Re: Philips GR1AX space helmet tv.
You need one with an RF modulator. I believe the Goodmans GDR11 has one
looking at the user manual (download it here) https://goodmans.zendesk.com/hc/en-u...R11-User-Guide Check that the modulator output is set to UHF and try various channels. You need a female to male flylead between RF on the STB out and the aerial socket of the TV

Re: Philips GR1AX space helmet tv.
If the set was once used with a VCR it is likely that preset 39 or 0 are tuned somewhere in the vicinity of what your modulator would produce. In that case, set the TV to preset 39 and try and tune in the modulator. Try the same for preset 0.
If that doesn't work, you'd need a suitable remote for the TV set. EDIT: It seems the presets can be tuned and stored without a remote. See https://www.p4c.philips.com/files/1/...20_dfu_eng.pdf |

Re: Philips GR1AX space helmet tv.
I might be wrong here but wasn't the GR1AX prone to going into hotel mode on it's own? This would prevent the user from entering the tuning mode and limiting the volume level.
To recover from this you needed to select the last prog number or the last but one and perform a series of button presses, or am I thinking of a different chassis. John. |

Re: Philips GR1AX space helmet tv.
Preset 38, the keys are surprisingly mentioned in the user manual I linked.

Re: Philips GR1AX space helmet tv.
Although the set has 39 channels, they are just programme presets. You'll need to open the tuning menu and scan for the modualtor's output.
It could indeed be in Hotel mode. For the GR1AX, I think you go to programme preset 38, press store and vol - (to unlock), or, press pr - and vol + (to lock and unlock). There were some sets with 3 keys on the set, others had more. YMMV. When unlocked you will be able to access the tuning. Open rhombus key on the remote control.

Re: Philips GR1AX space helmet tv.
Which is not needed since there should be a rhombus key on the local controls.

Re: Philips GR1AX space helmet tv.
The GDR11 modulator appears to cover the whole of bands IV & V, so he should be able to find a match to one of the TVs presets by trying 21-68 in turn.

Re: Philips GR1AX space helmet tv.
Afternoon all thanks for all your input it has been most helpful. I have now somehow got the tv to work, i held down the store and control's . I wonder if you know of better quality STB (used) that will work with the tv ie Humax etc. Many thanks Steve.

Re: Philips GR1AX space helmet tv.
Glad to hear you got the tuning sorted.
I don't really know what you mean by better quality STBs, the Goodmans you have is pretty decent in my experience. There aren't many with an inbuilt UHF modulator. If you want a more modern box you will have to route the signal through a VCR.

Also there are a small number of Standard Definition channels that only can be received with a DVB-T2, a so-called HD tuner.

Re: Philips GR1AX space helmet tv.
Your Goodmans GDR11 Freeview box may be suffering from dying electrolytic capacitors in the power supply. This was a very common fault - it sometimes started happening after only a couple of years' use.
Open up the box (don't forget to unplug it from the mains first!) There are some screws in the bottom. Undo these, then unclip the two halves of the plastic case. Look closely at the circuit board. The usual fault is a 470uf or 1000uF capacitor which appears to have gone dome-shaped on top. Sometimes the top looks flat like normal, but the rubber bung has pushed itself out of the bottom of the capacitor. If you spot a failed capacitor like that, replace it and it's pretty much guaranteed that your box will work perfectly again. To prolong the life of the Freeview box, I suggest only plugging it into the mains while you are actually using it, and unplug it when you're not. Don't worry about missing an over-the-air software update - these have finished now. |

Re: Philips GR1AX space helmet tv.
Afternoon, so would this fault result in lack of tv stations when rescanning?
Thanks Steve. |
