Was fitting a chip to my dmax and engine light came on how can I get it off


follow this steps and fix it. God bless you

When you turn the ignition ON before starting the car, the "Check engine" light is supposed to come on indicating that the engine computer (also could be called ECM, PCM, or ECU) is powered on. If the "Check engine" light does not come with the ignition ON, it's possible that there is no power coming to the engine computer (e.g., due to a broken wire, faulty main relay, burnt fuse, etc.) or that there is a problem with the engine computer itself.

If you have a voltage meter there are some things you can check.
Unplug the unit and remove the back cover of the set. Then Plug the unit back in.
You will need to tape down the lamp safety switch in order to do these tests.
Here are all the failures that would give you a lamp error and what to check.
Cause 1. Unit powers on and works properly for a while then shuts off with a red lamp led(lamp error). Suspect bad lamp and replace.
Cause 2. Unit does not power up correctly and you have red lamp led(lamp error). Check the lamp enable line at connector J14 on the back of the light engine. If pin 6 does not switch to 5 volts after turn on, but your 12 and 5 volt supplies are good, then suspect a defective light engine.
Cuse 3. At power on the lamp turns on and off 3 times and then the unit shuts down with a red lamp led(lamp error). You have a defective light engine.
Cause 4. Unit does not turn on correctly and you have a red lamp led(lamp error). Check for 12 volts at connector J9 pin 4 on the light engine. If voltage is missing check for an open fuse F9A09 on the power supply board. If it is open, then you need to replace the fuse and you still have a defective light engine.
Cause 5. Lamp enable line at connector J14 pin 6 on the light engine does go to 5 volts at turn on, but does not drop back to 0 volts after 5 seconds, but your 12 and 5 volts supplies are good then you have a defective light engine.
Cuase 6. Check for 5 volts at connector J9 pins 1 and 2 on the light engine. If low or missing check Capacitors C9A37 and C9A38. Values are 3300MF/10V. Replace capacitors if defective.

This is all I have and I wish you luck.

DLP RCA HDTV is displaying bars from top to bottom of screen, with green tint. Is this the light engine going bad?


Hi

Thanks for using FixYa. This issue can happen due to a faulty light engine or due to a a faulty DLP Lamp. However, it can be an issue with the video driver card of your Card. I'll suggest to use a DVD player and check if the tint is still there. If the tint disappears then its an issue with the video driver card.
However, if it doesn't correct the issue its either a DLP Lamp or a faulty light engine.
Note-- Please make sure to turn off and unplug the TV for at least 1 hour (this will drain off current from all components especially capacitors) before you perform any repairs. Also note that the TV consists of very high voltages even when it is in OFF condition.

Before performing any repairs i'll suggest you to try and reset the TV by unplugging it for 8-10 hours.

Please do accept the solution if the issue is resolved or else revert for further assistance.

Thanks

Mitsubishi 62 inch microdisplay hdtv w/screen w/zy


I have a list of problems common to this series here:

Cause #1
1. (Lamp may light and go out) suspect bad lamp part # 915P020010 2. Check for
12-volts DC at J-9 connector pin 4 on the Engine Driver PCB, if missing check
for an open F9A09 on the Power PCB, if it is open replace F9A09 part #
283P127060 and the Light Engine part # 939P977010 3. (Lamp may light and go out)
Check for 5-volts DC at J-9 connector pin 1 and 2 on the Engine Driver PCB if
low or missing check C9A37 and C9A38 both 3300 UFD 10 V part # 181P732040 on the
Power PCB (part # 930B921002) 4. At power on the lamp turns on and off three
times and then the unit shuts down with a red lamp LED (lamp error). Replace the
Light Engine part # 939P977010 5. Lamp enable line at J14 pin 6 does not switch
to 5 volts after turn on, 12 and 5 volt supplies are good. Suspect the Light
Engine part # 939P977010 6. Lamp enable line at connector J14 pin 6 on the
Engine Driver PCB switches to 5 volts after turn on and does go to 0-volts (low)
after 5 seconds, 12 and 5 volt supplies are good. Suspect the Lamp Power PCB
(ballast) part # 939P978010 7. Lamp enable line at connector J14 pin 6 on the
Engine Driver PCB switches to 5 volts after turn on but does not go back to 0-
volts (low) after 5 seconds, 12 and 5 volt supplies are good. Suspect the Light
Engine part # 939P977010

I would start with #3, checking the 5 volt line and replacing the listed capacitors if needed.
Please be sure to rate this solution. Thanks!
