Try the below info.,
SUBJECT: Coil getting hot (L505)
DATE: 09/10/2002 MODEL(S): KV32FS13
Symptom: * Partial wiggly in some pictures areas.
* Possible bad linearity.
* L505 is getting hot.
Cause: T504's core orientation has been modified from suffix -11 to -21 due
to the part construction
productivity improvement. As result of this modification this part's
radiated magnetic field also change
affecting L505 performance as well, saturating L505 and affecting linearity.
Solution: If the customer complaints about these symptoms please apply the
following change:
- First check on [A] Board which type of T504 is using (suffix -11 or -21)
If T504 having a suffix -21, replace it with suffix -11,
Transformer T504 Part number: 1-429-188-11
- Check the color of the coil L505, If it is black color, mounted it in
reverse polarity as shown in
picture. (Part polarity mark and PCB mark must be opposite)
- If coil is blue, please replace with black type, part # 1-406-976-11
