Tries tv and cables boxes uplug,replug it back like about an hour later for the tv resetting itself back to the factory setting and those pay boxes updated it softwares.Take the HDMI cable plug it in into another tv HDMI hub.Tv should have signal and work again.
This is a Heat issue with the front sensor of the TV. Dust and Dirt block the sensor causing it to heat up faster and faster. Cleaning the lamp is extremely easy and it will get the TV working again, at least for a short while and then it will happen again. I know cause its been happening to me and it will work for about two weeks and start happening again. Sony actually has a class action lawsuit against them for this issue. Long story short here are the steps to correct the issue:
1. power down TV and disconnect from the power outlet then let sit for 30 minutes until its colled down
2. On the bottom corners of the TV (Back side) you will find a round screw that you can loosen with your fingers
3. once both screws are lose the front bottom part of the TV will pull off, there are magnets there so it will hold it in place temporarily.
4. Once the cover is removed, in the center of the TV will be a little door with another Finger screw to loosen, once off move the bar holding the door closed and remove the plate.
5. You will need an Alan wrench, the screw will be in the upper left corner, when this is loosened the screw will not fall out and you can pull out the Light fixture
6. CAREFULLY with compressed air spray the light assembly and the inside of the TV very well and then replace the light bulb.
7. Put the Door back on the front of the Light area, and assemble the rest of the TV in reverse order before testing the TV. I have done this multiple times as this is not a permanent fix but does restore life for a short period of time.
it would probably be easier to have someone come out and take a look at it before you go buying parts you may not need to be spending money on. it may be a simple fix for a repairman and not so simple for you...
I have a similar problem. Just found out a possible solution yesterday. I am waiting for my lamp but here's what you need to do if you have replaced your lamp. Go into self diagnostics mode: Switch of your TV via remote, you will see red standy by light. Now,on the remote press "Display"=>"Channel 5"=>"Volume Up"=>"Power Button". All these keys need to be pressed within 3 seconds. You will now enter the diagnostics mode. Press "Jump" on remote (bottom right) 3 times and then press "Channel 2" 9 times. The screen will display your current lamp hours used.
In order to reset your tv to factory settings and for the new bulb to work you must reset this timer or else your TV will assume you are still using the old bulb and will automatically kick in "over protection mode". So here's what you do once you do on the lamp hours display screen. Press the "Channel 3" button on the remote 3 times then "Mute" then "Press Enter" to reset the timer to zero. Your TV should now work as normal. And remember, whenever a part is replaced all factory settings must be reset to zero. To do this, follow "Display"=>"Channel 5"=>"Volume Up"=> "Power Up" to enter service mode. Finally, press "Channel 8" and then "Enter" to put the TV back to factory settings.
The above mentioned is usually performed by a service technician and they charge somewhere around $95 diagnostic fee. You just saved this charge. If you see flashing red lights count them when they flash in sequence. This is a code for the techs to tell them what is wrong. These flashing red lights sequentially flash from 0 to 10 times to identify a problem. Usually, when the bbulb goes bad the only thing that might need to be replaced would be a "lamp Driver" aka "Power Block Assembly" $116.25 online from Sony, or the ballast. Sometimes, if you do not have a video a Thermal FUse can go bad which only costs $4.80 for the KDF60-XS955 but the techs will charge you over $300. You can do this yourself if you can get your hands on a service manual.
do this. press and hold device and menu button on set for 5 seconds. this will retrieve a 2 digit error code .. the led will flash the first digit and pause the flash second digit. This unit is known to have capacitor problems on the power board. getting to these capacitors involves taking alot apart. let me know error codes and we can continue troubleshooting
There is a list of things you need to check, but offhand I'd say that the 5 volt line is low and probably right on the"edge", which is why it works sometimes and not others take a look at this list: Cause #1 1. (Lamp may light and go out) suspect bad lamp part # 915P020010 2. Check for 12-volts DC at J-9 connector pin 4 on the Engine Driver PCB, if missing check for an open F9A09 on the Power PCB, if it is open replace F9A09 part # 283P127060 and the Light Engine part # 939P977010 3. (Lamp may light and go out) Check for 5-volts DC at J-9 connector pin 1 and 2 on the Engine Driver PCB if low or missing check C9A37 and C9A38 both 3300 UFD 10 V part # 181P732040 on the Power PCB (part # 930B921002) 4. At power on the lamp turns on and off three times and then the unit shuts down with a red lamp LED (lamp error). Replace the Light Engine part # 939P977010 5. Lamp enable line at J14 pin 6 does not switch to 5 volts after turn on, 12 and 5 volt supplies are good. Suspect the Light Engine part # 939P977010 6. Lamp enable line at connector J14 pin 6 on the Engine Driver PCB switches to 5 volts after turn on and does go to 0-volts (low) after 5 seconds, 12 and 5 volt supplies are good. Suspect the Lamp Power PCB (ballast) part # 939P978010 7. Lamp enable line at connector J14 pin 6 on the Engine Driver PCB switches to 5 volts after turn on but does not go back to 0- volts (low) after 5 seconds, 12 and 5 volt supplies are good. Suspect the Light Engine part # 939P977010
I would say try #3 first, the two caps on the pwer supply board. A couple of warnings: as always, unplug the unit before servicing. The power supply is located on the left side, if you behind the unit. It is in a shielded box and the shield has VERY SHARP EDGES so use care when you try to open it or you will slice your fingers. Please be sure to rate this solution. Thanks!
If picture quality is poor, be sure you aligned the bulb in the correct manner and be sure the cover for the bulb is not loose. Also, you might want to re check you picture setting as it might have gotten reset when you pulled the plug (I hope you pulled the plug when replacing the bulb).
Heres another solution (maybe temporary) to the problem of no picture and no sound for 30 seconds. I had my tv's power saving setting on "standard" before. After I switched it to "reduced", the problem was fixed. It has been almost two weeks without the problem. I think its a good fix until the new bulb comes in the mail.
