SOURCE: Standby LED blinks 4 times

Hi there,

4 blinks on a Sony Bravia indicates a backlight/inverter (aka ballast) problem. These ballasts are regrettably only available with an entire LCD panel. :( You may perchance be able to find a parts outfitter online that scraps out TVs and have a used ballast.

Typical backlight problem on an LCD shows up as the screen lighting up for a second or two and going back off. The 4 blinks just confirms your problem.

SOURCE: Set will not power on.. Blinks red LED 8 times

It's a power supply related problem.
The flashing 8 times is a trouble code. A Service Manual for your TV model will have the info on the codes. It could be a bad capacitor or a transformer on the power supply board.If you have some electronic experience, you can find a Service Manual for your TV over the internet. Cost about under $20.

SOURCE: Blinking power and opc leds on front of unit

From the information you have provided failed capacitors in the power supply is likely causing the problem. The safety circuitry shuts the TV set down when it detects a problem. This model of TV has over 2,000 parts which include millions of transistors inside the integrated circuits. The capacitors will change value, leak and become defective. Resistors will change value and burn. Integrated circuits and transistors can go bad. This can cause other components to become defective, which can have a domino effect and cause other parts to fail. Replacing one defective part may make the TV operate for a short time but the part will fail again since if the parts that caused the failure to begin with are not replaced. The only way to know for sure what is causing the problem, which parts that are no longer within factory specs and for proper repair all the electronics must be diagnosed by someone with the correct electronic test equipment and the skills to use the test equipment. The repair should cost about $250 if carried into a TV repair shop. A small TV repair shop will often charge less than a large repair facility.

My Sony KDS-60A3000 randomly turns off, then the red "Power LED" blinks three times repeatedly (not "Lamp LED"). We turn it back on, the process repeats again between 20-60 minutes.


3 blinks of Standby/power LED of Sony sets denotes a SMPS board [G-board] failure. . 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.

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

My polaroid tv has a v-chip i need to how fix it. i need a code


Hello

If your device does not respond to the remote after trying all codes listed for your brand, or if your brand is not listed, try

searching for your code:

1. Press a device key once.

2. Press and hold SET until the red LED blinks twice; then release.

3. Enter 9-9-1, then the device group number (0= Cable, 1= TV, 2= VCR, 3= Audio). The LED blinks twice.

4. Aim the remote at the device and press Power. The remote sends IR codes from its library to the selected device,

starting with the most popular code first. If the device responds, go to step 7.

5. If the device does not respond, press CH+. The remote will try the next code. Continue until the device responds.

Note: Press CH- to try the previous code.

6. To search for other device codes, repeat steps 1 to 5.
7. Press SET to save and exit.

If you have set up the remote using the procedure in "Searching for Your Code", you may need to find out which four-digit

code is operating your equipment.

For example, to find out which code is assigned to your TV:
1. Press TV once.

2. Press and hold SET until the red LED blinks twice; then release.

3. Enter 9-9-0. The LED blinks twice.

4. To view the code for the first digit, press 1. Count the LED blinks (for example, three blinks = 3), and write down

the number in the appropriate code listing in step 8 under "Programming a Device".

NOTE: If a code digit is 0, the LED does not blink.

5. Repeat step 4 for the four remaining digits, using 2 for the second digit, 3 for the third digit, 4 for the fourth digit,

and 5 for the fifth digit.
6. To check for other device codes, repeat steps 1-5, substituting the device key for TV

Power will not come on even after system reset. Pushed reset and LED flashes then after it stops flashing TV will still not turn on.


do self check: when it shuts off and power light goes off:

On front of set press and hold both menu and input (device) buttons for at least five seconds and release both buttons.

Power light will blink a two digit error code, like 2 blinks, 2 blinks, a pause and repeat it several times.

Let me know what error code and I will assist you
