TV tries to power on but shuts off

My girlfriend dropped my TV on its face, the fall was about 1 foot and onto carpet. When I picked it up I noticed it had come unplugged in the fall so I plugged it back in and pressed the power button. The light comes on and blinks like its going to start right up and after several seconds i hear it click and go off. Any ideas would be greatly apprieciated thank you

Re: TV tries to power on but shuts off

When a direct view set fails after (minor) impact it is usually due to PCB fractures - and then it is usually fractured around the flyback transformer (because of the weight of the component), but may be cracked elsewhere. Patch jobs around the flyback are typically easy. If the board is badly fractured use some stiff wire in the patching to give the PCB some rigidy and prevent further aggrevation of the fractures. I would assume you did not bust the picture tube as you would have heard that one :) If this is one of those vcr/dvd combo jobs then you may have to look elsewhere for the fractures.

32" TV fell over onto carpeted floor and won't

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.

Dropped tv 5 inch on its face while moving. Tv

It is highly probable that the main board is cracked due to the drop. An experienced TV repair person can run jumper wires across the cracked board. You can verify this by opening the back of the tv up and pulling out the main board and search for cracks on the bottom of the board.

Rainbow pattern on CRT TV

If degaussing doesn't work, it may just be time to pony up and replace the crt as it sounds as if the shadow mask inside the tube has come loose. And, as you know, there is no opening that to service it.....accordianman

Dropped TV!!!

Worth fixing? Sorry, probably not. My experience with problems like this are such that the set will keep being repaired as new issues develop. The click and shutdown are a safety feature and are kicking in for a reason. Take what you'd spend on repairs and get a new TV. It will be cheaper in the long run. You might make some $ back by selling the set for parts. Who knows? Hope this helps.
