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.
do you mean the power indicator at the front panel doesn't light.ok this kind of trouble is in power supply section since the stand by doesn't work. the first place to be check is the fuse if blown. if blown with darkened color that was an indication that has other component part that get shorted. at this time you will need a proper trouble shooting using the a device like a digital or analog tester. if you don't have enough idea on how to do the job and necessary tools, just send it to the trusted service shop to fix the problem.thanks for using the fixya.
try moving the antenna around as it is the most common problem where i reside and most of the time when people buy a new TV with an antenna, they have to set it up where it can catch proper network.............or if that doesn't work then i prefer that you take your TV to a technician to check out the fuses.
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.
First check the fuse in the fuse box for signal light, replace the fuse with similar value if it is busted. If the fuse is still intact the problem would be the flasher relay( small cylindrical aluminum ) that is already malfunctioning.
This is alimentation fault of the amplifier inside the box. Dismount the amplifier block and take a look first if there are some burned pieces. If it seems all ok, better bring it to a electronics/ tv service center.
