How to check and repair
1. The function of FIL_OCP is to protect tube
focal spots.
2. Check voltage between Test point (TP402)
and Heat sink (U406)
(Normal: 3.6VDC ±0.1V)
3. If the voltage is not O.K, adjust VR402 to
fix the correct voltage.
4. It is strongly recommended that VR402
is strictly prohibited from uneducated
persons. (Keeping factory setting is very
important)
