KDL-40W2000 Startup Problem

Hello, I have a Sony KDL-40W2000, which from power up has an orange light and the red standby lit.When turned on, it displays a picture for 5-6secs and then shuts down. This happens half a dozen times before going into standby with the red light flashing 9 times. This is a Sony code that indicates an error of DTT Trouble (Communications / BS_CS_PROT). I've checked the voltages on the power supply board and they check out ok. The FEE board seems to be the suspect but what is your opinion?

    No, still the same, also tried hard reset initially with no joy.

  • shaun taylor Jan 26, 2014

    i know the inverter board can give this sort of problem, you could try resoldering the board!!

  • hugh55419
    hugh55419 Jan 26, 2014

    I've taken the inverter boards out (2 linked together), reoldering anything that looked suspect and powered up but still the same. When the picture comes up, albeit for a brief time it looks very clean.

  • shaun taylor Jan 26, 2014

    there's a possibility that one of the transformer on the inverter board could be causing this or even a faulty lamp/tube, you could disconnect the connectors that are connected to the inverter board one at time swtich the tv on see if stays on

  • hugh55419
    hugh55419 Jan 26, 2014

    I've disconnected each connector on the inverter boards, all with the same result except that when it goes to the red flashes there are four instead if nine.

    Also, during the above process, the orange light flashed red and a Smartlink box showed which said Stop Recording, Yes or No. At another instance, an Auto Tuning Box appeared and auto tuning started before it reset.The orange light which indicates a sleep timer which I have never used. Is this of any relevance?

  • shaun taylor Jan 27, 2014

    i'm not sure on this problem,but going back to the inverter i forgot to mention there's 3 fuses in series they look like resistor it's worth checking them,

  • hugh55419
    hugh55419 Jan 27, 2014

    Hi Shaun, checked those 3 fuses and they are all good. I feel this is a processing problem (going back to the code 9 fault) and I'm only going sort this out by board substitution. Just got to decide which ones. I'm back in the UK this week so I'll try to locate a FEE and a BE (main processor) board and see how it goes. As all the boards are interconnected, I presume that anyone of them could cause this problem.

  • shaun taylor Jan 27, 2014

    i don't think it's a main board fault as you have graphics, i hope i'm very wrong but it could be panel fault, let me now the out come good luck

    Just to update this thread, I obtained a cheap FEE board from ebay and this immediately fixed the problem.

Hi I ve a sony KDL-40W2000 stuck on stdby red light flashing 4 times the stop for 3 second ??any advice please

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. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience. If blinks continue without any pause, the main board is faulty.

My Sony Bravia KDL-26S3000 won't turn on and is stuck in standby.

Hi,

There is a power fault with one of the PCB's inside, contact Sony if you are still in warranty, if not contact a Sony service center as it will need an engineer to open it up to repair it.

Thanks
