The PIP module is a board that allows you to view two different pictures on your set . Also if your having a convergence problem you might want to suspect an opened fuse that supplys the voltage or possible opened resistors could be causing the problem that your still having . A volt-ohm meter would be helpful in finding your cause . Also be cafeful when checking any electrical device when power is active . Your problem is not your PIP module if your colors are not aligned . Good luck

No spark from new coil


Sounds like the problem lies in the profile Ignition Pickup (PIP) i.e Crank Sensor or in the Ignition Control Module (ICM), once the ICM gets the PIP signal, it starts to switch the Ignition Coil on, Once the Ignition Coil gets this switching signal, it starts to Spark away, I think you are not getting signal from PIP to ICM to get spark. I did a quick search online and if you do need to replace your Ignition Control Module this site looks like it has cheap prices, free shipping and great reviews http://www.buyautoparts.com/ignition-control-module.html

Hey there,i have a 1991 msuatng LX with the 2.3L ho engine running an 8 plug head. it sounds like i may have a misfire of some sort or my timing may be out but im not sure how to tell, could someone give...


Insert each wire on the proper terminal of the ignition coil. Ensure that the coil boots are fully seated and both locking tabs are engaged. The terminals are identified on the ignition coils. Install wires as shown in the illustration. The 2.3L firing order is 1-3-4-2 for both ignition coil assemblies.

Distributorless Ignition System In the distributorless ignition system (DIS), all engine timing and spark distribution is handled electronically with no moving parts. This system has fewer parts that require replacement and provides a more accurately timed spark. During basic operation, the EEC-IV determines the ignition timing required by the engine and a DIS module determines which ignition coil to fire.

Components
The distributorless ignition system (DIS) for the 2.3L twin spark plug engine consists of the following components:
  • Crankshaft timing sensor
  • DIS module
  • Two ignition coil packs
  • Spark angle portion of EEC-IV
Crankshaft Timing Sensor
The crankshaft timing sensor is a dual hall effect magnetic switch, which is actuated by the dual vane cup on the crankshaft pulley hub assembly. This sensor generates two separate signals, PIP (profile ignition pick-up) and CID (cylinder identification). The PIP signal provides base timing and RPM information, while the CID signal is used to synchronize the ignition coils. Initial timing (base timing) is set at 10 degrees BTDC and is not adjustable. Ignition Coil Packs
Two ignition coil packs are used for the 2.3L dual plug engine. The two ignition coil packs are triggered by the DIS module and are timed by the EEC-IV. Each coil pack contains two separate ignition coils for a total of four ignition coils. Each ignition coil fires two spark plugs simultaneously, one spark plug on the compression stroke and one on the exhaust stroke. The spark plug fired on the exhaust stroke uses very little of the ignition coils, stored energy, and the majority of the ignition coils, energy is used by the spark plug on the compression stroke. Since these two spark plugs are connected in series, the firing voltage of one spark plug will be negative with respect to ground, while the other will be positive with respect to ground. Refer to thePowertrain Control/Emissions Diagnosis Manual for additional information on spark plug polarity. DIS Module
The main function of the DIS module is to switch between ignition coils and trigger the coils to spark. The DIS ignition module receives the PIP and CID signals from the crankshaft timing sensor, and the SPOUT (spark out) signal from the EEC-IV module. During normal operation, PIP is passed on to the EEC-IV module and provides base timing and RPM information. The CID signal provides the DIS ignition module with the information required to switch between the coils for cylinders 1 and 4 and the coils for cylinders 2 and 3. The SPOUT signal (from the EEC-IV) contains the optimum spark timing and dwell time information. The dwell time is controlled or varied by varying the duty cycle (duration) of the SPOUT signal. This feature is called CCD (computer controlled dwell). Therefore, with the proper inputs of PIP, CID and SPOUT the DIS ignition module turns the ignition coils on and off in the proper sequence for spark control. CID is also sent to the EEC-IV micro-processor to allow for Bank to Bank fuel control. Failure Mode Effects Management
During some DIS system faults, the Failure Mode Effects Management (FMEM) portion of the DIS ignition module will maintain vehicle operation. If the DIS ignition module does not receive the SPOUT input, it will automatically turn the ignition coils on and off using the PIP signal. However, this will result in fixed spark timing (ten degrees BTDC) and a fixed dwell time (no CCD). If the DIS ignition module does not receive the CID input during engine cranking, random coil synchronization will be attempted by the module. Therefore, several start attempts (cycling the ignition from OFF to START) may be required to start the engine. If the DIS module loses CID input while engine is running, the module will remember the proper firing sequence and continue to fire to maintain engine operation. Dual Plug Inhibit
Dual Plug Inhibit (DPI) is a function of the EEC-IV that is only used when the vehicle is being started at temperatures -7° C (20° F) and below. During engine cranking, the EEC-IV will only fire the spark plugs on the right hand side of the engine. When the engine has started, the EEC-IV will send a signal to the DIS module to start normal dual plug operation. Ignition Diagnostic Monitor
The Ignition Diagnostic Monitor (IDM) is a function of the DIS module. The DIS module sends information on system failures to the EEC-IV which stores the information for diagnostic self test. The IDM signal also is used to drive the vehicle instrument tachometer, and test tachometer for system

Im pretty sure the pip module in my mitsubishi vs-50605 has gone bad is it a real hard fix or is there some way i can bypass


yeah you can use two caps to bypass and pull out the whole pip module. You'll have to find schematics because I cannot find my documentation, if you can't find the schematic, then let me know I can dig some more.. Basically you pull out the pip module and then add in 2 10uf caps to just pump the signal back into the signal board.

heres something i found, not positive its credible but should be safe to try
pull the module out and just push the caps into the connector
if it works, then you can solder in, i usually broke off the old connector to have an easy pop in fix.

oh.. the symptom is usually a black or bad pic, but the pip looks good = bad pip module caps (too many to fix unless you really want pip)

heres your pic

i've seen it work with many diff sized caps, this says to use 4.7uf instead of the 10uf I suggested, either will prob work.

Screen looks like a picture negative, PIP works fine, sound fine


Sony's have dual tuning systems to allow for the separate PIP channel. The common problem on the Sony's is the circuit board and tuning module connections go bad. It is likely that the connections on the board or module were already in the decayed process and moving it just accelerated the issues that were inevitable.

The quick fix is to swap the PIP over to the main picture or to bus the antennae signal to the antennae B terminal thus bypassing the bad tuner module.

The recommended fix action is to have someone with soldering skills to remove the chassis, and locate all the cold and cracked solder joints, especially near the tuning modules. If this does not take care of the problem, the tuning modules will need to be removed for re-soldering on the actual tuner modules.

If none of the above works, then you can always use the audio/video outputs of a cable box or vcr to the a/v jacks of the tv, thus bypassing both tuners in the tv.

Mistubishi vs-45605 pip module


The PIP board is small and square and stands straight up on the main board. It plugs into a socket. It also has a ground wire that has to be unsoldered to remove it from the machine. It is located essentially in the middle of the main board near the rear of the set. Sorry I can't describe it any better. Go to http:\\www.tritronicsinc.com or call 1-800-638-3328 for parts. Thank you!!

Hi i have a 93 Mitsubishi model# ck35402. I was told that the pip had went out. was hoping someone could walk me through on how to remove and reroute


From the bottom of the main board locate IC 2004 between the PIP module and the tuner. Remove the jumper between pins 2 & 6, then jump pins 6 & 7. Next , pull the pip module from its socket and toss it. The symptom for a bad PIP module could be black screen, no picture, blue streaks, wavy or jittering picture.The audio will not be affected. Make sure the symptom fits the cure before you bypass the PIP. Good luck!

Pip module


Your model is the VZ8 that doesnt have the pip board it has an IC for control of the PIP. So your problem has to be in the video or deflection circuits You can get a service manual off this link that I am part owner of if you need one. We also help by giving free support to help with the diagnosis and locating parts. This is a free service when you purchase a manual and we email the manual within minutes of placing your order. Its listed as VS60707 and sells for 10.99 its the full factory service manual.
Heres the link if your interested.

Mitsubishi VS-50707 50 in. Rear Projection...


There is a quick test you can do to determine if the problem is in your PIP module, using two 4.7uf/50v electrolytic capacitors. The PIP module plugs into two connectors on the main board. Remove the PIP module, and on connector VP on the main board (the 11 pin connector), use one cap to jumper from pin 7 to 9 (negative lead on pin 9); and use the other cap to jumper from pin 5 to 11 (negative lead on pin 11). If the PIP module is bad, you will now have video. The PIP module has surface mount capacitors that go bad. Just make sure you solder a small lentgh of wire to the capacitor leads to prevent them from shorting as they cross over each other. Just plug the wires into the socket no need to solder them.
