I have a (10 yrs old - and not used for 3 years) Sony 29" TV, which seems perfectly fine, except that I cannot seem to tune the TV channels either manually or automatically. The TV works perfectly as a monitor for my DVD player.
But I cannot seem to receive any of the free to air channels that I used to be able to get. (In Australia at this stage we have 5 free to air channels broadcasting in Analog UHF/VHF - though I think we go fully digital in 2010).
I have connected an old rabbit ears antenna (which works on my other smaller TV, so that seems OK). But no real signal shows up on the larger screen - just a vague black and white signal from only one station.
I am at a complete loss to understand why this is loss of signal is happening. All I have been able to come up with is that I suspect that the removalists who took the TV out of storage may have slightly knocked the aerial (coaxial?) input slightly, as it no longer seems exactly perpendicular to the set. The connection is not mangled or anything, just slightly off centre.
Could that cause this problem? Could some wiring internal to the aerial plug have been dislodged, and therefore the signal is not getting to the automatic tuner?
It sounds like you have identified the the correct problem, as the Coax connector has probably been knocked loose from the circuit board inside the TV. If you have any knowledge on this sort of thing you can take it apart and re solder the connections. If not I suggest you take it to be serviced by a professional.

no ....the tube will end up after 20 yrs in 10 yr old sony... it is worth if u fix it. randomly going black means...horizontal driver trans former is the problem..or any loose contact with the 110 volt supply to that transformer,,or any loose contact with line o/p transformer.. (horizontal driver transformer may be gone then tv behaves like this) if any other parts gone tv wont come back.... there may be a loose contact call a service pro..
There seems to be a failure in your output drive circuit. All electronics fail suddenly and don't show any signs until the defect is noticed except in the cases of intermittent troubles From what you have described an intermittent defect is not the culprit here. Are you using external speakers or the internal ones in the set? If you are using external speakers disconnect them and see if the internal speakers work OK. If it's both channels at the same time it's in the electronics, not in the speakers. This would require internal service. Unfortunately there is no easy fix for that. Have it diagnosed (which they can't properly do in your home unless it's a very obvious problem) get an estimate first. Those sets are very well made and reliable but nothing is perfect. You need a service call or move it to a shop.
I have a Sony Trinitron 32 color tv KV 2168MTJ (quite old - 10 yrs old), and the standby light blinks exactly 200 times (just over 3 mins) before it turns on. Once it is on, it works perfectly. What's wrong with it and how can i fix it?
If there is no cable switch anywhere (make sure you check the back where the cable screws on) you will have to have a converter box to change channels with. When using a converter you put the TV on channel 3 or 4 and switch channels on the converter. Thanks
Well you going to need a new tuner! Let me tell you now that digital is out or is comming your not going to find the part!!! Well if this has RCA inputs your in luck you buy a digital box around $60 bucks then put the tuner on it and you in luck and you saved your TV!!
