Error light My TV won't come on and the LED flashes 7 times. What error code is this? Would thid be worth calling a technician to fix or hauling it off to the store?

The red light flashing is indicating the error.
depending on the make and model of the TV, the duration of the flash and number of flashes determines the error code.

can you please mention your tv model

power will not come on Linda, could be bad capacitors or cracked/bad solder joint,bad main logic board.
Check the attached links,instruction and guides, Good luck

Sony Bravia TV kdl red blinking led light error codes solutions

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 stage 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, to many popular brand TVs and other devices. Viewing it in "Mosaic" will make surf easy.

I have the same problem, called sony up but they are not responding back. The tv is still under warranty and brought it from Amazon. My situation is same but my led error code is 4 or 5 flashes. Does any one knows what's wrong with it.?

Hi,
Flashes of your led light indicates an error code. This is usually caused by leaky filter electrolytic capacitor. This will affect the regulation of the supply and sometimes needs a little warm-up to function normally. This faulty capacitor is in the regulator section/low voltage power supply. The symptom will get worst if not isolated.
This is not DIY. I've advice you to send it to repair shop or look for a qualified technician to fix the problem.
Hope it may help you!

Have a nice day.

if you have the circuit diagram of your tv,check the horizontal polarisation IC closer to the line transformer and replace it.If it doesn't work,send the question again.

This is from my WS65907 service manual.

4. Self Diagnostics
The “Power ON LED” provides an indication of the sets operation, and the possible cause of a malfunction.
1. Initial Control Circuitry Check
Immediately after the TV is connected to an AC power source:
• The LED flashes three times ... indicating the Microprocessor has initialized and is functioning
properly.
• If the LED does not flash ... the Microprocessor is NOT functioning.
2. Error Code Operational Check
Pressing the front panel “INPUT” and “MENU” buttons at the same time, and holding for 5 seconds,
activates the Error Code Mode. The LED flashes denoting a two digit Error Code, or indicating no problem
has occured since the last Initalization.
Note: The front panel buttons must 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: For Error Code is “24”, the LED will flash 2 times, pause, and then flash 4 times.
3. Error Codes
The Error Code designations indicating a malfunction, or no malfunction, are listed below:
“12” ... indicates no error has occured.
“21” ... X-Ray Protect circuit.
“22” ... Short Protect circuit.
“23” ... Horizontal Deflection failure.
“24” ... Vertical Deflection failure.5. Circuit Adjustment Mode
Most of the adjustments can only be performed using the remote hand unit. Many of the adjustments must
be performed in both the NTSC and HD modes. Video/Color adjustments must be performed in the NTSC
and HD modes, and data must be preset in the 480P (DVD) and VGA modes.

Five buck solution; If you have any tek skills at all and are feeling adventurous; UNPLUG THE POWER, remove the back panel; You will be faced with the mainboard. In the lower right quadrant you will see two small capacitors, like tiny yellowish coke cans. If these are bulging, there lies your problem. These must be replaced. If you have no soldering skills, take only the mainboard to a fixit shop and have them solder in the two capacitors easily found on line. No guarantee's but worth a try

the status light blinking red means a fan (the unit hs 4 of them) has failed. you need to determine which one. use the self diagnostic function:
Error Code Operational Check
Note: The TV must be in “Shut Down” and not manually switched Off, to perform the Error Code Operational
Check. When the TV is switched Off, the code automatically resets to “12” No Error.
Press the front panel “DEVICE” and “MENU” buttons at the same time, and hold for 5 seconds to
activate the Error Code Operational Check. The LED will then flash denoting a two digit Code.
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.
Example: If the Error Code is “32”, the LED will flash three times, pause, and then flash two times.
• The Error Code is repeated a total of 5 times.


and read the code.
35= Chassis Fan failure
36 =Exhaust (Back Cover) or Lamp Ballast Fan failure
37= Engine (DMD or Lamp) Fan failure
