There is a short somewhere on the board causing the overload. You will have to get the power supply checked.

You have short circuits, need to check the bridge rectifier, MOSFET that drives the AC to DC converter, etc. You will have to do component level repair at this point, better off getting new power supply module.

SOURCE: the fuse inside the tv has blown so tv wil not

The main fuse is found on the power board which is a the front end of the power supply. Now if the fuse has blown you can replace with the same rating fuse which can be pruchased from any electronic store. All what is needed is to confirm the value of the fuse and replace only with the same rating. However if the fuse blows out again then it is confirmed that the SMPS- the power supply unit - has failed. If so it is important to look into this circuit to recitfy . attempt only if you are technically able.

After a power outage, the tv wont turn back on. was hoping there is a fuse that may have blown.

Hi Michael,
Yes there is a fuse in your TV too and sometimes you do escape with a blown fuse after a power outage. Please open if you can the back cover of your TV, locate the fuse. If you do not see any damaged or blown parts, replace the fuse with the same rating. If the works, enjoy watching. If the fuse blows again, the power board needs to be repaired or replaced.
Good luck.

Sylvania LC321SS9 B 32" LCD, won't turn on

Hi Stephen,
TV won't turn on means the power supply section is dead. Open the back cover if you can. Check up for the blown fuse. If the fuse is blown, replace a new one of the same rating. If the TV works, enjoy viewing and if the fuse blows again consult some TV tech. Never try another fuse with higher rating. It might seriously damage your TV. Good luck.

Tv wont turn on

does the power indicator at the front panel blinking or in stand by mode. if no any indicator, look for the power supply board where in the power cord connected. replace blown fuse but before replacing new fuse make sure no other bad component like burnt parts or shorted. the fuse will blow again unless no other defective parts.

Open your TV and chekc whether the fuse in the power supply board has blown out or not. If it has blown out, never replace it with same type; befor troublshoot the reason for the blown out for the fuse. There must be some reason for the fuse to blow out. Without rectifying it, if you replace it with a new fuse, it may cause more damage to the set.
The power supply board to your TV will look like this.1_10_2012_4_00_19_am.jpg

I try to turn the tv on but there is no power.

check the incoming power with a tester and if ok then check the plug fuse and if burnt replace and if ok proceed to open the tv cover and check the cable continuityand check the fuse in the power supply region if blown, check other components inthe power supply area and replace the faulty ones if any then open the fuse in the power supply and connect a 100w test lamp to see if there is a short circuit. if the bulb lights up and gets dim gradually you ca now remove the lamp and put backthe fuse and test again

however, your tv problem could be solved by simply replacing a burnt fuse but its always advisable to verify the cause of the blown fuse

Power surge I think

If you do not get any clicking or sound when trying to turn on the TV set, most likely the main fuse went out. This is almost always due to something else blowing out along or making the fuse to blow out. DO NOT SIMPLY REPLCE THE BLOWN FUSE! If there is other shorts inside the set, and you replace the blown fuse, you can cause more damage to the TV set. The best way to test this set if the fuse is blown would be to hook up a 100 to 150 watt light bulb across the blown fuse, and if there is a short in the TV set the light bulb will glow bright and stay bright. If the bulb lights up and goes dim maybe just maybe you got luck so replace the fuse and see what happens. If the light bulkb stays bright, there is a short in the set somewhere and if you do not have a service manual and a good multimeter and a knowledge of how the TV power supply works, you really should call in a pro to assist you in the repair of this TV. there is just too much High Voltage inside these TV sets to be experieenting around inside of it. Good Luck.

TV will not turn on when power button is pushed.

check the main fuse in the tv. test it with a multimeter, not visually. if its the thermistor that blew the fuse, it is very difficult to see the break in the wire. replace if blown. if unit blown fuse again withing a couple of weeks replace the thermistor in the degausing circuit. good luck.
