It is the set's brain trying to boot up. (not unlike a computer) These sets if unplugged and power applied should blink 70 seconds and then go out and then can be turned on.
The model number will determine my answer/suggestions=
Models beginning with WD are nasty if this problem.
Models beginning with WS are not quite so nasty to deal with.
IF model number posted is correct and green power light comes on for a few seconds and then goes off: On front of set press and hold both the Menu and Input (device) buttons at the same time for at least five seconds and release both buttons.
Power light will then blink a two digit error code like 2 blinks, 2 blinks, a pause and repeat it several times.
Let me know what error code is found and I will tell you what it means.
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.
It's probably a write-off. The circuit board inside has been cracked so that some of the copper traces that connect parts have broken. This commonly happens around the area of the horizontal output transformer, which is heavy. The shock of the fall causes the transformer to bounce and breaks the board. Other areas too may have been damaged because of flexing. And worst, the picture tube can be damaged in a fall, so it either doesn't work at all or shows permanently distorted colors.
It's tough to find anyone willing to repair a set that's fallen. Many circuit board tracks are very narrow and hard to repair. Then it's difficult to know if all the damage has been found and repaired, so even if the set starts working a technician doesn't know if something else won't go wrong. And then there's that bad tube possibility; no technician likes to spend lots of time fixing a broken board only to find the set then needs a new tube. Trust me, this has happened to me several times during my career in TV shops.
Your best bet is to use this as an excuse to buy a new LCD or plasma TV. 40-inch models, a good size match for a 32-inch CRT (tube) model, are reasonably priced.
This T.V. more than likely has a bad lamp. I don't know the model number so look up on ebay for a lamp replacement by model number after you inspect it and find it to look cloudy or exploded.
It probably has a cracked circuit board. If you want to repair it on your own open it up and see if you can find where that cracked section is and see if you can resolder it back properly.
