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 .

SOURCE: Sony KDL-46s2010 4 red light blinks

I would suspect one or more of the miniature flourescent backlight lamps. One way to confirm this would be to power up the set with a grayscale image at 40 to 60 IRE. If one or more lamps is failing to light, a slightly darker horizontal area in the grayscale will give it away. Unfortunately, Sony will not supply any of the backlight components apart from a new LCD panel. Sorry.

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.

Klv32s310A sony bravia gets start on with green light and after a second turns to stand by mode blinking the red light 6 times after each 2 second interval


Hello Sagar,
green led means tv powered on and status ok.
Red blinking light almost always means defect, overcurrent or overload.
6 blinks for Sony lcd flat tv means trouble in backlight circuit, or backlight inverter (backlight illumination or lighting makes your tv screen visible).
common problems in the inverter circuit, which drives the backlight, or shorted drivers, or short-circuit transformers or open circuits.
You should find the problem in the inverter circuit, or in the power supply board or in the main board.
Also look for bad capacitors (electrolytic caps) which are bulged and swollen on top.
Decoupling plugs from printed circuit boards can help you in finding the problem board by elimination method.
If you power up the set after unplugging certain plugs on f.e. the inverter board , this could result in getting a green power led and concluding that this board is faulty.

succes,
Walter from Antwerp, Belgium.

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


Hello,
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!

I have a hitachi 55pma550 plasma tv.when I turn on the main switch red light comes on standby. But when I turn on tv the red red light on stand by turns green only for 10 seconds and goes red no picture...


It's most likely the smps. You'll first need to check voltages at CN63, pin #1-(+5v), 3-(+3.3v) and pin 8-(+6v) Also check CNPPS, pin 1-(+30v), 4-(+5v), 8-(+12v), 12-(+10v) absent these values and the power supply is clearly the problem.

I have two monitors. One Samsung SyncMaster 2233 an one Samsung SyncMaster 2243. My problem is that the SyncMaster 2233 for some reason is totally black. I'm usually not terrible with these things, but my...


hello Gabriel

Could you check your SyncMaster 2233 for me and tell me your findings. If this monitor is connected from your computer and when both switch on, did the led indication lamp from your monitor lit steady green? or this lead indication lamp lit green then turns red?

1. If the led indication lamp lit steady green then there is nothing wrong with the settings, configurations, driver or hardware on your computer. The problem would be the backlight inverter lamp in your monitor is busted. Or it could be the inverter board that supplies high voltage for the backlight inverter lamp that is bad. You can replace the backlight inverter lamp located at the upper and lower part of the monitor with a replacement part you can purchase at shoppejimmy.com. Inverter board repair can be risky if you don't have the skill. Even opening the back cover of your monitor and replace by yourself the inverter lamp is risky too, could inflict more damage. you can bring it to a local professional service man.

2. If the led indication lamp lit green then turns red, then if not the video card the power supply section from your monitor is bad, you can replace polarized capacitor with same value. Just inspect and those with blown or leaking capacitor. You can also check the terminals and solder joints for the 15-pin vga terminal connector where vga cable is connected on your monitor. Resolder the terminals.

3. If the red indication lamp did not lit at all. Power supply section in the monitor is bad. You can check the output voltage from the power supply section. +5VDC is supplied for the main board and +24VDC is for the inverter board. Replace leaking or blown capacitor with same value.

Just remember, this should be done when computer and monitor is turn off
Post back if you have more questions. I am willing to give you assistance.

Red light blinking, tv doesn't start


Your TV is in Protection Mode right now. A part inside the TV has failed and the TV will not turn ON to prevent other parts from being damaged. The red light blinking is an error code for diagnosing the problem part on the one of the power supply boards. The problem boards that need to be looked at is the Backlight Inverter Board or the Main Power Supply Board.
There is a slim chance you can leave the TV unplugged for an hour so the TV can discharge and reset itself. But other than that, I would use the warranty if possible. The TV repair shop maybe expensive, so get some price quotes to see if it worth the trouble.
