Question about Sony KV-36XBR400 36" TV

1 Answer

T V Shuts off by itself, after a couple of minutes.

I have a Sony Triniton 36" TV model # KV-36XBR400, Manufactur date November 2000. The TV has a great picture and the sound quality is great, but some days it will work fine, but then other days it will shut itself off after a couple of minutes. You turn it back on and the same thing it will play then shut down again after a couple of minutes.

    KV-36XBR400 shuts down, four blinks on front led.  Had to lug unit to Aut. Sony Repairman.  Said it was a "D" board problem.  He sent for a Refurb. unit from Sony.  Installed refurbished D board from Sony.  Brought it home, plugged it in, noticed picute was fuzzy and within two hours, TV went out again.  Received 4 blinks on LED on front of TV.  Unplugged unit to reset, then turned it on again.  But within a day, it went out completely with the same 4 blinks on the front LED.  Called Sony Repairman, brought it back to his shop and this time--he said he was done with the unit.  He refunded my 439.00 dollars, and I now have a 240 lb paperweight.
    Reviewed various posting of "fix its" and have not read any with my problem.  Perhaps you have a solution.  Love this TV, and it cost $2600.00 new and is HD ready.

We have 7 blinks on my KV-36HS420 Sony Wega Triniton. It will come on with only 5 seconds of audio and then shuts itself off with 7 blinks. What part does it sound like needs to be replaces


The power supply in all likelihood. Not something you can do. Any tv repair can take care of it but will likely charge $25-30 for an estimate. They have to spend a bit of their time to check it out. The cost of the estimate will go towards any repairs.

My sony has started turning itself off after 20-30 minutes, each time you turn it back on it will turn itself off after a shorter and shorter run time. Leave it over night and it will start the next day...


It might be over heating. If there is a lot of dust
inside of the back of the T.V. you should take it outside and blow it out with an air compressor.

good luck

Sony kv 36xbr400 - Won't stay on


Problem is in the secondary power supply which provides power to high-voltage and scanning sections of main board. This is called BOARD D, and has the high-voltage section, flyback transformer, and control IC on it.

Can't be fixed by user, needs service tech and new part, around $300

Sony KV-36xb1400 convergance Problem


Its not matter of service code only. You also need service data to fix it. But question is, how data is being corrupted? It seems hardware failure in your TV set.

TV will not stay on for longer than 5 minutes


This sounds like the shutdown circuit is shutting down the TV due to an over current condition. This overcurrent condition is caused by a component in the HV section drawing excessive current. the 5 blinks is a visual indication of the problem.
