20 Most Recent Sony BRAVIA KDL-40V3000 Television - Page 7 Questions & Answers

If your Sony came with a CD or DVD, you may need to install special drivers so your PC can find the set.
If it didn't, you may have to select the external VGA output on your laptop to activate it; not all laptops have that output turned on by default.

First try a hard reset

TURN OFF... UNPLUG and leave overnight or several hours. reconnect and try to turn it on. If still faulty it will require technical intervention. This is not DIY repairs as it requires specialized knowledge of circuitry and tools. Unlike PC's these units have low tolerance to board swap jockey tactics and will end up costing you 3 times the value of a service technicial repair if you attempt it.

Please rate my help++++Thanks for using FIXYA

you might get lucky and be just a bad connection on your LVDS cable but it sounds like a bad lcd panell big bucks

Chances are it is the T-CON Board that is on the LCD Panel. Problem is , you can only get the T-CON board when you replace the LCD Panel. The Cost would be more than the unit cost to buy new.
I hope this helps,

Please recheck Lamp Cover and make sure it is fixed in its space securely as 3 times red blink shows lamp cover error.
There is small safety switch in TV cabinet under lamp cover that has to be pushed by lamp cover if it is fixed in its position properly. That switch is not being pressed by lamp cover and causing this error.
Thanks.

If you cannot select a HDMI input then it is not sensing that a HDMI signal is present. Be sure the HDMI cable is not bad and the source is working. If it is then you would probably need a Signal Board. To be sure, a Sony Service facility should check it out. Sony Customer Service Number is 1800-222-SONY.
Hope this helps

Hi,

This is a fault with the panel or one of the surrounding boards, you need to contact a Sony service center as there is no easy solution.

Just to warn you, it will be costly....!

Thanks

Follow these steps and check if help to resolve the issue:

1. Disconnect all the attached external device (if any) and then try turning ON the TV.

2. Remove the surge protector or power strap (in any), directly connect the TV to a working Power outlet and check.

3. Try changing the power cable (if possible).

4. If the issue persists then Service may require to resolve it.


Good Luck!!!!!!!!!!!!!!!!!

go into menu of tv find autoprogram activate it-dont do anything til its done programing itself--

Shutdown with a 3x blink pattern occurs if the 12v from the power supply (GF1 or GF2 depending on model) is lost at CN6153/pin 6 to the AU Board Q1224 to Sub Micro IC1205. The suspects, in order of likelihood, are (1) Power supply and (2) the AU board.

Your pannel has damage by the hit, the only way is to replace the pannel. It is costly if you are in OOW. If it is still in warranty, call service right away and claim for an replacement.

UNPLUG AND TAKE OFF THE BACK AND CHECK THE FUSES,,MGT BE BLOWN,,

Standard blinking codes for Bravia sets for US only goes to 10 blinks which points to faulty or short circuited components inside whereas the Australian range of KDL's goes to 13 blinks of the LED which points to a faulty balancer and must be taken into a service department.

Try leaving the TV unpugged for 30 minutes so the TV can reset itself.
If that doesn't work, most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you flashing red light codes, circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.

This type of failure is not common. You indicate that the set is slightly over a year old. As a first step, I would attempt to request a warranty repair from Sony. If the set is close to the 1 year limit, it may be a bit of a fight, but you may get this repaired under warranty. Realize that you will need to speak to a manager, not the initial rep on the phone. Have a copy of your purchase receipt with the purchase date. Now to the probable problem. In all likelyhood, a capacitor has failed in the power supply section. Depending upon its function within the circuit, it is possible that it caused the smoke. Until you have a final resolution with Sony, DO NOT open up the unit. Once you do, any possibility of warranty service is voided. Please update this with any progress you make with Sony and we'll continue from there. Dan

i have the same problem on mine, my tv is only just 12 months old, in the last 4 weeks it had 2 new blocks put in as the tv was blue, it costing £700 each (under guarante for 3 years thank god) then lastnight the tv made a big bang then switched it self off and the sand by botton is now flashing red then green, i have to leave it 30 mins before i switch it on again then only last 10 mins before it does the same thing again, got sony coming out again to day to fix it, had it with this tv now hate it !!!!!
