Sony KDS-R50XBR1 shutting off

My Sony tv is randomly shutting off and coming back on. It can go for several hours or it could be every two or three minutes. I've had the tv for about a year and it shows no other problems. Sony really had no solution other than leaving it unplugged for a little or making sure it was plugged directly into an outlet. I have an extended warranty and have contacted a repair man. They haven't come out to look at it yet, but they think it could be the lamp. The problem is if it turns out to be a lamp, the warranty won't pay for the service call because the lamp coverage I have is just for parts so I want to see if I can figure this out before having the repair man come out. The lamp indicator trouble light on the front of the tv is not lit and the tv doesn't blink in red for the trouble codes when it shuts off. Any ideas?

Re: Sony KDS-R50XBR1 shutting off

My Sony was doing this too. The tech found that the reflector around the bulb was cracked probably from overheating of the bulb. The TV was shutting down to cool down the bulb. This fixed the problem. I had over 6000 hrs anyways on my bulb. HTHs

Re: Sony KDS-R50XBR1 shutting off

When the lamp becomes weak in this Sony the unit will shut off intermittently. I would replace the lamp and use only an OEM Sony lamp, not an LTI or other knock off. The knock off lamps are of poor quality in my experience and opinion.

I have a Sony KDS-R50XBR1. it worked fine last night, this morning however, it did not come on at all. it blinks green for awhile, then blinks red continuesly. what is wrong? please help.

The red blinks are a diagnostic tool. If you search this site for KDS-R50XBR1 you will see several problems and the area to look in to. the red blinks should be followed by a three second pause and then repeat. Just count the blinks after the pause and you should have a better idea of what is wrong. The service manual goes all the way up to ten blinks.

TV comes on and then shuts off,and a small red l keeps flashing.

If its flashing red repeating groups of three then the lamp door is not detected .
If its flashing in groups of four then a fan is not starting.Look in the vent in the back and spray some canned air into then big fan on the left(looking at it from the back) .That fan may be failing and has gotten to a place where it can't quite start again and just moving it a little with some air will make it work for a while.
If its not one of those two things let me know.

Sony kds-r50xbr1 turns itself off and then green light blinks 52

I too have a Sony KDS-R60XBR1 tv and the issue that you are experiencing is due to one of your fans in the rear of the tv is not working.  The tv automatically shuts off in protective mode.  Make sure the POWER/STANDBY light is blinking and not the lamp light below it.  Is the power/standby blinking 4 times in red? If, yes then its a fan that needs to be replaced.  If its the lamp light blinking then you need to replace the lamp.  The lamp is easy to replace by ordering the lamp either from Sony for $250 or find it cheaper for approx. $150 from other DLP sources and replace youself by following your manual.  I hope this helps you.

WEGA only show yellow

Hello watts74:

When you turn your tv on, you still get an image of whatever channel you are on, but the background on the entire screen is green/yellow, correct? If so, the problem is the optical block. Read what I posted below on another thread and you should be on your way to getting your situation resolved.

Here is the link to the other thread I mentioned:

If your SONY KDS-R50XBR1 or KDS-R60XBR1 color screen suddenly turns green, the optical block (aka light engine) is the culprit. Don't fret because as "Leadtech" has already posted back on Jul 04, 2007, SONY is aware of this problem and has extended the warranty to replace this very part. Additionally, and aside from the class action lawsuit currently pending in district court, parts and labor for in-house service IS included.

SONY states the warranty as follows:

"As part of the Sony commitment to quality, Sony is announcing that it is extending the limited warranty (parts and labor), in the United States, on the optical block of KDS-R50XBR1 and KDS-R60XBR1 model SXRD televisions until October 31, 2008, regardless of purchase date."

So all you have to do is:

1) Contact SONY Customer Service at (800) 222-7669 or (888) 772-7669 - Hours: Mon-Fri 9:00AM-10:00PM / Sat-Sun 10:30AM-7:15PM EST

2) Provide them with your model (as above) and your television's serial number

3) Tell them your screen color is nothing but green

4) They will provide you with a case number

5) They will ask you for your zip code and provide you with one or more SONY authorized service dealers, and their contact information.

6) You contact the dealer of your choice and schedule an in-house service. Explain to them that your screen is green and you are aware that many, same tv-model owners that have had this same problem, and that the optical block is the problem.

7) The SONY authorized dealer you speak with will schedule and appointment with you, and will provide in-house service.

Regarding the service, it will take about an hour to complete. Not that it is complicated for the technician, but where the optical block is located is that is time-consuming. It sits just "behind" the bottom of the tv screen and in order to get to it, the technician will have to:

1) Remove the bottom back gray cover

2) Remove the replaceable projection lamp located on the left side of the tv (looking from the back)

3) Remove lots of phillips screws

4) Disconnect many plugs

5) Remove 3 chassis closest to the back of the tv before getting to the optical block chassis, which is located up front, just behind the tv screen

Once the optical block is replaced, you will be amazed on correct color results.

Hope this helps...
