MY R27TNTN MODEL AFTER 30 SECONDS TURNS IT SELF OFF EVERY TIME

I Allready check the resistance R344O (10 ohms 1/3 w) at the CRT circuit board and it is good, I did this because a technician told me
that maybe the problem, He told me too something about an arch in the CRT, will you please help me.
The model of my tv is R27TNTN and I never find information for this model. Tankyou again, Roberto.

Well you did start out good, thats cool, now we have to define focus, Is ir blurry around the edges as well as the whole Picture? If it is, it could be the picture tube, A bad solder connection on the tube socket, and yes it could also be the flyback transformer.

SOURCE: TV set self turn off after few seconds

It sounds like the voltage regulator in your power circuit. Also you have a capacitor that's going bad somewhere and won't hold a charge. That's why the picture is fine for a while then turns green. Unless you service TV's this one will have to be brought into the shop. Unfortunately it'll cost more than the TV is worth to get it fixed unless it's still under warranty. These days TV's that small aren't worth fixing. You're better off buying a new TV.

check for a pot on the chasic board or check yoke if crt.

The problem is most likely you have a bad capisitor or cold solder joint in the primary circuit.
It will look like a half moon shap are dull looking, but look for swollen capacitors first and then cold solder joint second.
a capacitors stores electrons and release them as it need power to the circuit and if it's damage (leaking or swollen it wont ) do so.
Are the regulator break down under a load.
A shorted horizontal output transistor will power up and shutdown with in a few seconds or blow the fuse.
Just a short summary of what's what

Unit stopped cooling. Measured circuit resistance L1 to L2, approx 10 ohms. Plugged unit in, heard a click in a few seconds. Unplugged and measured circuit resistance which indicated circuit open. ...


You'll need a 3-1 start kit. The clicking is those starting components. We shipped one out yesterday for 35.00 and that included overnight Sat. delivery the part alones was 20.00 with instructions. Very easy and the replacement kit is better than the original parts and available at most any appliance parts store. Good luck.

My sony trinitron xbr tv turns on stays on a few seconds then powers off by its self and it gives 5 red blinks from stand-by


This is according to the sony service manual

Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

Sounds like a failure in the C Board or AKB Circuit.

Best to take it in to a service center.

Whirlpool gas range error code f2


Hi sauerteig_j,

Whirlpool F2 error code indicates that oven temperature is too high. And to fix this problem:

1. Look for welded relay contacts on bake or broil relays. If this happens, replace oven control (also called clock or ERC).

2. For SELF CLEAN models: check door lock operation.

3. Look for a high resistance connection or any other cause of high resistance in the oven temperature sensor circuit. Check sensor, sensor harness and sensor harness connection at sensor and oven control. Replace sensor if found defective.

Remember: Oven control (ERC) measures resistance of sensor circuit, not actual oven temperature.

For replacement part you may contact Sears at 1-800-252-1698; M-F 6:30 AM-10:30 PM - Sat 7:00 AM-9:30 PM - Sun 7:30 AM-9:30 PM - All times Central. Just have your model # ready when you call.

Hope this helps.

Thank you for using FixYa.

Our oven keeps randomly beeping and flashing F10 on the display. marcnholly@yahoo.com


Sorry to read about your problem, I hope this helps you out.

F10
Runaway Temperature.
1. (F10 only) Check RTD Sensor Probe & replace if necessary. If oven is overheating, disconnect power. If oven continues to overheat when the power is reapplied, replace EOC. Severe overheating may require the entire oven to be replaced should damage be extensive.
2. (F11, 12 & 13) Disconnect power, wait 30 seconds and reapply power.
3. (F11, 12 & 13) If fault returns upon power-up, replace EOC.

Electrolux Slide-in range model EW30ES65GSD Fault code F11. We press cancel (either once or holding for various number of seconds). Within a minute or two, the code bell rings again and keeps ringing until...


The F10 F11 F12 F13 F14 Error Codes indicate that the electronic oven control board senses a runaway temperature condition in the oven through the oven sensor circuit.
This can be caused by a faulty oven temperature sensor probe or a failed electronic control board.
Oven temperature is detected by the control board as it monitors the resistance through the oven temperature sensor circuit.
You could have a failed oven temperature sensor, a wiring harness failure, an open thermal switch or a failed electronic oven control board that would cause this problem.
The first component to check would normally be the oven temperature sensor probe.
If you have a volt/ohm meter, you can shut off the breaker for the range and remove the screws that mount this sensor to the back wall of the oven.
Carefully pull the wire harness into the oven cavity until you get to the wire harness disconnect plug.
You should have enough slack to pull it this far into the oven.
Disconnect the sensor but do not let the wire harness retract back through the back wall of the oven or it will be hard to reconnect.
Measure the resistance of the oven temperature sensor with your volt/ohm meter. At room temperature, the resistance should measure around 1100 ohms.
The resistance chart is shown in the image below.

If the resistance is above 2200 ohms at room temperature, then the sensor probe is causing the F10 error code and will need to be replaced.

You can order a new sensor probe from the Sears PartsDirect website. The part number for the sensor is 316217002.

If the resistance is normal, then one of the other causes mentioned above is producing your F10 code.
You would need to access the electronic oven control board (Timer) in the console and check the resistance at the sensor circuit connection to the control board as the next step in troubleshooting this problem.

Test to see if circuit board is okay


From Appliance Aid.com

WHY Force the Arctica to Defrost if it Don�t Want to? Don't bother using the self-diagnostics feature to force a defrost cycle. On some models � those with control knobs - which technically are not Arctica models (Arctica models have plastic liners with touch pads � Standard GE electronic models with metal liners have knobs) servicers would have to invest in parts to build a �test� control panel, complete with touch pads and digital displays, to achieve this (self-diagnostics) function. Instead, save both time and money by following this helpful Arctica Tip: If a frosted evaporator or a �frost block� is apparent, initiating a defrost cycle may not reveal anything helpful anyway. First, disconnect power and then simply check the resistance across the defrost heater and bimetal circuit at the main board located at the backside. The two associated wires at the main board are almost always BLUE and ORANGE. The heater/bimetal circuit should normally read around 30 ohms roughly. Next, check the evaporator thermister at the main board between thermister input terminals J1-4 (Blue/White) and J1-5 (Blue) to determine that its resistance is greater than 1.2k ohms but not more than 166.8k ohms depending on its ambient temperature. If thermister resistance falls within this range according to temperature (Approximately: 6k ohms at 70�F � 16.3k ohms at 32�F � 51k ohms at 0�F) and the heater/bimetal circuit is diagnosed as good, then replace the main board.

When switching TV on screen turns white and after 30 seconds switches off


This likely has a 10 ohm resistor on the CRT board that is open.  This feeds 200v to the cathodes of the CRT.
