Question about Televison & Video

Sylvania LC155SL8 tv does not turn on. Internal fuse is ok, there is 120 VAC input but only 10 VDC at 30 VDC test node. I do not have a schematic or service manual at this time. Any help would be appreciated.

It seems the power supply module is bad. You should be able to change it no problem. Order the part.

Do I have to replace the control panel on the oven if it isn't lit?


Without a full schematic, and an understanding of electrical wiring, you have no idea if the internal 120 vac light is even on the same circuit as the control panel. Electric ranges are generally powered by 220vac, which means that both 120 lines are run through the unit.

you could have full power to the appliance bulb and have a blown fuse to the control panel, how much of the range actually functions at the moment would be important information to share.

Dead battery 1990 xlh sportster 1200


The voltmeter test provides a general indicatorof battery condition. Check the voltage of the battery to verify that it is in a 100% fully charged condition. If the open circuit (disconnected) voltage reading is below 12.6V, charge the battery and then recheck the voltage after the battery has set for one to two hours. If the voltage reading is 12.8V or above, perform the load test described below.



The load test measures battery performance under full current load and is the best indicator of battery condition. Load testing a battery tat is not FULLY CHARGED i.e. at 12.8 VDC can permanently damage it. Fully charge it first and then let it stand for at least an hour before the load test is done. You also need a load tester. AND you should know how to perform a load test. Often the best way to load test a battery will be to take it to a battery shop and have it done there.



VOLTAGE (OCV) STATE OF CHARGE FOR AGM BATTERIES IS:

12.8 VDC = 100%

12.6 VDC = 75%

12.3 VDC = 50%

12.0 VDC = 25%

11.8 VDC = 0%



COLD CRANKING AMPERAGE (CCA) for a DYNA battery is 270













19 AMP HOUR BATTERY =



BATTERY STATE OF CHARGE = 12.8 VDC = 100% Charge; Rate of Charge = N/A



BATTERY STATE OF CHARGE = 12.6 VDC = 75% Charge; Rate of Charge @ 3 AMP = 1.75 hours @ 6 AMP = 50 minutes @ 10 AMP = 30 minutes @ 20 AMP = 15 minutes



BATTERY STATE OF CHARGE = 12.3 VDC = 50% Charge; Rate of Charge @ 3 AMP = 3.5 hours @ 6 AMP = 1.75 hours @!10 AMP = 1 hour @ 20 AMP = 30 minutes



BATTERY STATE OF CHARGE = 12.0 VDC = 25% Charge; Rate of Charge @ 3 AMP = 5 hours @ 6 AMP = 2.5 hours @ 10 AMP = 1.5 hours @ 20 AMP = 45 minutes



BATTERY STATE OF CHARGE = 11.8 VDC = 0% Charge; Rate of Charge @ 3 AMP = 6 hours, 40 minutes @ 6 AMP = 3 hours, 20 minutes @ 10 AMP = 2 hours @ 20 AMP = 1 hour





The figures listed above assume that the battery is charging at room temperature. If warmer than room temperature, use a slightly shorter charging time. If colder, use a slightly longer charging time.



The use of constant current chargers to charge maintenance-free batteries is not recommended. Any overcharge

will cause dry-out and premature battery failure. If a constant current charger is the only type available, do not exceed the charge times listed above and do not continue charging the battery if it gets hot. When charging, never exceed 15 volts for more than 30 minutes.



If the battery gets hotter than 110 degrees F. (43 degrees C) during charging, discontinue charger and allow the battery to cool. Overheating may result in plate distortion, internal shorting, dry out and/or other damage.

Sharp Model LC-37BD60U : There was a thunderstorm in the area. The Direct TV receiver is O.K. but the TV will not turn on. I have 120 VAC at the 2 pin plug where it plugs into the television. I have tried...


Hi,

Most likely the Internal Fuse has blown
You can buy replacement for very cheap
The Fuse will be located on the power supply board

You will need to remove the back panel of TV to get to the power supply board
Usually it will be a t4 250V in UK
You will have to take the fuse out and look at it as all TV's are different

If you dont have a multi meter to test the fuse you can turn up your stereo loud and touch one end of the fuse to the 3.5mm audio Line out and the other end to your finger, if the stereo buzzes it means the fuse still works


Goodluck

Why won't it turn on?


Sounds like you need a new battery. When they go dead you will still see the green light but it will not turn on or only on for a second.

I have the power cord dvd cords and cable cords plugged in and there is no picture the tv wont turn on it should turn on but it wont it wont even show that its off


Have you verified #1 that your outlet is putting out 120 VAC? Have to checked input power fuse inside chasis? What about a stuck power on switch? Unplug all access. except the TV and try powering it on.

I just received this kenwood 100 watt powered sub w/10'' sub from a friend... he says it just won't turn on, i checked the fuses and they seem ok to me just won't turn on like he said... can someone help...


check the transformer has ac around 50 vac. then check the dc power supply at +_ 45 vdc if all that is ok,check the output ic has +- 45 vdc at 2 of the pins,if it does,the output ic is probably no good

Fuse missing


I would start with a 1.5 AMP fuse (175 watts / 12 VDC = 1.6 amp)
Make sure the fuse is rated for at least 120 VAC. Hope this helps!..Gary

Tv/dvd will not play when use ac plug


The 120 VAC to 12 VDC transformers they supplied with the TV are VERY prone to failure
