Sony Wega KV-XF21M83 21" Color TV red LED flashing two times

U have a soldering iron,desoldering pump or a roll of desoldering braids,a roll of solders?Can u do basic soldering and uderstand basic electronic?FBT- the flyback transformer,the big black block of a plastic with a red wire with a cap hook to a CRT-tv picture tube.Near the big block of a plastic with a red wire with a cap hook to a CRT picture tube.Inside to the right of the FBT,there are 2 power supply ICS,those 2 ICS are dead.Replaced these 2 power supply ICS near the FBT,will solved this tv LED power light indication blinking and will have stable tv power again,and tv will work.

the flashes are a indication of the actual problem. 5 flashes along with a popping sound is the flyback transformer failing to provide the high voltage necessary to reproduce the image on the screen.

The LED used in most tv are dual color led,some have two lead, some have three. try to find the same size and replace it.

The 5 blinks indicates a White Balance Failure. This involves checking voltages and components tied directly to the CRT. I would not suggest any attempt for self repair. The cost for this repair should not be significant. Figure a parts cost in the $30-$50 range at worst.

The high voltage power supply is going bad on both units.. Pretty soon, it won't power up at all. For a fact.
Don't try to replace the power supplies, TV's are too cheap.

How many times does the timer light flash between pauses?

Check 470 uF 450 V in the power supply. I don't know if the chassis is the AE-5, but I had a similar case and the capacitor was bad.

Please tell me if it worked.

When it shuts off. Try doing what's called a self-diagnostic test.
As soon as the television shuts try these steps.

Pressing on the front panel's ?INPUT? and ?MENU? buttons at the same time, and holding for 5 seconds,
activates the Self Diagnostic Code Mode. The LED flashes denoting a two digit Error Code, or indicating no problem
has occured since the last Initalization.

Please do Note: The front panel buttons must be used, NOT those on the Remote Control.

? The number of flashes indicates the value of the MSD (tens digit) of the Error Code.
? The flashing then pauses for approximately 1/2 second.
? The LED then flashes indicating the value of the LSD (ones digit) of the Error Code.
? The Error Code is repeated a total of 5 times.
Example: If the Error Code is ?24?, the LED will flash two times, pause, and then flash four
times.

The Error Code designations indicating a malfunction, or no malfunction, are listed below:
Self Diagnosic Code Description
1 - 2 = no error detected
2 - 1 = X-ray protect (high voltage or beam current)
2 - 2 = Short protect (short protect monitors low voltage supplies)
2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection)
2 - 4 = Vertical protect (usually loss of vertical from the source).

I read the manual and it says in the FAQ.
Q- TV doesn’t turn on
after disconnecting
the TV and timer
LED flashes

❏ Press the POWER button on your remote control or in the TV front
panel, one more time.


Tell me if it works...

This is due to problem in deflection area and power supply section malfunction. Make one general service by technical person immediately to avoid major transformer failure problem. Since this is initial stage, the cost of repair is probably less.
