The blinking light means almost 100% that the high voltage circuit has failed. Probably need a new horizontal output transistor and flyback. Perhaps an associated resistor or diode. If you have the expertise go for it, otherwise take it to a professional. In any case be extremely careful and safe. Good luck.

SOURCE: Power LED blinks red

it is a bad fan. it also could be a power supply. Quite often the real problem is dirt clogging up the fan(s) to the point that they need to be replaced. Operation of the set in a dirty environment is not a good idea

Hello,For model KV-40XBR800,

Pls check following area.

Low HV Shutdown:
On the D Board.

My sony 21 kv21da55 no power on blinks red lights 10 times or more times pressing the channels botton repeatedly powers it on


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.
Schematics too are given.

What is the code for a One for All urc-7710 remote control for an ACER tv?


Hello,

I found the manual online for the URC-7710, but i do not see a code for an Acer TV.

Try a code search by following these steps:

1. Turn on TV.
2. Hold down the Magic button, the red light will blink once then twice, release the Magic button.
3. Press 991, the red light will blink twice.
4. Press power button once.
5. Aim remote at TV and press the Channel Up button repeatedly (up to 150 times) until TV turns off. Note: if you skipped the code that turned the TV off you can go back by pressing the Channel Down button once.
6. Press the Magic button to store the code for your TV set.

Well, I hope this will help.
Cheers!

Lost owners manual


Hello,

I do not believe this is available on-line, but have some info that might help you use the remote.

To Search For A Code:
  1. Manually turn on device to be controlled.
  2. Press and hold the "Code Search" button until the red indicator light stays on, then release it.
  3. Press and quickly release the desired ode button (TV, VCR, etc.). The red indicator light should blink once.
  4. Press the "Channel Up" button repeatedly (up to 300 times) until the device to be controlled changes channel. The red indicator light should blink off with each button press. If you accidentally overshoot the required code, press the "Channel Down" button to backtrack through the library until the device changes channel. Pressing "Channel Up" changes direction again.
  5. Press and release "Mute" button to install the code.
To Identify The Code That Was Found:
  1. Press and hold the "Code Search" button until the red indicator stays on. Release the "Code Search" button.
  2. Press and release the desired mode button (TV, VCR, etc.). The red indicator light blinks and then stays on.
  3. Press and release the "Code Search" button. The red indicator light goes off.
  4. To find the first digit for the code stored under the mode key pressed in "Step 2" press each numeric key from 1-9 in turn. When the red indicator light blinks off, the number you pressed is the first digit for the code you are searching for.
  5. To find the second digit, repeat "Step 4," this time when the red indicator light blinks off, this is the second digit in your number.
  6. Repeat again for the third digit in your code number.
I hope this helps out,

Chris
