SONY KDF70XBR950 TV. NO PICTURE OR SOUND. FIVE FLASHING RED LIGHT

I have a 2003 Sony KDF 70 XBR 950. I am getting five blinking red lights with no picture or audio. I have inspected the lamp and it shows no signs of failure.
How do I tell if the problem is the lamp driver or the lamp?
If it does need the lamp driver, how do I replace it? Is there a manual?
Any suggestions on where to purchase the parts?
Thanks!

    The TV is about 5 years old. I am the second owner and don't know it the lamp has been replaced.
    I have visually inspected the lamp and cannot see any problems.
    How do I determine whether the problem is the ballast supply or Lamp?
    Thanks.

5 times blink code means Lamp Driver error that can be problem of ballast supply or Lamp.
How old is this TV? Have you replaced Lamp recently?

    OK, suppose lamp has not been replaced yet then? TV needs new lamp.
    It is better and safe way to determine either it is lamp or ballast supply defective by replacing lamp. Testing and checking ballast supply is job of qualified tech because electric shock risk is involve.

I have a sony kdf 50e-2000 the green light goes on then it goes to thr red blinking lamp light. I have no sound or picture. If I replace the lamp light will I get sound and a picture again?


Hi,
Yes, if you have not replaced the lamp since you purchased this TV.
Lamps usually last about 6000 hours.
I've seen lamps last much longer than 6000Hrs, it all depends on the usage.
Remove the lamp from the TV and do a visual inspection, see if there's a crack on the glass or the bulb.
If the TV is few years old then the Lamp may be bad.

For a new Lamp: 800 638-3328

DO NOT BUY the lamp from ebay

Good luck to you.

Hi,
Question shows tv is Sony KDF-60WF655.
Green light blinks when tv gets prepare to fire up lamp, check internal circuits then show picture on front screen.
Red light blinking shows some kind of internal problem during circuit check and protection got activated upon some failure.
Count the red light blink as you will see 3 second long pause and post it here to diagnose what section of tv got problem.
Did you replaced its lamp in last 2-3 years?
Thanks.

Sony KDF-E42A10 rear projection TV. Won't turn on.


Start by changing the lamp. If you got 5 years out of the old one, count your blessings, most folks only get three. The lamp is designed to be replaced by the consumer. Ebay will carry a replacement for you or you can get it directly from rivervalleyelectronics.net. They've got good prices. The lamp door is on the back. Its really easy, give it a shot.

Sony KDF 55WF655 rear Project tv Power/standby light flashing


This would be an error code indicating a problem.  You didn't mention if anything else was going on with the TV as in no picture, or no sound.  If the TV is operating just fine, there could be a bug in the software causing this.  If there is a problem, the best thing would be to contact Sony and relay that error message and go from there.
