Issues with xantrex dr series inverter


Make sure the battery connection is solid, if the 12 V collapses at the inverter -> no power. If that is OK, make sure to apply first a known good load, like a light bulb, if that still causes a problem the inverter is broken :-(

The hose on my accuspray turbine Hvlp system is collapsing once it gets hot. Do hoses wear out like this, and can I replace re hose with a standard garden hose, or do I need to buy an accuspray hose?...


The hose supplied by Accuspray does soften as it warms up but should not be collapsing. Most hvlp turbine system manufacturers supply a hose with a helix reinforced hose that will not collapse.

The majority of hoses for hvlp systems are 3/4" inside diameter hose like the Accuspray hose and will work with your system.

The fittings will work with any 3/4" garden hose. Problem with using garden hose is that the cheap ones will collapse and kink and the quality ones will be heavy.

No power


try to remove the cables and battery on your laptop. Then press and hold the power button for 8secs. Then reinsert the battery and cables on your laptop. Turn on the laptop and observe if the power light is on. If it is still off, there are 2 technical issues to be resolved. One is that the circuitry on the motherboard is not repsonding, that means you need to contact your laptop provider to replace the motherboard. Another one is that the power supply of it is not responding well, again you need to contact your laptop provider for such...

Casio Privia PX-130, 8 months old: fluttering sound


If I were to venture an educated guess I would vote for failing filter caps in the power supply.

The power is likely collapsing under load of the speakers but headphones take much less drive.

If this has an external wall-wart power supply, you might try a new one IF the output is found to be under the rated voltage.

Internal power supply components are beyond those individuals that are not adept at electronics.

Turn on TV, no picture but sound is ok, thin white line running across screen


You have a frame collapse problem. Line, EHT, power supply, video and sound stages are all functioning. Check frame output ic for dry joints, resolder all pins. HT supply for output ic's derived from line stage check for open circuit safety resistors around line output transformer, if you find any then frame output ic will also be suspect. WARNING Very high voltages exist around the line stage. Make cold tests with Ohm meter with set unpluged from mains supply.

My console plays my games, but there is a full red ring? what does this mean?


OUCH! You have the red ring of death! Did you by chance have xbox on it's side for a long period of time instead of flat? If so, that's why. They say there made to do this, just like the old ps2's, It a load of ****. The laser lens circuit will need to be replaced. If you didn't have it on it's side, then you have a bad graphics chip, or cold solder joints, or the motherboard is shot.
