I'm currently performing some repairs on a control box for a vsat system and through the use of a handheld FLIR unit, we have noticed that the first of 3 LT8610 circuits gets warm. Ambient temperature of the board is 23 degrees Celsius and when the unit is powered up, the LT8610 hovers around 30 degrees Celsius. We have also noticed that the 4.7μH also reaches a similar temperatur. The unit does not power on at all. Is there any kind of fault finding we can perform on this chip to allow us to fix the problem?
