have you checked the DC side of TV LOOK FOR ANY CAPACITORS with holes blown in them and are a of a burnt appearance , and also look for any breaks in circuit board also look for holes in circuit solder . I know this might sound silly have you checked the fuse in the MAINS PLUG ....
Most likely the power supply. In most models, if the lamp goes out you will still get sound.
However, the power supply is not a single piece swap. I would suggest getting a voltmeter, and check the voltage where the power cord meets the power supply. Then follow the circuit pathways, checking after each component, until you find a break in power. You are getting power to that light, so some power is getting through. However, the light works on much less voltage than the rest of the television, so probably there is a capacitor or transformer that's gone out.
There is an intenal fuse with every tV. You haven't given any details about your TV, such as its Brand Name, Model number etc:- Open the set, and locate this fuse at its power supply regualtor board. if found blown up, check the reason. you must have through knoledge in electronics to follow the circuit.OK.
Hello There is a fuse inside the power supply bard of your sylvania TV. Check whether it has blown out. If bllown out, replace it with same type bothe in size and amperage. If the newly inserted fuse also blow up as soon as you switch on the set, make sure that the power supply section has some short circuit in it, and should be cheked well. OK.
Hello If the TV doesn't turn ON ata all, it is surely due to some fault with its power supply regulator section. You haven't given any otehr details of your tV, than it is only a 32 inch CRT Sylvanial Tv. No model number; so I only can provide you a solution in general. Check the ON-OFF switch for its contact. Normally, TVs uses DPST type switches [Double Pole Single Throw]. If any one contact amoung them have any problem with its internal contacts, the set won't switch ON. If the switch is OK, come towards the power regulator section circuit board, and check whether the fuse has blown out or not. If it has blown out, replace it with same type and ampere rating. Never use higher ampere rating than specified. The ampere rating will be maiked either on the rims of the fuse, or at the printed circuit board, just under the fuse. After repalcing the fuse, switch ON the TV and see whether it works well or the replaced fuse blows up as soon as you switch ON the set. If the repalced switch burns out as soon as you switch ON the set, the power supply section has damaged [shorted components in it]; and should be replaced. Normally for LCD TVs it will be good to replace the power supply as card basis. This power regulator card can be bought from most of the electronic spare part shops at your town, orby the authorised service center for Sylvania at your town. If you may have given its model number, I could send you the picture of the power card of your TV. OK.
A dead condition usually indicates one of the following: Open fuse (often internal, and usually pops due to other circuit defects). Short (overload condition) in the circuitry. Failure elsewhere in the circuitry. Most modern electronics have some logic circuitry, and if there is a section of the circuit not working, the logic circuit keeps the set from coming on at all.
First, if your power cord plugs into the set, check that it is properly connected. If you can get into the internals, find the fuse, check it, replace with an exact or near exact size.
If problems are beyond the simple, technical expertise will be required to nail down and fix the problem.
A blown fuse is usually caused by a shorted regulator or a bridge rectifier circuit. Either way it is a problem in the primary power supply.
A bad cord won't blow the fuse in the set, it will blow a circuit breaker in the house.
A servicer usually would normally cover the inside of the set with a "few light slits in the AC cord".
Hope this helps
