I have a 9000 hd spider coming up for 2 yrs old.
The channels work but on hd they are all strobing slomo and on sd channels you get a pixelated screen which to me is pointing at failing tuner.
Is there any way to boost /extend the life of this unit .
Any help advice appreciated.
cheers chronoman

Select a HD FTA channel (pref on 28.2e) and press info twice quickly that way you can read the S and Q levels. It could be a slight dish alignment problem and not the tuner.

This iisnt my box but a friends,I first thought was a sat issue and he got engineer out and all ok. another box is good in his house and fault replicated in my house

heres ratings,my box work perfect of this but this box is strobing

If you are happy to do so check the power supply voltages with a multimeter BUT be warned quite high voltages in that area can give you a nasty jolt. Look for signs of capacitor leakage such as bulging cans, and white deposit on the PCB any showing these signs must be replaced and for a few pence more get replacements rated at 105C as they last longer.

i have a combo unit i could use that psu on the board .
will take board pic with decent res and post
cheers for help

photo3.JPGphoto2.JPGphoto1.JPGoh well too much to hope for same psu. will get a unit to test in day or 2.
heres some pics ,i cant see any obvious

Good pictures but cant really see anything obvious, if your thinking of trying a supply from another receiver be careful as there were some changes in production. Make sure the supplies are identical.
WARNING under certain failure conditions the main capacitor (the biggest on the board which should be rated at ~400v) can store a high voltage for a long period of time, so be careful when removing the power supply from the receiver (I've been caught like that).

well not power supply.
stuck now.
Would a tv engineer be able to diag one of these?

It is still possible that the power supply is the culprit, sometimes only a close visual inspection will show if one (or more) capacitors need changing. A test with a voltmeter would show if any one of the voltages are low or a test using an oscilloscope would show if there was excessive "ripple" on any lines.
Sorry to say from the pictures it's not possible to say but I would still try the power supply as it's the most likely culprit.
Yes a TV engineer should be able to measure the power supply voltages or you can buy nowadays very cheap digital multimeters (about £3~4 on Ebay) which would be quite adequate for this job.
Note the correct voltages are printed on the PCB next to the flexible cable which links the PSU to the main board, but again if you do this yourself do be careful as a slip with a probe could be an expensive repair.
Have you contacted the importer to ask if they can repair it for you? might be a good idea.
My Spiderbox 9000 combo is now about 20 months old and working perfectly so you have my sympathy that yours is playing up.
One point do you have plenty of ventilation around the Spiderbox? it's not unusual to see plies of CD's or DVD's or even a nice vase of flowers blocking the ventilation slots on top of the receiver.
