Question about Sony KDS-R50XBR1 50" HDTV

3 Answers

TV turns off anf on

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. Sony really had no solution other than leaving it unplugged for a little or making sure it was plugged directly into an outlet. 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?

    I have the same model with the same problem. I have had the unit about 20 months. Used to have DirecTV, no issue. Switched to Verizon FioZ about 5 months ago and the problems started. Like somebody suggested I unplugged the HDMI, power cables and I have the same problem. It has gotten worse, shuts down about every couple minutes. HELP>>>>>>>

    TV turns off and on. Problem has gotten worse in the last couple of days. TV was purchased in May of 06. This is the second major problem with this TV. The color-block has been replaced.

    I'm having the same problem. Originally it was every now and then. Had Best Buy out to fix it during warranty but they couldn't find a problem and they were unable to do anything if it didn't do it while they were there. Problem seemed to go away for a while. Now it's back and it does it every 15 minutes or so. Shut off, green light blinks a while and comes back on. I talked to Sony and they blew me off even though it was a pre-existing condition while it was under warranty. It's almost beyond usable. We're now considering calling our Attorney General and the BBB. This is ridiculous...$3000 for a tv that lasts a year and a half. We also have had the light engine replaced because colors were bleeding. I've tried unplugging the tv for a while but no help.

    My same model TV has the same on/off problem. It was purchased on May 06, now is just unusable because it switch on/off every 2-3 minutes. Please let me know if you had same problem and found a fix. Thanks a ton.

    I have the 60xbr1. Same issue. Bought in Jan 06. Sony was less then helpful. Checked the lamp, fans, put it on high altitude mode ( just in case was getting to hot) unplugged plugged directly to a wall outlet nothing is a 3,750 dollars piece of junk in less than 2 years. We should join forces and sue Sony again for this issue.

    I have the same problem. It stays on for 2-3 minutes and then goes off for 20-30 seconds...... This is unacceptable. Any one out there with a fix?

    I've gonne over the Operating Instructions looking for a solution but there is nothing there. Sony should admit to the problem and order a recall.

  • Frednecker Feb 17, 2008

    I also have the same problem...on off...I have the repair guy coming out and will let all know what they say.

    Mine did the same thing. I replaced the lamp and it works fine now. There was alot on dust on the vents for the lamp. The lamp was 3 1/2 years old so I did not mind replacing it,

    I'm having the same problem just started today Sony told me the exact same thing as you unplug it. Just got the thing fixed 6 months ago from recall they had. Has anybody found a solution yet I'm assuming the tech. I call will be out next week and charge me hundreds of $ to get it to work for another 6 months.

    I'm having the same issue with my XBR50 the tv will shut off but the green power light stays lit. It will come back on after a few seconds or up to a few minutes.I had a repair man out and he said it was impossible. I argued for a while and he finally called Sony tech support and they agreed with him, but they told him to "replace the guts" because it could be losing communication between the two.The repair man said it is a very expensive repair because it contains 80% of the television's electronic parts. Thank goodness I have extended warranty.

I have the same problem with a KDS-R50XBR1. The video and audio goes off, the power/standby indicator blinks green 52 times and then the picture and sound comes back, until it does it again. I haven't found any definitive technical info to help troubleshoot. Sony Customer Service was no help.

I replaced the lamp and the problem went away for several weeks, then it started back but only infrequently. It has increased somewhat in frequency over a few months. It acts like it might be related to a component in the lamp power circuit overheating and tripping a limit switch until it cools down and comes back on. I don't know if there is such a limit in the circuit, this is only based on the symptoms I observed. The older the lamp the more frequently it seems to happen.

Several times I've even had the video/audio go out and the red lamp indicator blink. After trying several different things (unplugging the TV, removing/replacing the lamp housing, cleaning the cooling fan, etc.), I've been able to get it to come back, but the cause was not clear to me. Once, when this happened, I tried putting the old lamp back in and it came back on but it triped off/on more frequently, just like it did with this lamp before I had replaced it. I then put the replacement lamp back in and it worked, it went back to the much longer trip cycle. I'm suspecting the lamp ballast/power supply block is causing the problem but I havent tried replacing it yet to confirm my suspicion. That is the next thing to try.

I don't trust that having a local service call would be successful without the tech replacing all of the parts that could possibility cause the problem. That would cost more than the TV is worth.

There have been an exceptional number of costly problems associated with this TV and, while the picture is very good and I like the TV when it is working properly, there comes a time when it doesn't make sense to continue throwing good money after bad. Sony customer service has been very poor too and, after my experience with this product, I'm rethinking my opinion about all Sony products.

I finally got this problem fixed. I posted on another forum and found that when a bulb starts to go bad it can cause these TVs to do strange things. You can replace the bulb for less than half the cost of replacing the whole housing. See how here:

Power shutting off and coming back on

The problem is your bulb is going out or malfunctioning. I had this same problem and Sony's repair service couldn't fix it. I posted on another forum and found a great tv repairman that told me that when the lamp is going out or bad that it can cause the tv to do strange things. I replaced the bulb and the problem is gone. Here's a tip, you can replace just the bulb for about half the price of the full lamp assembly. Sony wants $250 but I bought just the bulb for $125 on ebay, spent 20 minutes taking apart the housing to replace the bulb. Just make sure you take note of how the spring is installed before you take the first part off. Other than that, piece of cake.
