Checked all the resistor there for change value and also the capacitor for short or leaky can caused the short.

Hope it may hel you;

Getting trouble code 106. What is solution for correcting this problem. Thank you. 2005 crossfire.


Chrysler codes,. only.

p0106,

on newer Chysler, cars they have many codes with 106, leaving out the prefix is bad idea.

Like U0102

or C0106?

P0106 is MAP performance failure. (that dont mean replace it)

the puter has no IDEA what is wrong, only that tests failed.

here are the conditions.

When Monitored and Set Condition



  • When Monitored: Engine running for at least 30 seconds and no fault in the throttle valve actuator.


  • Set Condition: Low limit: The Manifold Absolute Pressure (MAP) Sensor reading is below a calculated value when the throttle valve angle is greater than 80F for approximately 5 seconds. High limit: The MAP Sensor reading is greater than a calculated value that is determined by engine speed and throttle valve angle for approximately 5 seconds.




now in gringo or bar stool.

1: the puter brain saw you go near wide open throttle and the

map sensor (vacuum sensor) do not show new zero vacuum.

even a clogged air filter could do this, causing a false high vacuum







POSSIBLE CAUSES




MANIFOLD ABSOLUTE PRESSURE SENSOR SIGNAL CIRCUIT OPEN




MANIFOLD ABSOLUTE PRESSURE SENSOR SIGNAL CIRCUIT SHORT TO GROUND




MANIFOLD ABSOLUTE PRESSURE SENSOR SIGNAL CIRCUIT SHORT TO VOLTAGE




5-VOLT SUPPLY CIRCUIT OPEN




5-VOLT SUPPLY CIRCUIT SHORT TO GROUND




5-VOLT SUPPLY CIRCUIT SHORT TO VOLTAGE




5-VOLT SUPPLY CIRCUIT SHORT TO SENSOR GROUND CIRCUIT




MANIFOLD ABSOLUTE PRESSURE SENSOR SIGNAL CIRCUIT SHORT TO SENSOR GROUND CIRCUIT




MANIFOLD ABSOLUTE PRESSURE SENSOR SIGNAL CIRCUIT SHORT TO 5-VOLT SUPPLY CIRCUIT




SENSOR GROUND CIRCUIT OPEN




ENGINE OIL SENSOR




MANIFOLD ABSOLUTE PRESSURE SENSOR




POWERTRAIN CONTROL MODULE






then the FSM goes to step by step tests. to find above reasons.

omitted. (too long )



the word low is ambiguous in all FSM.

it can mean, low plenum pressure,

or low vacuum (opposite)

and low voltage, its a pain in the xxx to find this fact out.

the map outputs high voltage for low vacuum (same as high absolute pressure)



the fsm tests are inane.

we check the voltage out of the map

at keyon

running

and wide open throttle for 1 second. just gun it and watch.

here is what it does.

left side is wide open throttle, idle is 20 inchs. key on is, WOT.

so, what is that

4.5v is keyon

start engine, get about 1.5v

the gun engine, then drop throttel to zero throttle fast

the causes,. huge vacuum about 24 inches, or 1v or less

this is a working MAP. if those tests pass.

the test (OBD2 monitor) fails for about not getting near 4vdc from MAP output pin, DOES THIS HELP?

When we try to turn on the tv (toshiba model 32A43) it makes the sound of turning on then off and the screen stays black and a red light by the power button keeps binking


You're either losing high voltage or power supply is not producing the horizontal drive signal, Check for 130v on the collector of the horizontal output transistor, if you're missing your voltage, you have a power supply problem. If voltage is too high you have something open in the power supply such as a low value resistor. If its low, something is shorted in power supply, possibly voltage regulator ic.

Lambda ews600-18 voltage goes down.


there is a short circuit protection and overoad protection to smps so o/p capacitor may short or secondary diode may short .so check voltage at primary when switched off after 33seconds whether switching process is going or not for that check dc volt at i/p capacitor then check volt at collector of transistor if metr shows 1digit then switching is going if not then meter shows full dc volt check component near about that

We have a Toshiba 52 inch TV, model # TP50G50, manafactor date on it is July 1997. The picture & the sound went out all at once, do you know if it's a fuse or something more serious? It's hard to haul...


It is a power supply fault. The power supply is a switched mode power supply and supplies 5 volts for the difital logic and high voltages for the high voltage parts of the tv relating to the screen display components. When the high voltage part of the circuit breaks or goes short circuit then the power supply shuts that part down leaving the low voltage rail of 5 volts..hence the standby still working. So... you need to be looking at the power supply board where the mains goes in but be aware of the mains voltages in this area if you arent experienced in electrics. The board will still hold 240v if the power supply has an open circuit load

Sony 2167 No power on


I have not worked on your particular model. But, I have serviced many TV sets over the years. My answer will ge generic.

Check all the capacitors in the horizontal output stage and power supply areas for high ESR. All the caps that are out of spec must be changed.

The high voltage multiplier & flyback can also cause the fault you are having.

You have to consider that the DC voltages are not the only important spec that has to be met. There are also many power drive signals that work with reactive devices. If there is any defect in the critical areas there will be failures.

Directv h20 receiver has low volyage to the lnb.


Check inside the receiver for a defective LM317 IC or a TIP42C transistor, but before that you should check for proper voltage from the power supply to that IC.
LM317/TIP42C control the switching of voltages that power up the LNB, you should be getting 14 volts for vertical channels and 18 volts for horizontal.
Good Luck.

When the horizontal output (2SC4927) is shorted it means one of 2 things is wrong - the horizontal drive transformer has cracked solder joints or the flyback transformer is shorted inside. If the solder joints on the horizontal drive transformer (the small grey transformer connected to the base of the horizontal output transistor) are cracked then the set will play for a little while and then the parts you just replaced will again be destroyed. ALWAYS resolder the driver transformer when replacing the parts you mentioned! When I replace the parts you mention and I do not see any obvious cracks on the driver transformer then I unsolder the B+ pin of the flyback (labeled 135, for 135 volts) and put a 60 to 100 watt lightbulb (drop-light) in series with the flyback. This means that the 135 volts B+ goes through the lightbulb and then into the flyback, so the lightbulb acts as a current limiter to protect the horizontal output. When you turn the set on the bulb should glow no more than about half bright and you should hear the high voltage come up, but you should not see a picture. If you turn the set on and the bulb glows as bright as if it was plugged into the wall then you can bet that flyback is shorted and must be replaced.

Horizontal White Line


Sounds like something is getting hot causing voltage loss or drive pulse loss to the vertical IC. Maybe you have a bad solder joint. Try tapping the circuit board around the vertical section. A capacitor could be heating and opening up. Stargazer Also you might try using circuit cooler spray and make the problem show up.

T.V. wont turn on


The voltage might be low because is being loaded down,open the collector of the output transistor and measure the voltage again,if it goes up to 130 or the voltage is suppose to have you might be looking at a bad output transformer(flyback)there are other parts that can cause the loaded down voltage,the yoke can be one and capacitors in the deflection circuit,check to see if one of this caps is overheated (bubble)or cook,Be carefull if you open the collector when you measure the voltage,If you can try measuring the voltage somewhere else.Lets Us know if you need meore help.

Help on monitor repair


Have you checked the horizontal output transistor for a short or leakage?? most of these sets will not start up unless the horizontal sweep sends the pulse to the power supply and says start me up!! I would look at bthe drive as well on the horiz. curcuit. If theres a pulsating voltage that means its waiting for something to signal it to work or its missing something.. Good luck
