Seven blinks - High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.
You must have through knowledge in electronics to proceed. This is a very skilled wor. You must have all measuring instruments, and ability to follow its schematic diagram.

    Thank for a solution! But Wow is that so? what a bummer, would you know any links that would guide me? or is this something im better of getting an actual professional to handle?

    Surely,
    There is a link, that will do help you to know about what to do how this problem can be solved. All details are described there. But, Fixya had prevented me providing that link to anybody, by a notice send to me yesterday. You just ask them by clicking 'contact' option by Fixya site, and give me permission to send that link name to you. Without their permission, I can't.

SOURCE: SONY WEGA KV-36HS420 will not come on

The blinking is an indication that the set detected a problem. The code usually indicates a bad regulator circuit. If yu can solder, you can probably fix this your self. Please let me know if you wish to attempt the repair. If not, expect a parts cost in the $25-$40 range plus the local labor rate for the repair.

SOURCE: Sony Wega 40" TV will not turn on, standby light blinks 6 times repeatedly

Hello,For model KV-40XBR800,

Pls check following area.

Low HV Shutdown:
On the D Board.
Check IC8004/pin 7 should be 7.4v.
Check IC8006/pin 2 should be 2.5v if lower will trigger shutdown by causing pin 1 to turn on.
Check IC8006/pin 3 reference voltage 2.2v.
IC8006/pin 1 normally at 0v. If high
turns D5007 ON which turns the latch circuit Q6532,
Q6530, and Q6527 ON and turns the AC relay RY6501 OFF.

And NOTE: 6 blinks also can be Low B+ protection.

Unregulated 7.5 v from the power supply to 5v reg IC504 on the A Board. 5v to M Board Q2314

to CPU IC2300/pin 43. If 5v missing set will shutdown with 6 blinks.

Good Luck

SOURCE: sony trinitron xbr red diagonal lines appears then screen turns

In cannot remember if this model of set uses on the CRT drive board a drive IC for the CRT colour channels, or if it uses descrete transistors. I have had component failure on this board that causes your description. The failure in your case would be with the red channel drive. Most of the time I had the semiconductors fail, and some of the support components.

Most of the time, a failure on this board is caused by some intermittant internal arching inside of the CRT. If this happens, the CRT is starting go defective.

Another cause of this fault is that the CRT is starting to go internaly shorted between the control grid and screen grid. As it heats up, the shorting becomes lower in resistance, and thus causes the pricture to go brighter until the protection turns it off. This would be with the red electron-gun.

With any failure with the CRT, the set is not worth to fix even if you can find a CRT for it.

My tv wont turn on by power button or remote. white light keep blinking.

How many times this standby/power light blinks at one time switch ON? Count it carefully. These blinks are fault indication, and known as blinking codes. From the number of blinks occur at one time switch ON; you can get an idea about the faulty circuit stage inside the TV. This will make repair easy. For more information, check the link http://electronicshelponline.blogspot.com/. If the blinks continues, and non-stop, the fault should be with its main system control IC, and with the memory IC.

How do i key in code for digibox

TO PROGRAM THE remote USING THE 3 DIGIT CODE:
1. Turn on the TV receiver
2. Press TV on the Sky Remote Control
3. Hold down SELECT and the RED buttons together for approximately two seconds, until the RED LED on the Sky remote blinks twice.
4. Enter three digit code from list for the receiver (early versions now flash twice).
5. Press select to enter code structure (the LED will flash twice if a valid code has been entered).
6. Now press the STDBY button and test other functions.
Repeat if necessary until a code is found that works most common functions.
TO PROGRAM THE remote USING THE 4 DIGIT CODE:
1. Turn your TV on.
2. Press tv on your Sky remote control.
3. Hold down select and the red button together for about two seconds, until the red light on the Sky remote control blinks twice.
4. Press tv on your Sky remote control again.
5. Key in the four digit code for your brand of TV. The light on the Sky remote control blinks twice. If the light blinks once only, recheck the code for your brand of TV and start again at Step 1.
6. Press the standby button on your Sky remote control. If your TV switches off, press select. The light on the Sky remote control blinks twice (code stored). If your TV does not switch off, press tv, then press the standby button. Repeat this (press tv, then standby) until your TV turns off, then press select (stores code).
If at this point the LED on the Sky remote control blinks three times then all possible codes for that make of receiver have been checked. Repeat from step one, ensuring that you enter the correct manufacturer code.
At the end of the sequence, if you see the TV Guide screen, the remote control setup process is complete. If you did not see the TV Guide screen, you must now complete the following steps.
8. Press tv on your Sky remote control.
9. Hold down select and the green button together for about two seconds, until the red light on the Sky remote control blinks twice.
10. Key in the number of the channel on your TV that you use for watching satellite TV.
11. Press select on your Sky remote control. The red light blinks twice. The remote control setup process is complete.
If after trying this, you still have problems, call your broadcaster's help desk. For your broadcaster's help desk number, select the Telephone Numbers option from the Services screen.

If none of the codes work then we have two other solutions:

1. Searching For Your Code

If you have tried all of the set-up codes for your brand of equipment ,or yourbrand is not listed, and you are still not able to get the unit to respond, trythe following procedure to search for your code.
If you don't find a code that works, the remote will flash four times when youreach the end of all the codes for this device type.
  1. PRESS the button for the device you want to program, (TV, VCR, CABLE, etc.), then RELEASE.
  2. PRESS and HOLD the SETUP button until the red LED flashes twice, then RELEASE.
  3. ENTER 9-9-1 (two blinks on the remote)
  4. ALTERNATE slowly between the POWER key and the DEVICE (TV, VCR, CABLE, etc.) button until your device turns off. (On VCR, LD, and CD players use PLAY instead of POWER)
    Make sure that the remote is pointed at your device during the search, You may have to press this sequences of buttons up to 100 times to search the entire library of codes.
  5. When your device turns OFF, PRESS the SETUP button and RELEASE it to lock in the code for your device.

2. Learn the buttons from the original

Line up your original remote and the head-to-head before completing thefollowing steps.
  1. PRESS and HOLD the SETUP button until the red LED flashes twice.
  2. PRESS 9 - 7 - 5, the red LED will flash twice.
  3. PRESS the DEVICE key where you wish to learn the function. The next 3 steps must be completed within 10 seconds.
  4. PRESS the button that will receive the learned function, the LED will flash rapidly.
  5. PRESS the button on the original remote to be learned.

Now you can repeat steps 3 through 5 to learn other functions onto other keysor press and hold SETUP until the Cinema's red light flashes twice to lock inyour new feature. (If the red light does not blink twice, stop and repeat stepsthrough 6).
To test the new feature, press and release the device key in which the newfeature was learned followed by the key on which the feature was learned

1.hold down the DVD-VCR button-->the red led will stay lit.
2.while holding down the DVD-VCR button press the number 2 --> the red led will turn off
3.Release the DVD-VCR button--> the red led blinks 4 times and turns off
4.The DVD-VCR button is now set to VCR mode-->program for VCR

BRAND CODE SEARCH ENTRY:
1. turn on device
2. locate brand codes(sorry, I don't have it, try finding genaric RCA codes)
3. hold down the component button--> led should stay on
4. while holding component button, also hold power button--> the led will turn off, then after 3 seconds it will turn back on.
5. release both buttons--> led will stay on
6. enter brand code--> led blinks once
7. press power button repeatedly until component turns off-->each time you press the power key the remote sends a different code for that brand. led blinks once
8. if power on your device turns off press the stop button to save configuration-> led turns off
9. if the led blinks 4 times and turns off, you have reached the end of the codes for that brand, try using a different method to program your device.

DIRECT CODE ENTRY:
1. turn on the device
2. locate your device codes
3. hold component key down-->led lights up and stays lit
4. enter code while holding components key--> as first key is pressed the led turn off, then as 4th digit of key is pressed the led turns back on
5. release component key-->led turns off, try using your remote, if it doesn't have all of the functions you need, try a different code
6. if the led blinks 4 times after entering code you have entered an invalid code, try again.

MANUAL SEARCH AND ENTRY:
1. turn on device
2. hold the component button--> led lights up and stays lit
3. while holding component button hold power button-> led turns off then turns back on after 3 seconds
4. release both buttons--> led stays lit
5. push the power button a bunch of times until the device shuts off-> each time the power button is pressed a different code is sent to the device, the led blinks each time.
6. if the device turns off press the stop button to save your config.
7. if the led blinks 4 times you have reached the end of the code list, there are hundreds of codes, you may be pressing the power button for a while...

AUTO CODE SEARCH AND ENTRY:
