Question about Toshiba 32A41 32" TV
Our tv was accidentally dropped face down and now nothing will show up even when I switch video or change the channel. Is there something I can do to fix it at home or should I take it to a repair place.
Although CRTs are pretty tough, depending on the height of the drop, it may have lost vacuum.
If it is the CRT, I think you would find the replacement cost unreasonable.
If a CRT loses its vacuum suddenly, it will normally show some signs of the phosphor of the screen flaking off spotwise.
Look for this before bothering to go any further.
Leave the set unplugged overnight to ensure that there aren't any dangerous voltages exposed.
Then, what you can safely do at home is to place it face down on some carpeting, remove the few screws holding the back panel on and do a thorough visual check of the guts.
The CRT can retain high voltage for several days; while this isn't necessarily lethal, it can burn a hole right through a finger. If you have a bit of flexible copper wire, you might want to wrap bare ends around a small screwdriver shaft and attach the other end to ground, any bare metal of the chassis.
Slide the flat end of the screwdriver under the large, flat, rubber cap located on the CRT. This cap will have a heavier insulated wire connected to it that supplies the accelerating voltage to the CRT.
The base of the CRT will have a board plugged onto the base of the tube with a number of wires attaching it to the main board..
Carefully remove this board and plug it back in again.
Using good light, inspect the main board and any other plugged connections you can find.
If you can access them try to remove and return them to their mating connector.
Use caution; the boards used for TVs aren't very durable so try to avoid stressing them while doing the above.
If you see wires not attached to anything (unlikely), search for a mating connector.
If your time has produced no positive results, you will have to consider whether the set is worth the cost of an estimate, assuming you can find a repair shop still in existence.
