2. SYMPTOM/REASON :
The FBT is damaged due to arcing as shown in the attached picture. If the FBT is produced by
Termal, it must be changed with an Eldor FBT.
Note: The pin positions (on PCB) of Termal and Eldor brand FBT?s are different. Thus, 3 metal
eyelets should be removed and 5 eyelets should be added.
Please apply the following procedure to replace Termal FBT with Eldor FBT:
- Desolder the pins of Termal FBT and remove it.
- Remove the metal eyelets in position E17, E19 and E20 by cutting heads on the
component side of PCB (It is not necessary to remove E18)
Not: It is needed to prevent a possible arcing from ferrite of Eldor FBT to the eyelets of old FBT.
- Place metal eyelets (part code : 013114 ) to positions E12, E13, E14, E15 and E16.
- Fasten eyelets by applying pressure to the solder side with a (+) type screwdriver and turn it.
-Â Solder new Eldor FBT on the positions E12, E13, ... (see the component-side layout below).
? If CPT brand is 28? Video Color (W66EJU023X015), then
Heater resistor R529 has to be replaced from 1R to 1.5R to
decrease the Heater voltage (for other CPT brands and
screen sizes, the R529 should not be replaced).
?? The part number of FBT is actually 058838(28?) and
058238(32?) in SPPL. So, if you order with those
part number, Beko will deliver Eldor FBT automatically.
