Unplug the inverter, and have the outlet tested. After being unplugged for a while, the inverter should reset when it is plugged into a grounded outlet.

It is most likely the low voltage alarm. Suggest connecting when the car is running with no load (110 volts not connected). If the alarm continues turn the unit off and on to reset.

Hope this helps?

Inverter Protection Features
• Short Circuit Protection. The inverter will automatically shut down until short is removed.
• Low Voltage Alarm. An alarm will sound when the voltage from the battery discharges to 10.5 +/- 0.5 volts DC. This is an indication that the battery needs to be recharged.
• Over Voltage Protection. The RED LED Indicator Light will illuminate and the inverter will automatically turn itself off when the input exceeds 16.5 +/- 1 volt DC.
• Under Voltage Protection. The RED LED Indicator Light will illuminate and the inverter will automatically turn itself off when the input is less than 10.0 +/- 0.5 volts DC.
• Overload Protection. The RED LED Indicator Light will illuminate and the inverter will automatically turn itself off when the continuous draw of the equipment being operated exceeds 1200 watts or the surge draw of the equipment exceeds 2400 watts.
• Thermal Protection. The RED LED Indicator Light will illuminate and the inverter will automatically turn itself off when the circuit temperature exceeds 150° F

Sony bravia kdl55hx729 3d led tv turns on 3 seconds shows picture than four red flashes

the error light sequence that you are seeing is indicating a "backlight error". Most likely you have a bad inverter board -the board that powers up the back-lights behind the display panel. They might be available via ebay if you are a DIYer, or you need to call for sony service.
Good Luck!

It sounds that the back-light inverter has the fault. If there is any winding short [cannot detected by measuring with an Ohmmeter], this type of fault can occur. The only thing to do is replace the back-light inverter board. The LED blinks indicates a short circuit .

Turn tv on. green light solid display, no picture or sound

The flashing green light is likely indicative of a self-test failure, indicating the TV has detected some sort of internal fault. With no picture or sound, one strong suspect is the power supply. Flat-panel TV's have an internal DC power supply that converts the inbound AC current, and when these fail, or are unable to supply a minimum level of power to the set, it can behave as you describe, providing only enough power for the green light to illuminate.

Hi Joyce,

First of all thank you for posting your question here at Fixya.
I've suspected that the fault is not the cable reception, hook up, but inside the set. To confirm it, check if the symptoms remain the same no matter what the input is (DVD/BD player, game console, direct TV, etc.). If the problem still persist, then the fault is either the inverter board or the backlight of the TV.

Backlights are the one generating the brightness backround of LCD to see the images generated at the LCD panel. It has a high voltage source that will light it up and that is the inverter board. If one of the backlights fail, it will produce overload to the high voltage transformer of the inverter board and will sensed by the feedback circuitry and will automatically shuts off the power supply of the inverter board to avoid further damaged. Same when the inverter board gone to malfunction, the feecback circuitry will automatically shut off its power supply.
The backlights and the inverter board must be checked to isolate where the fault came from. Most of the faulty backlight has a physical indication of fault like blacked end, and can be easily identify through visual inspection. If the backlights are in good condition, then the fault is the inverter board. and is a reliable supplier of parts, check your model no. at the rear panel and then search it to their search engine and all available parts will be displays.

Also, I would advice you to double check if your unit is under warranty period (1 year), if so, avail it because the manufacturer will fix it for free. Opening the rear panel will void the warranty.

Please let me know if you need further assistance.
Hope I gave you an idea what's going wrong to your unit.

Have a nice day!
Good luck and take care!
Kind Regards,

Two possibilities: the better one is that some joker put the set in demo mode (which includes a flashing power light), then turned on the Key Lock feature and turned off the set.

You have a poor or missing earth on your lights and are getting feedback. Earth with a spare piece of wire each lighting earth point to isolate. The bad earth will be shown when the fault stops by using the tempory earth wire. Remove faulty earths and clean contacts.

I have a Sony KDL-40V2500 LCD 1080P TV there is no picture the

A 4 flash shutdown indicates a backlight problem. It can be acused by a bad backlight inverter board (the backlight power supply) or by a defective backlight in the panel. There are fuses on the backlight inverter board called "picofuses" which will need to be checked in order to isolate the problem to the board or the panel. If the fuses are good, you have to replace the panel (very expensive!). If the fuses are opne, most likely the back light inverter board has failed.
