If its not transmitting or receiveing its probably a problem in the power supply or antenna/coax.The big transistors you see inside are the output transistors for the transmitter section and would not effect the receive. Does it pick up static with the squelch is open? if so the audio section probably works ok.Have you tried a watt meter with a dummy load to see if the transmitter is working?Before you change components you have to narrow down what section is not working and know why its not working otherwise the new transistors could just blow too if its transistors that are bad.more information is really needed to diagnos the problem.

R58 and driver smoked.

Could be that the PA is also shot. ALSO, check your antenna switching diodes, they quite often open and/or short which can cause lots of problems. Check your current drain in transmit. It should be 2 to 3 amps in transmit, and about 1/2 an amp in receive.
Check the collector voltage on the PA transistor. It should be 13.6V in transmit. Also, in some radios, there is a diode between the DC input and the final transistor. I have had to replace this in a few 29LX's.

Can you see the s-mete if it has one moving up and down on any channel? Do you hear any audio at all? could be a couple of things. Bad mic switch or mic cable, bad antenna or coax, bad audio amp. To check the audio amp plug in a speaker to the PA jack, put the PA switch on PA then press the mic to talk. If it works the audio is fine the mic is good and the mic cable is good. Noiw plug the speaker into the speaker jack, do you hear anything? If not then your antenna or coax has a problem, fix or replace antenna or coax.

Key to tx-green lite out-no output power or red lite rec ok

It could be small transistors--in the back where the light and transmit hook up. One small transistor will shut down transmit & possibly receive. Get it serviced at a radio repair shop. if you know how do it yourself. Change all small transistors to 2sc3904 or 2sc 3906 at "Radio Shack."

I have a realistic TRC-418C.B. Model#21-1511A I can recieve but not transmit. What should I be looking for??? I let some one barrow it and they FLEW home. could the airport scanner done some thing?? Also...

Sounds like it burnt a final out. Its a 3 prong transistor near antenna out. Its mounted on a heatsink. Look for 2sc2078. Radio Shack will sell these or order them. If you want to solder in a new one. Disassembling the antenna can cause SWR which will burn up your transmitter. Make sure antenna is put together properly.

The wire broke off my aerial and the transmit button was pressed with no proper aerial, mended the aerial, now I get an SWR reading on my meter of 1.2 but no power output reading and no reply's to calls !!...

it sounds like u fried your final.. Its only your driver/buffer transistor that's working right now..
if u can identify them usually large square transistors close to the aerial conn,
look for # on front of transistor buy replacement and replace . if your handy with the iron it should be a cake walk.

Talkabout T5800 (22 Channels) 2-Way Radio: droped in water will not transmit but will receved...

Depending on the type of microphone used, if not the type using the speaker as a microphone, it may be damaged. I would though, suggest you remove the battery, open the case and allow the innards to dry in a warm place for several days. Even daily exposure to the sun should work fine.
