It should either be secured with screws or plastic clips that need to be pressed in to release the board

Hey guys, my caravan started this morning then shut off and won't start again. Heres what I did so far checked fuel pump fuse good, fuel pump relay good swapped with other. Removed neg battery cab


If you have voltage at the fuse and relay, and at the pump, but no fuel pressure, I would say the pump has died or the tank is empty.
Have you checked for voltage at the pump yet ?

MITSU 65513 BLINKING GREEN LIGHT WONT POWER UP


Good Day, xbossux;
This a very common problem with model. Don't listen to other comments unless the use the correct replacement parts.

SYMPTOM: Power LED does not stop blinking after plug in.

CURE: replace C9B01, C9B02,C9B10, and C9B11 (1000 uFD 16V) on the DM PCB. Replace them with part # 181P734030 (680uFd 16V).

The DM Board (PCB) is located on the very left side of the TV looking from back. Caution on removing Board and note what cables you disconnect to access the Metal Shielded Board.
Good Luck, big IRISH.

Ballast Verification Process
1. Short out door switch (SP001)
2. Apply AC power and wait till DM module boots
3. Press power switch and observe spark gap on ballast
4. If spark gap arcs, suspect Lamp. If color wheel starts but ballast won’t strike
lamp, go to next step.
5. Measure BP252 on AC IN CBA for +300Vdc. If missing check door switch, cable
from AC IN CBA to switch and AC IN PCB. If correct go to next step.
6. Monitor pin 2 of BT251 for Ballast ON command from Light Engine. If present
suspect Ballast. If missing suspect Light Engine. Pin 5 of BT251 starts at 3.3V
after power switch is pressed and drops to .18V when the Light Engine sends the
start command. No change on pin 5 indicates Light Engine is suspect, change
on pin 5 with no ballast start, ballast is suspect.

Note: Lamp may arc but not start. Pin 5 of BT251 is "LAMP LIT" and goes to 1.48V
when lamp is lit. If ballast strikes lamp but lamp won’t stay lit, suspect Lamp.

The capacitors are solderd into the circuit board so you have to melt the solder with a solder Iron to remove the legs of the capacitors from the circuit. Then you have to install the new capacitors in the same pin holes and resolder the legs. Be sure that the negative side of the capacitor goes back in the correct hole like the old one was.

The power supply is what provides all the standbye voltages that get routed to the various other boards. The capacitors have to be unsolderd and the replacements solderd in.
