Question about Sony KV-36FS17 36" TV

1 Answer

Led light blinks even when TV is off.

My TV is 5 years old. For the last week and and a half, the Led light is flashing. It flashes 5 times, stops for a few seconds, and then flashes again. This is happening all the time, even when the TV is shut off. We don't use the remote that came with the TV, we use our Cablevision remote. However, I was dusting the remote control holder, so I took them out and put them on the couch. Does anyone know of a button on the remote that could have been accidently hit? If not, so far the TV is working fine still, but does the led flashing mean something is wrong? Thank for any help, Marie.

I have a sony tv model kv-27v42 i have sound but no pictture and stand by light blinks what is the problem

How many times do this standby light blinks at a time of switch on? These blinks are fault indications. From the number of these blinks, you can get an idea about the faulty circuit section inside it. Count it. If you wish to get more details about the blinking codes to Sony TVs, check this link.

5 blinks - check the 5v SOS D Board since the set is a plasma.

Your best best is to obtain a quote from an authorised Panasonic service centre on the likely cost to replace that board if required, then you can make a decision afterwards - to either go ahead with the repair, or cut your losses and purchase a new set if the latter option turns out to be cheaper.

Always ask about and insist on extended warranties whenever you buy a new TV such as plasmas. These will cover you against expensive repairs, and having to buy a new one each time the old one breaks down in the future.

These days manufacturers lean toward board replacement in plasma and LCD TVs rather than individual components, as it is quicker and easier to replace a whole board than to try and fix an old faulty one. It's also tidier in terms of layout.

Sony Wega Kv-36XBR250 screen blinking

I have seen this flashing before, this could be an indication that the picture tube is weak, what happens is that if the white balance is off there is a circuit called akb it monitors the kathode of each gun and if they are not in balance it will attempt to balance it out. if it can't the picture will begin to flash, sometimes in some models the power light will blink 5 times. On some models the power light will only flash if the tv gives up trying to compinsate for white balance and shuts off compeletely. If you see the tv shutting off with 5 blinks then you know for sure it is time for a new set.

I have a 36" TV that won't work - Red LED light blinks 5 times

The 5 blinks indicates a White Balance Failure. This involves checking voltages and components tied directly to the CRT. I would not suggest any attempt for self repair. The cost for this repair should not be significant. Figure a parts cost in the $30-$50 range at worst.

The TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.

If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

5 LED flashes is a CRT drive problem (IKR) CRT is poorly set G2 volts wrong or the CRT is exuasted. Either way you need an engineer and an estimate on the cost of repair.

Sound, but no picture. Standby light blinking 5 times

A few weeks ago my set started flashing to a black screen. Now a couple of weeks later, i have no picture, but the set turns on and i have sound. The standby light is flashing. I purchased the set in 2000 so it is seven years old. This is the first problem. Could it be all three of the bulbs? Could it be all three of the bulbs? no as you say that sound is ok that means your power supply &high voltage section is ok. please check chroma ic luminance section or system control section stand by ckt ihanks

Color variation and blinking red light on bottom of tv

The light flashing 5 times is normal at turn on as the set is monitoring current drain on the pictures tube cathodes. Any speakers near the set that have un-shielded magnets could possibly cause color issues.
