This is fairly straight forward---if it got the fuse, input filter (big cap!) and the fuseable 7 watt-----

Understand (I do not know how savy you are) the power supply uses two grounds----on the primary side of the transformer (in power supply) it is from earth ground and on the secondary side from hot ground--when checking voltages= these are the key! you have to be on the correct ground to get correct readings.

Follow the money---the primary raw should be on that cap---follow it to see when it stops downstream.

220 can pop a lot of things---the set should also have a regulator IC in the power supply (could also be a big transistor) and if a chip--raw from that cap goes into it---and regulated comes out another pin---see if you have the raw and then see if at horizontal output collector and from there to flyback( with set off what is resistance reading from the collector of the output transistor to earth ground?

what kind of experience do you have with troubleshooting?

SOURCE: Main fuse blown on CT-32G11 32" Panasonic TV, Replacement fuses continue to blow.

If the main fuse keeps blowing, check the horizontal output transistor for a shorted condition and diodes in that section as well.

SOURCE: picture shrinks horizontally every few seconds.

You are changing parts in the wrong circuit. The problem is in the vertical circuit. Look for the vertical IC and resolder the pins first. It should be an LA7837 or something similar. Also, check the 100ufd and 47ufd caps in the same circuit.

Keep us posted.

Checking a fuse I get .4 ohms for continuity does that mean I will get 1.4 for a bad fuse cuz that is what is happening. If the contacts are connected I get .4 and when they are not I get 1. When I

You cannot check ohms with circuits that are connected together. Also with electronic circuits it is not recommended to do continuity tests with the meter as you could damage these. Also depends on what type of fuse you have. Please provide make and model of dryer and which fuse component are you looking at. Someone who is familiar with that model might be able to help.

My LG Flatron rear projection TV won't turn on. The on/off power button is not turning the TV on. There is no click sound and the red light doesn't come on. The TV is connected to mains power and ther

tried with other ac outlet doesn't work?. if still won't turn on, at this time you will need to remove the rear cover to gain access the internal part. since your tv doesn't have any power indicator, the first place to be checked will be the power supply board this is where the power connector cord is connected. now look for a blown fuse replaced with the same rating. but take note before you replaced the bad fuse you must need to have component testing in the power supply board which the cause of blown of the fuse. like shorted bridge diode, open resistance and defective mosfet or bad regulator ic.at this time you will need a device called digital tester to check weather the parts need replacement.hope this can help good luck.

Incoming Power Problem If the washer won't start check to see if there is power at the electrical outlet which the washer is plugged into. Plug a lamp or radio into the outlet to check it. If the outlet is dead, check the circuit breakers or fuses for the home.

Power Cord If the washer won't start, check to be sure there is power to the electrical outlet for the home. If that is OK, the power cord itself might be defective. This is rare. You can check the power cord with an Ohm meter for continuity.

What's your problem?the tv won't turn on i check thehorizontal trans and its fine i check the power and everything but nothing

Check the horizontal driver transformer. Measure the frequency at the base of horizontal output transistor. It should be around 15.6 KHz. If there is no frequency measured at this point, horizontal driver transformer, horizontal driver transistor, and horizontal oscillator section should be troubleshooted.

I accidentally overheated my Panasonic Plasma TV TH-42PZ700U. It won't turn on, and the power button blinks TEN times.

Check and see if there are any blown caps on the power supply. If there are replace them or change your power supply.

So after getting my car back for the garage my subwoofer isn't working I checked to make sure all of the connections are correct and the settings are there why won't it work

Check to see if your amp is on. You may have blown a fuse somewhere maybe on your amp. Check for proper voltages and make sure the sub isn't blown by pushing on it. If you feel unequal resistance, you probably blew it. Also check the ohms on the woofer.
