There is a burned capacitor cx3210 and melted thermister thx3415 in Zenith B36A24Z Can dirt cause this problem from overheating or arcing?


When more dust accumulate, and absorbs moisture from the atmosphere, ther is a chance to get arcing. Clean the device by using a vaccum cleaner if possible. Burned degaussing coil cannot be repaired. It should be replaced along with degaussing posistor.

TV wont power on


Device is a thermistor (thermal resistor)
thermistor and a vatistor control the on
time of the degausser Sams Photofacts has the
schematic for the set have to match the suffix041eb6a.jpg
Some public Libraries stock photofact schematics you
may be able to go to al local library and get the part number
or the specs as to whether it is ptc or ntc etc to get a match
or online here

Frige not cooling numbers not lite for fridge but freezer temp numbers 567 are all lite. unplug and plug in and both temp numbers r on 4 but u go back and fridge number is not lite and freezer is on 567


If you unplug it you must wait for at least 15 minutes before restarting the unit. This goes for any refrigerator so the coolant system can equalize and the compressor will restart.

There are 3 components involved with this error code. The defrost thermistor, The defrost thermostat and the main control board. Most likely you have defrost thermistor or themostat that is open and the compressor will NOT start because the power for the comprssor has been interrupted by the automatic defrost cycle and nothing is telling the unit that it has completed the automatic defrost cycle so the unit does not restart. The thermistor and the thermostat would be #1 on troubleshooting list. The thermistor will have varied resistance 10,000 Ohms and under and the thermostat is supposed to be OPEN / have continuity above 60 deg F and closed below 60 Deg F. .

If you need parts information I need your COMPLETE model number (Not Kenmore elite)
Example would be 110.11112222 (not your model number and all numbers willmost likely be different) I think your model number will start with 795.something because this unit was made by LG.

Thanks for choosing FixYa,

Need to know the value for Capacitor CX3211 on the edge of the board. The CX3212 next to it reads HR R 561K 2KV and I wonder if they are the same. THe CX3211 burned and the TV died. I am layed off and...


The value of CX3211 is 1000pF 10% 2000V, ceramic disc.
You can also download the service manual from this website. Make sure to download all the 7 files.
Good Luck.

CRT TV vert section


Hi,

Vertical linearity is more of a DCV bias issue rather than feedback or AC coupling. Hence it would be more apt to suspect resistors rather than capacitors. Of course, it is also possible that the large IC that drives the Vertical output maybe at fault (least likely) but often would have trimpots for adjustment. Most current designs do away with trimpots and rely on self correcting (feedback loop) which is simply a resistor in the 100k range. In certain instances, it could be a thermistor or resistor or diode limiter attached to the yoke itself.

Best would be to use a service manual or at the very least a schematic diagram with voltage readings and compare actual on PCB against schematic.

If you could post back the make & model or preferably the chassis number of the TV, might be able to comment back known common vertical issues.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

This is infact a thermistor. Can you read any of the numbers on the part itself? I don't have the service manual for this model.

COMPLETELY DEAD


Hey !!! I solved my own problem. After I soldered up the thermistor I still had the same problem so I checked all the known parts around the startup circuit including the power supply relay and relay driver. All found to be good so I then attached a scope and signal generator and applied a horiz signal to the base of the Horiz output...voila!! I got high voltage so I tracked the horiz siganl thru the circuit and found a coil to be bad along with 2 electroletic Capacitors. The Zenith part number for the coil is 20-4073-01 and its part # on the board is LX3262. The caps are 4.7 Mfd @ 50 VDC located at CX3261 and 10 Mfd @ 350 VDC located at CX3205. I hope this will help someone else.

UNIT IS DEAD.


believe are the two caps., beside the large H.V. transformer? Just replace the two capacitors and should be fine, I have this problem before. Now as far as open neutral there maybe other damage to the set.

Zenith A32B41W Ground


The 1000pF 2KV caps in the Zenith sets are notorious for burning up. I have seen it many, many times. The ground "plate" you describe is a dual spark gap, between the tuner ground and each side of the AC line. This part literally does nothing until a bolt of lightning hits very close to your house. Even if it shows signs of arcing, it is still good and does not need to be replaced, unless it has melted into a blob of goo and that never happens. The silver part you describe is the degaussing thermistor. It only works for the first half-second when the set is turned on, demagnetizing the picture tube. If you do not replace the thermistor, it is possible that when you move the set you will see that the colors are not quite right in the corners of the picture. If you are careful you can solder the legs back onto the thermistor, but they love to crack when heated with a soldering iron. Bring the broken one to your local TV shop and they will most certainly have many new ones in stock.
