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. doesn't use a lamp. If you're referring to the picture tube, there is no fixing this other than making slim adjustments on the knobs on the flyback. Don't tweak it too much or it will cause retrace lines. However, in most cases a bad picture tube means its time for a new T.V.
the power supply of your tv is bad try to check the fuses if fuse are open try to replace them with the same value..try to power it on but if the fuse blows again replace the power supply board...
good luck plse rate my help.
What other device are you connecting to your tv and how are you connecting it?
If you connect via a single HDMI cable that may be causing your audio problem. Some Tv and STB have handshacking issues which can knock out audio and/or video. The only solution would be to replace the HDMI cable or switch to composite cables.
It sounds like the picture tube may be weak (because it's orange) but it going to half ascreen is not caused by the picture tube but likely a vertical circuit problem. If this problem happened suddenly (going orange) then the picture tube is probably good and at least worth bringing in for an estimate.
Check the fuse which is in the back. It should look like a glass tube and the wire inside should reach all the way across the whole tube. If fuse looks good, then the power supply may need to be changed
If you are able to do console repairs I would order a new power switch module the either plug or solder on and switch it out. Without trying the TV myself I might think that the tube could be bad as well, if it is just having start up problems.
I don't want to sound silly here but what is a cpu explain thank you.
