Re: sony trinitron KV-1800UB
It's probable that your set top box does not have an RF modulator needed when receivers don't have a Scart or phono video/audio sockets. The aerial/output sockets on your set top box are simply aerial pass through. Hope this explains your problem. John.

Re: sony trinitron KV-1800UB
There aren't many that do have RF out, and most of those are quite old now.
It's usually best to buy a stand alone RF modulator (make sure it's for UK use) which is relatively cheap and easily available on line. Otherwise use an old VHS recorder (try a charity shop or Freeecycle) which will probably have a SCART input and RF output. The deck itself doesn't actually have to work. |

Re: Sony Trinitron KV-1800UB
Another pitfall is that many of the last generation of video recorders don't have a modulator either as most TV receivers had scart sockets fitted! You will be safe with anything produced in the 80's to the mid 90's.
If your not sure we can probably advise. John. |

Re: Sony Trinitron KV-1800UB
Hi.
Some VCR's can shut down too if left on without a tape running (E to E mode). The modulator is the neatest way of doing this TBH.

Re: Sony Trinitron KV-1800UB
Connection is easy. You'll need an RF lead (coax lead male to female) and a SCART lead.
Just run the coax from the VCR's RF out socket to the TV's aerial input. If your VCR works, then play a tape. As you do, rotate the tuning knob on the Sony. The output is usually (though not always) around channel 36 on the dial. If this works, then your VCR is suitable. Connect a SCART lead from the set-top box to the SCART imput of the VCR. Select the aux input (maybe EXT, L1, A1 or similar) and it should work. If you don't have a SCART socket or you don't get a picture when tuning, your VCR might not be suitable as John says, so come back to us and we can help. |

Re: Sony Trinitron KV-1800UB
Probably a capacitor drying out which will need replacement. From your post it sounds like you'll need to find someone to sort it out for you. Might be worth posting on the 'repair Services Wanted' on the forum - there might be someone nearby.

Re: Sony Trinitron KV-1800UB
If you've selected the correct input (AV1, AV2 or whatever) on the VCR and just get a blank screen then it's likely your digibox is set to RGB output whereas your VCR wants CVBS (PAL Video). If you connect your digibox to a TV that can display the output then go to the menu and select CVBS or video as opposed to RGB in settings. Then it should work.

Re: Sony Trinitron KV-1800UB
Can't remember if it's the 1800 or the 1810 that had a cap decoupling the colour output stages. 200v rating it was, I would look around there though.

Re: Sony Trinitron KV-1800UB
Going back to your post #12 regarding the Sony, I'd find it odd that the tube has failed after storage. Much more likely is Tony's suggestion of a decoupling capacitor.
Of course the tubes in these were pretty short lived so it's likely the repairer said it's not worth repair as when it's done the picture will be poor anyway. Worth keeping the set though. |

Re: Sony Trinitron KV-1800UB
That VCR is a Funai which are a law unto themselves and may have cut corners with the AV switching. Any chance you could find a different VCR? Doesn't have to play, just loop the AV input through to the RF.

Re: Sony Trinitron KV-1800UB
Hi Glyn thanks again I'll see what I can find might splash out and get a modulator.
