SUBJECT : CHASSIS ICC17 EVOLUTION

If you cannot get the spare part list of a given model number you have first to identify the variant of the chassis because some of the ICC17 chassis has been produced under several variants with the same model number.

1) CHASSIS VARIANT IDENTIFICATIONa) TV serial number starting with "A" or "B" (Fig.1) :

Refer to the last digit of the chassis code printed on the bar code label at the back of the chassis frame. (Fig.2)

First digit of the serial number

Digit indicating chassis typeA or 0 : Variant 1B or 2 : Variant 2C or 3 : Variant 3

b) TV serial number starting with "Z" :Check on the chassis whether the following schematic position, BX80 and BP02 or BP10 are printed or not on the printed circuit board.

Example : Reference commercial : 32WS24E32WS24E1 corresponding to Variant 132WS24E2 corresponding to Variant 232WS24E3 corresponding to Variant 3

Chassis concerned : ICC17

Problem observed :At switch "ON", the TV's standby power supply does not work.

Cause :The reverse voltage of the diodes used in positions DP16/17/18/19 (1N4001) is too low especially when the mains voltage is at highest.

Solution implemented :Change the diodes used in positions DP16/17/18/19 with higher reverse breakdown voltage (400V)type number 1N4004, Part No. 44009009.

Finished products / Chassis concerned : ICC17 28 Inches 16/9 with metal mask(With tube W66EJU023X15)

Symptom/ Problem observed :In the am.models, tube have been changed at the end of 1999 to use tubes with metal maskinstead of invar.As consequence, the products is more sensitive to doming effect, especially with high drive,as met in case of digital transmission.

Cause :Too high peak white with digital transmission in case of metal mask.

Solution :The peak white has be be reduced from 390 to 300 nits what was done on concerned modelssince February 2000.For products having the problem in the field and produced before February 2000, reduce by 12steps the peak white in field service mode.
