NEI | E5 Chassis | Chirping at low brightness with line jitter | R655 330k & 1M across it hi res | 14-09-04 |
NEI | E5 Chassis | Dead - Chopper tr IC651 & control chip IC651 s/c | D653 BA159 s/c use BYT52M as replacement & check tracks for damage | 14-09-04 |
|
NEI | E5 Chassis | Dead - no o/p from psu | Check for R654 820k o/c, C665 o/c, IC651 faulty | 14-09-04 |
NEI | E5 Chassis | HT low - max of 140v | P651 HT preset 2k5 fallen in value | 14-09-04 |
NEI | E5 Chassis | Line freq incorrect | C122 4n7 leaky - pin 40 IC101 | 14-09-04 |
NEI | E5 Chassis | LOPTr goes s/c at sw on | D705 BA157 s/c or crt internal s/c at final anode, C124 2n2 o/c (pin 39 IC101) | 14-09-04 |
NEI | E5 Chassis | No raster - volts across T702 400v instead of 1kv | C709 's' correction cap o/c, if so C710 2µ 350v, R709 10k fusible may have failed | 14-09-04 |
NEI | E5 Chassis | No raster - no/low line drive | Check D701 1N4148 clamp diode, D705 BA157 leaky, line dr trfmr pri winding hi res (should be 4R3) ot IC101 jungle chip | 14-09-04 |
NEI | E5 Chassis | Pic bowed or lack of width | C753 680nF 400v | 14-09-04 |
NEI | E5 Chassis | PSU low O/P - appears to be tripping | D652 BA157, C657 47µ R664 10R o/c. T651 BUZ90AF low gain - if volts across C665 is 260-270v replace it | 14-09-04 |
NEI | E5 Chassis | Servicing the NEI E5 Chassis | See TV mag July 1999 | 14-09-04 |
NEI | E5 Chassis | Squealing noise tho' works ok - T651 hot | D653 s/c - BYT52M | 14-09-04 |
