Toshiba | V709B Samsung | Very slow rewind / fast forward | Center Gear assy u/s, cracks and drags on , same will apply to Samsung and some Sony machines etc | ||
Toshiba | 217D98 | Severe field distortion | Check capacitor C317 2.2uF, 50V in linearity feedback circuit | ||
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 | ||
Toshiba | 28W8DB | No frame drive however sound and line drive is present | E/W correction chip TA1240 at front of line/frame was defective, replacing the IC cured the fault | ||
Toshiba | 3798DG C8SS | E/W Pincushion distortion | Replace D461 damper diode ERC20-06 | ||
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 | ||
Toshiba | V730UK | No display, red LED flashing | Replace C1SS35 1000uF, 10V | ||
