Check its main power regulator board. Check fuse. Check and repalce damaged component/s.
SOURCE: I have a 32" CRT Sylvania Tv that won't turn
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.
