| Aiwa | C202KER | Field collapse | Fusible link 1500 marked as jumper lead from loptx to reg via D6813 | 14-09-04 |
| Aiwa | SE211K | St/by only | R617 high (replace with 390K 1/4W) - located behind LOPTX.This causes the micro-controller to shut the set down and store this condition in the EEPROM. You can either replace the EEPROM with the correct one from Aiwa (which then requires setting up with a special handset), or use an EEPROM programmer to reset the values. There are two values that require resetting:
$0139 should be $00 ($2F when faulty)
$013C should be $00 ($33 when faulty)

| Apex | Apex 32" | Apex 32" . When I turn it on, I hear a high pitch noise from inside the TV. It starts to chirp in small intervals, then quickly becomes a single continuous tone. No video signal or sound from the speakers. | :D you have a line op stage problem-remove the line op transistor and check it for sc-with the transistor removed load the power supply ht capacitor with a 40w lamp and switch on-check the ht is correct .
if so your power supply is ok,if your line op transistor is faulty a new one may get you working .Check all soldered joints in the line op stage
