HI, Remove the lamp driver and check the connection where the lamp is connected to see if the connectins of the lamp driver are not corroded or bit burned.If it is so then replace it.
The thermal sensor may easily be at fault especially if the indicator error flashes 4 times.
this part is not expensive,you may try it after you check the lamp driver connections and if you decide to replace it,it is found on the right side near the front by looking by the back with the back cover open.
Good luck.

    Part number of the thermal sensor is 190027785 and you can get it trought an autorized sony repair shop or call Sony and ask were to get it.

    do not forget to bypass the door safety switch otherwise set will not work.you can move the switch on one side withe a masking tape but DO NOT FORGET TO REN=MOVE IT FOR SAFETY REASON.

Hi,
4 times red light blinking indicates problem with exhaust fan that is not running and tv shuts down instantly due to protection mode activation.
Please check exhaust fan and make sure its connector is plugged in and fan runs freely.
Thanks.

Power light is flashing 3 times consecutively. When hitting the power button the fan comes on then shuts back down..then starts flashing the red light again..I've recently bought a new lamp and installed...


Put lamp cover back in its place as 3 times blinking light shows lamp cover has not been fixed.
Lamp cover is first thing that you removed to replace lamp in tv, make sure it is fixed securely in its position.

After 10 sec. After start up the tv starts to make a large growling sound for about 5 secs. Then repeats every 15 sec. Sounds like if might be a fan. How many fans in this t.v. . Took the back cover off...


there's 3 fans. 1 by the video board. 1 in the middle of the set infront of the heatsink and 1 behind the lamp. make sure all 3 fans are running and put your ears by them to check. if all of them are running the sound might be coming from your colorwheel. If it sounds like a loud whinning/humming or buzzing noise then more then likely its your colorwheel. Let me know what you find and please rate me. Thanks

Panasonic projection TV does not turn on.


Power LED flashes orange 1 x 5 secs. = 1 of 3 fans stopped. TEMP LED flashes 1 x 5 secs, = Temperature error. Lamp LED flashes 1 x 5 secs. = lamp ballast error. (check lamp 1st.)
Hope this helps.

Samsung hln617w dlp tv won't turn on. Red temp


Had similar problem. Thought it was the lamp. Examined old lamp but it appeared to be good. Ordered a new one anyway. Changed the lamp but the TV screen would not come on. It would make the usual noise as it was going to come on normally but it would cycle 3 times & then turn off. The LED lights in the front panel would indicate a defective lamp. Then read about the ballast. Changed the ballast & still same problem. Tried starting the TV without the lamp installed & noticed that the color wheel did not spin. Removed old color wheel & discovered it was broken. This appears to be the cause of all of my problems. I wish I new earlier of the test-turn on the TV without the lamp being installed & check to see if the color wheel is spinning. Would have save money on the lamp & ballast.

When i try and turn my tv on the power light blinks blue and the fan and lamp light blinks red the everything turns off after about 30sec can i fix this myself


Hi, Does the set come on for about 30 sec.? I had a 50V715 hitachi, it came on for about 30 sec. then shut down and then it would repeat the process. After about 3 wks and alot of other pain, it turned out to be the lamp was weak. Replaced the lamp and all is great! So... it could be your lamp is going bad. Hope this is helpful.

Noise from tv


I had the same problem with a 5065. I purchased and installed a new color wheel and that solved the noise problem. The color wheel has a bearing that gets "dry", and when it fails it does sound like a fan bearing.
