Hi,

This is usually suggestive of ' hardware failure '.It could be a faulty power supply board ( in most of the cases ).If you wish to repair the TV, revert with make and model of the TV and i would be able to tell you few pointers to repair it,

Note - You need to have electronics repair experience , should know how to read schematics.You need to use multimeter and soldering iron ( if required ).


Let me know,if you wanted to repair it so that i could guide you.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

    Blinking red light shows internal problem with back light inverter board that seems got problem for some reason.
    Visual check is necessary to measure supplied voltage to back light board from power supply board. Local tv repair shop will do the job for you if you do not have electronics knowledge/ experience.
    Required back light board is available with Shop Jimmy, click the link to have price info.

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.

I got a Sylvania 32 inch came home From vacation LC320SLX .I try to turn it on the green light power light blink of an on for 5 seconds and goes back all to red. when you turn it on again green light...


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. Viewing it in "Mosaic" or "Magazine" will make surf easy.

Blinking codes details to many popular brand TVs are given. Surf the site with patience. Do a search by type in the brand name of the device to the search box.

Monitor won't turn on after a few hours of being shut off


If it EVER works, then the problem is not a failed part, but a weak part. The most likely component type to give you such problems are capacitors. But very few repair techs know how to find such problems, and even fewer have the equipment needed to find the bad one(s) in-circuit. The failure mode is high ESR (ESR means Equivalent Series Resistance). The lower the ESR, the better. Capacitors with high ESR cannot stabilize circuits which demand high pulse currents, such as in switch mode power supplies.

Red/green lights both blink and tv will on turn on


Are the red and green lights blinking at the same rate or not? If the green light is blinking every 3 seconds and the red light is blinking every 1/2 second, the lamp door is not properly secured. If both lights are blinking at 1 second intervals, try replacing the lamp. If a new lamp doesn't solve the problem, the TV needs service.

I hope this helps.

Laptop crashes shortly after boot, power light rapidly blinks red.


Its late, so just to make sure I'm not brain-dead basically your laptop runs fine as long as its powered by the AC adaptor but dies fairly quickly while running via battery. This is very typical of a battery that will no longer hold a charge, not normally a user repairable item. It could also be that the charging electronics (in the laptop) isn't charging the battery, again not a typical user repair job. About your only option short of taking it to the repair shop is buying or borrowing a battery as a test.
