should apply to them all, and tells you what the LED blinks mean in the diagnostic LED Explanation table, in the section titled 'Serviceability Features of the System' under the expanded Technical Specifications heading.
Unfortunately you do not say whether the 'beeps' are audio/aubible beeps, or the pattern of the beeps.
I hope the table of LED blinks helps. It does not tell you what to do about the fault though ! (depends what it is)

hello i was wondering if anybody can help me out here,recently my att unverse dsl nvg510 modem redlight (wifi setup ) is flashing red and sometimes flashing green. my internet is running good, all the device that connects to wifi is good also. and also i unplug the power for few minutes and plug it back in and still that redlight keeps on flashing. nobody can answer my question. thank you

Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code. Check IC406 audio amp, PS401, and 402. On some projection models of Sony TV sets, this code means that T8005 (flyback transformer), or the associative components in the high voltage circuits are defective on the D board.

The DM module needs to be repaired. Goto www.TvRepairKits.com and get their blinking green light kit for your model.

ouch, it cost them $300 to have the chassis rebuilt, if they want that kind of money kick it to the curb.

Hi,
Symptom shows Lamp is weak in result and causing restart of TV again and again. Your TV requires new lamp as per following part number...
A1085447A* LAMP BLOCK ASSY XL-2200U
It is available in Sony Accessories Store for $200 and replacement procedure is written in instruction manual of TV.

Always buy Sony original lamp for TV and avoid aftermarket / cheap lamp for TV safety.

make sure that all of your wires are still hooked up tight and not loose.start there and see what happens.

Check your fuse at the battery. While AGU glass fuses "look" good, when you read the voltage AFTER the fuse, you can only be getting 5 volts or so. I can't tell you how many times I have seen this.

you have to much power running to the amp

Try hooking an mp3 player or some other source into the amp (in place of your car stereo)while the car is running to test it. You may have damaged the output of the radio. If not report the results here.
