Question about Sony KP-51HW40 51" Rear Projection Television

1 Answer

Great picture

*The set "blinks" 9 times when turned on initially, then when I shut the TV down, and turn it back blinks 4 times. Still no picture. *The "self diagnosis screen display" has the following errors... 4:v stop 1 5:AKB 1 8:HV 1 All other catagories register "0". *There is a "blue" line across the bottom portion of the blank screen. *There is a "black" bar at the bottom of the screen as well. *When the lights are out, and the TV is on, you can see faint images on the screen, but not definitive enough to make out what the images are. That's about it...if any one has any ideas, I would appreciate your help.

Sony kdl52xbr9 it comes on i can see picture and sound for a couple of seconds, then it shuts off and blinks 6 times

Hi! and Welcome to Fixya!

Blinking red lights on the tv are error codes that explains hardware issues on the tv.

However, if after turning ON the tv and you will see the Sony logo on the screen before the picture goes off and then flashes red lights for a number of times, this could mean that tv can still be recovered. Try the option below to isolate possible issue with settings that cause your tv to shut off. Disconnect first all external devices from the tv

1. Turn ON tv first and wait until it flashes the red lights > press and hold down the UP Arrow button ( use remote control ) > while holding down the UP Arrow button, press the POWER button on the tv > tv turns off, wait until it turns on by itself > release the UP Arrow button when tv turns on

Note: reset is successful when you see a welcome screen on the tv and ask you to select your Language. This is the Initial Setup, just follow the on-screen instruction

If that solution did not resolve the issue then a service may be recquired.

Let me know if this helps!

Re: tv kdl-55ex620 red light blink 8 times Do a Power Reset. 1. While the TV is off, unplug the power cord of the TV from the electrical outlet. 2. Let the TV remain without power for 60 seconds. 3. Plug the power cord back into the electrical outlet. (If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.) 4. Turn on the TV. 5. When the TV powers on and a picture is displayed, reset the TV to factory default settings.
  • If the Reset message does not appear and the TV turns off and on, begin again from step 5.
  • If the standby light begins blinking eight times, return to step 1.
6. After the Reset message appears, allow the TV to reset. Do not press any buttons on the remote control or on the TV and do not make any other adjustments for 1 minute. 7. Unplug the power cord from the electrical outlet. 8. Allow the TV to remain without power for 10 seconds. 9. Plug the power cord back into the electrical outlet. 10. Turn on the TV.
  • The initial setup screen displays if the above procedures were performed correctly.
11. Follow the on-screen instructions to complete the initial set up. 12. Perform a system software (firmware) update.

My Mitsubishi Medallion tv stays on for about 10 minutes and then shuts down and won't turn back on until a period of time has passed. It is a rear projection tv about 9 years old. Can anyone help ex

When it shuts off and the green power light goes off, press both the menu and input buttons on the front of the set (not the remote) and hold both for about five seconds and release.

Power light will blink a two digit error code like 2 blinks and then 3 blinks and repeat it several times.

What is the error code?

TV turns on but turns itself off after short amounts of time

This set is equipped with LED diagnostics. Once it shuts down on the front of the set hold down the MENU and INPUT, (sometimes labeled DEVICE) buttons until the LED starts blinking a 2 blink sequence. For example one blink pause two blinks long pause and then repeats is the code for no problem. All of the fault codes begin with two blinks and then one through 4 blinks. I suspect that yours will be a 2 - 4 code because of loss of vertical sweep. Which is bad solder connections on the deflection yokes. A common problem with these units.

Sony Bravia KDL 46", no picture, standby light blinks 4 times

Since the TV is still receiving power, the problem is going to be with the TV's mainboard.  After you unplugged the TV and plugged it back in, you said the power light went out again, so I assume the standby light wasn't flashing again?  The flashing standby light is indicating an error code so my suggestion is to contact Sony for service options regardless if there is a warranty or not because service is the only solution to this situation.  Don't forget to provide them the error code or 4 flashes repeating.
