was the button sequence given (set off) display,5, volume up, then power?

If its the model indicated here or one similar(kdf-55xs955) you may be seeing a lamp that is about to fail.A lot of these just before lamp failure will get very dark and if bad enough the set will even shut off.

college remote code for sony should be 0000

Yup, it seems a lamp problem can give a blinking green light over the 10 times (1 - 10 times for diagnostic codes), but in my case rather than replace the bulb if it works for a minute then resets with the green light blinking, do what I did.Take the lamp out and inspect it, it has breather screens top and bottom, if it cant breath because there clogged with dust, clean them, and you can remove the screens, use q-tips and clean the inside. I saved the cost of a lamp and it's working fine!

3 blinks should on this model mean "LAMP DOOR IS NOT CLOSED" BUT IT really means something else.Can I assist you?I can tell you how to prove this or not and if proved it is a simple and not expensive repair..SD TECH

There is a high possibility that the components over a period of heating and cooling, tend to bring on a problem of dry soldering. So my advice is to check the set for some loose joints that have played on to give you these erratic shut downs or poor performance. The best way to check for loose connections is to tap lightly when the set is powered on, if there is change while tapping then it seems that there are DRY solder joints. Remove main plug, the covers - with caution of high voltage, check for dry joints, and use a good soldering iron to solder all suspected points. Sometimes the fault occurs when the set warms up; if so you can simulate the heat using a hair dryer on the suspected areas, try with the power supply, distribution, Processor controller, driver controllers on the A/V related sections. Also the use a FREEZE-IT spray can simulate the components to cool and show up the fault. It can also be related to WEAK ELECTROLYTIC capacitors as the value can reduce in time. Based on the above method you must be able to locate the area of fault and solder the sections.

That can be caused by either the G1 or the G2 board. However the G1 board is more suspect for the 10 Blink error code. You can get both boards from www.tvrepairworld.com

The fan going off can very well be the cause of this problem. Please messure the DC voltage being supplied to the fan and let me know . Also get me the board marking of teh fan(EX; Fan 01, 02, etc.) as your set has 4 fans. Please provide this info so that I can tell you if its the fan thats faulty or the circuit that its drawing power from.

To reach the thermal fuse you will have to remove the optical block assembly. Remove the back of the tv, about 12 screws. Removed the large support plate, and the small support bar on the left. Remove the buttom screw on the large fan on the lower right. Remove the connections to the bass speaker and the fan connections. Slighty lift on the large board assembly on the left and it comes right out after the small support is removed. There are two hidden screws holding in the optical block. You will need a long phillips screwdriver to loosens these two screws. They will loosen, but not come out. This will allow you to remove the optical block enough to to get to the front section of the TV. You should see the bulb attached to the optical block. If you look close, where the bulb was resting, there is a plastic plate with two screws, and a wire running through it. That is the Thermal Fuse. Remove the two screws and you will be able to remove the Fuse. Install the new fuse and reassemble. I recommend you remove the cooling fan on mounted above the bulb and clean it. This fan gets very dirty. Good luck.

I have a Sony Grand Wega 55 HDTV, Its 6 years old. Problem is as follows: I press the power button and the TV warms up and goes on for about 30 seconds than shuts off to a no power screen , with the power light flashing green. Than after about 60 seconds the TV comes back on for about another 30 sec and shuts off again. The longer i leave the TV on the longer it stays off when it starts blinking the green light. Can anyone tell me if its the sensor or something else? Is the part I need attainable with the ability to replace it myself.
Look forward to your replies.

julian1390,

That could certainly be your problem. If the unit has not had the lamp changed in the last 3 years it ceratinly would not hurt to do that. Even if this is not the problem you will have a replacement lamp for the time in future when the lamp does go. I have a tip at http://www.fixya.com/support/r4168009-change_lamp_in_dlp_projection_tv which will help you do this.

Hi,

Please make sure that the Standby light or the Lamp light of the TV is blinking. The light blinking of the TV indicates to the service code and be easily identified with the help of a service technician. If the Lamp light of the TV is blinking, then it indicates that the Lamp requires a replacement. The TV will cycles on standby mode if there is any internal malfunction in the TV.
You can try removing the connected devices from the TV to check if the issue is with the connected devices.
Turn the power of the TV to off and remove the power cord from the wall outlet.
Reconnect the TV directly to a working wall outlet and check if it works. Please remove any power surge protector if connected.
Also make sure that the TV is properly ventilated.

If the issue persists after the troubleshooting steps, then service may be required.

Thanks for contacting FixYa.
