Sharp aquos model# lc-60e831u screen is not lite up and light flashing one long and one short


Those 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.

Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board

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.

Avision AV8350??? the error led is on, first time the led on & off For 8 number Sequence. then on for ever.


Hello,

When you first turn the scanner back on, the READY light will blink, indicating that the diagnostics are in progress. If the Ready LED and Paper Jam LED blink 8 times, the error indication is "Light Check Fail (ADF)" or "Flatbed /ADF inverter check error".

Followings are the solution for the above problem:

1. Lamp is on? Yes. CCD error, Optical assembly is to be replaced.
2. Lamp is on? No. Flatbed or ADF Inverter error. Lamp inverter circuit is to be replaced.
3. Lamp is on? Yes. Issue resolved.
4. If the Lamp is still off, then Lamp is to be replaced.
5. If the issue still persists, then you may have to contact the authorized Avision Service personnel for further diagnosis and suggested repair or replacement.

Hope the above information is helpful.

Please revert if you have any doubt.

Thank you for contacting FixYa.

Standby LED blinks 4 times


Hi there,

4 blinks on a Sony Bravia indicates a backlight/inverter (aka ballast) problem. These ballasts are regrettably only available with an entire LCD panel. :( You may perchance be able to find a parts outfitter online that scraps out TVs and have a used ballast.

Typical backlight problem on an LCD shows up as the screen lighting up for a second or two and going back off. The 4 blinks just confirms your problem.

You need to check the blinking times of the Paer jam LED. Then check the followings:
1. If the lamp is on, then ADF Switch is malfunctioning. Disble or short the switch.
2. If the lamp is off, then it is Flatbed or ADF Inverter error. Lamp inverter circuit is to be replaced.
5. If the Lamp is still off, then Lamp is to be replaced.
6. If the issue still persists, then you may have to contact the authorized Avision Service personnel for further diagnosis and suggested repair or replacement.
Hope the above information is helpful.
