Recently my girlfriend's Toshiba 19a21 took a fall about 3 feet from a wobbly table and landed screen-side down. There were no visible marks and the screen remained on, however, it would not change channels, turn off, or play sound from either the buttons on the tv or remote. We opened it up and did not see any blatant issues. When the plug is put in the wall you can hear the normal charging sound, but the tv won't turn on. Is there any way to fix this-- a part that's likely broken or perhaps a torn connection?

Re: fell, won't turn on
For sure the main board its broken and 80% chances that the picture tube has some internal damage that may can cause a rainbow effect, discoloration or color shadows. if you want it to try you can find the broke line traces on the main board , you can buy some tools at any radio shack store , and follow intructions . but its your bet to try the risk to have that picture disoloration and or learn some electronics

If your table has feet that look like the screw in, then youshould be able to adjust the feet on the legs of the table by tightening themall. To so you should ensure that the table is flat and see if any of the feetare off the ground, if so you should adjust them so that they are touching thefloor on all sides.
After a fall like this (even on carpet) it probably has a cracked circuit board or a loose connector, first (since you took it apart any way) look for all connectors, than unplug them and re-plug them to make sure all plugs and boards are seated correctly, if you still don't have luck, than take out all the circuit boards and check them for cracks under a good lamp and magnifying lens, than repair the cracked traces with a good soldering gun by scratching off the varnish coating and applying solder. (if the crack is to wide you can solder a peace of coper wire to the trace on the board)
Belt falling off,, It is most likely a belt tencher, or a pulley,, Turn pulley's by hand felling for any wobbling or play side to side especially watter pump ,if fault is found replace part and reinstall belt,!if you cant find fault,Reinstall belt,then pull on belt to see if it belt has tension and returns with no sticking of tension-er then,if all look well .start car and observe ,may have been a glitch or bad belt best wish
Please handle your PC with care. Since it fell abt 6 in., it must have some connection problem that will still be repeated as soon as it bangs. If it doesn't work in few days from now, check the HDD it may have caused damage because of the fall. Then if you can open any board, unplug connections from outlets then press soldered connections in the motherboard.
Just a pre-caution. But if it persist, see your supplier's technician.
It happened 2 months ago on my phone after it fell 3 feet high.
Surprisingly after intentionally banging the phone face first on my
table (keep it gentle) it worked and has been OK ever since. I hope
this works for you too. =)
What safety steps do you take when driving a car?
The crankshaft oil has been mixed with the gasoline insde the piston cylinder. Drain the oil and replace, as well as remove the spark plug and pull the engine thru a few times.
sorry to tell you, most likly when the set fell, it caused a screen inside the set called a shadow mask to shift and the only way to fix would be to replace the picture tube. you could try unplugging the set overnight then replug back in but its unlikly that will help but always worth a try.
