900/1/2 on pcb H1, alternatively this could be due to failure of IC005 CD4052BCM-FL63 on pcb A | ||
| Panasonic | NVF70 | Bad picture, may be stripy with blue spots | Change C22 in the power supply 680uF, 10V. I used a 1000uF, it works great | ||
| 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 | ||
| Hitachi | C2558TN G8Q | The H.T wouldn't vary at all, even though it was actually at the correct level 157V | ZD941 BZV10 was found to be o/c. It's a 6.5V zener diode and not as i had assumed by the numbering on it a 10V. ZD941 and the H.T pot VR941 are located next to the optocoupler | ||
| Sony | FE-1 | No power no standby power supply op | IC609 TOP209 was faulty, also checked C640 47uF, 25v, D631 MTZJ-12B, D628 P6KE200, D629 UF4005PKG23 and R627 4.7ohms, 5%, 0.25w as a precaution | ||
| Panasonic | NV-G40 | Picture noisy on all channels | Transistor Q4 D1330 o/c |
