-------------------
A production change has been introduced changing IC7260 from TDA3562/N5 to TDA3566/N5. At the same time R3292, R3293 and T7267 are deleted. Receivers concerned are date coded QG12940 and later.
Reason: Alterna | 14-09-04 |
| Philips | CP110 | Initially no picture; low contrast picture after some minutes. | Check to see if T7672 is conducting when the fault is present.
If it is check for ripple on 140 volt HT line. If a ripple is present, check/replace C2670 (4822 124 80494) and 2621 (4822 124 80494). | 14-09-04 |
