I would check for blown capacitors! These look like AAA batteries but a much smaller size. Many times their tops 'silver' are puffed up 'bubbled' or even popped off. These are at voltages of 4.7 Volts DC and or even 12 Volts DC and even some larger ones at 24 and 50 Volts DC.
More than likely either capacitors have failed or possibly some other component such as a transistor has burnt up went out.
May be a good idea to find a part # for the main power supply and look on the web for a place to get a replacement part. I believe Protron is a part of Magnivox

Gas dryer checked ignitor, thermal fuse and flame all had continuity still ignitor will not glow or heat


Will try to help you checked the igniter you say good if good does it glow if so clamp on one wire and take an amp draw while heating I like to see a minimum of 3 amps if glowing and 3 and above change the coils on the gas valve very cheap, now if not glowing and good ignitor the fun begins power comes out of the heat relay on the control board passes thru the thermal fuse then thermal cut off then hi limit then the flame sensor while also feeding the gas coils the neutral is supplied thru the centrifugal switch on the tumbler motor if the dryer stays running the centrifugal switch is good and you have a neutral bad flame sensor very rare since I am not there check the thermal cut off once blown it does not reset has to be replaced if all the fused I mentioned check good then check the heat relay on the board black and red wire stick meter ends in both off should read 120 volt when machine turned on should hear it click and meter should read 0 volts the boards seldom go bad but I have replaced a few in 5 years I am leaning more towards an open thermal cutoff

Don't have sound watching tv, but have sound when dvd


Download its user manual, and check audio settings. Refer it. If all settings are OK, still no sound output with on-air programmes, teh sound detector section has the fault. Seek tech support. This is a skilled work, and need all measuring instruments and through knowledge in electronics.

My Pfaff 1471 lights up, but does not run. This model has no fuse. I checked the foot pedal with an ohm meter, & it sends a variable signal. My house took a direct lightning strike 2 weeks ago, &...


Were the base plate pugs into the power leads, you should read about 6-18 is ohms. Open and short is a bad transformer.

Also there are fuses, 2-3 right next to the transformer, small blueish and round are the shapes. They go bad often.

I heard small pop then lost power while watching my lg 50pg20. No red or blue lights on the power switch. What could be wrong?


you are describing a power supply defect. IT may be as simple as the main fuse. I believe the one in this set is a 6.5 amp located on the ps board right by cord connection. IF after replacing the fuse opens a second time you will need to replace the power board.

Pop sound then no picture, just sound


I assume this is a plasma TV? You will have a fuse blown on either the Y or Z sutain board, there is also a possibility one of the driver IC's has blown on the buffer board, this will shut down the screen & leave the audio working normally. You can check these boards which sit on the left & right hand sides of the screen.

Brake lighs stop working


Does the 3rd brake lamp illuminate? If so then your problem is multifunction switch.If it doesn't do the following checks.
Check for power to and thru the brake lamp switch itself.If you do not have power to the switch check fuse no. 10(20 amp) in the interior fuse panel.If you have power to the switch then depress brake pedal and make sure you have power thru the switch.If this is ok the check Fuse 22(20amp) with brake applied..

My TH-42PX6U TV went completly dead


Ok, I hope to save you a lot of money. I finally figured it out. There are a lot of hints on the web. Once you get it fixed you will regocnize them. So here is what I did. Had to order the 2 fuses for the main power board from panasonic. The fuse number is K5D802BNA005. You only need two. Once I changed the 2 fuses I go the tv to power up but the red light blinked 10 times. This indicated there is a power problem.
There is a high probability the P board is bad. You can check this by checking th voltage on the number one pin on the p10 connector. TO do this you have to measure the voltage as you power the TV up. you should get 14 volts. if not the board is bad. I bought one on Ebay for $120. Put it in and it works. good luck.

Tv won't turn on


KLV-32/40U100M (Dead, no lights), Solution, either replace or remove U24 uP reset chip on top of board, by (SW-1) silkscreen, I suspect, this is the common failure with dead units. Recommend
replacing U24, but should work fine without it. Why pay more!
