Sounds like a thermal fuse.

This error code is an indication of a b+ error voltage ... specifically a voltage of 6 volts known as dd voltage when the voltage is low pin 129 of micro

I would check the power supply for bad capacitors. The caps look like small "barrells" AND THE END WILL BE BULGED OUT IF THEY ARE BAD. Very inexpensive rapair if you do it yourself, caps are around $2 each.

Most likly a bad lamp. A-1606-034-BM2991690 Complete Pricefalls.com , you will find 2 thumb screws on rear of set, remove the front panel, remove lamp install new one in reverse order. BE careful to not bent the door switch.
Please leave feedback

I believ you have an issue with the optical block on your set. Light produced by a high-intensity projection lamp enters the optical block and is split into three paths (one each for red, green, and blue) by a series of lenses, condensers, mirrors, filters, and/or beam splitters. Each color has an LCD assembly with polarizing filters and a liquid crystal microdisplay panel (approximately 1" across). On Sony's "3LCD" models, the light is transmitted through each LCD panel, and, on their "SXRD" (Silicon X-tal Reflective Display) models, the light is reflected off each SXRD panel. Finally, the three separately colored images are combined with a special prism into the final full-color image, which is then projected/enlarged onto the back of the screen by a projection lens.
The following annotated photo shows various parts on the optical block of a 2004 3LCD model KDF-55WF655 (note that the LCD panel cover has been removed):

Either the block is starting to wear out or you have something blocking the lens, such a dirt or something has fallen and is blocking the lens

Its most likely an intermittent lamp. The lamp door is located behind the front panel. The front panel can be removed after loosening the two thumb wheels located on either end of the TV in the rear. Observe the light coming from the area around the lamp door. If you see that the light is going out, its the lamp. You can also access the self-diagnosis menu by using the remote control. Start with the TV off. Push the "mute", then the number 5 button, and then the volume down button followed by the power button. When the picture appears, the menu will been visable. If there is a failure with the lamp, or a fan, or many other areas in the TV there will be a number value to the right of the parameter that indicates the number of times the error has occurred.

Ours did the same thing. We have the same model. Our tech changed the optical block.

Hi Franceg40,
The main reason of your problem is the convergence board gone bad, check first the bad solder joints in the board, you may replace the convergence IC and resistor around or the entire convergence board for your convenience.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Hi,

The most common indications of a weak bulb in a Sony LCD Rear Projection TV are:

• Dimimage with low brightness and contrast.
• NoPicture, Dark Screen.
• Shadowsin Image, sometimes circular.
• Intermittent Shutdown.
• Fluctuating or Flashing Brightness.
• Longerthan Normal starting time.

Also check for distortion caused by Optical Engine Failure. If any of these faults are present, bulb will not fix. Sony Optical Engine Fault Gallery

johnlawre677,

You have a high voltage problem. I have a tip at http://www.fixya.com/support/r7785140-sony_tv_error_code_three_blink_solution which explains the problem, where to get the parts to repair the unit and how to perform the repair.

Thanks for using FixYa and for the great rating. Please consider a testimonial. Thank you.

Hey, is it a side mount, single bulb? My GRAND WEGA had the same problem, I figured it out and now it looks BRAND NEW.

Sony has issued a "Blue Dot Warranty" which is an extended warranty to fix this particular problem on select models. Contact sony.com to see if your tv set is still under the same warranty.

bad lamp, thermal fuse will power up tv. Blue haze is optical block.

When troubleshooting these units, there are always several variables to consider. First check to see what last occurred with the unit such as did the children play video games, did the electricity go out due to bad weather. You may see that there are many possibilities but let's focus on what occurred last to the unit. Once we determine what happened last, we may isolate the actual cause of the problem. The actual cause may be associated with projection issues, older versions (Picture tube), interference from devices located nearby, and even a radio turned on and located really close to your unit. This is normally known as electromagnetic interference to electronics and is very common with the error you have provided today. Please continue to look for anything EXTERNAL to the unit before looking at the internal components. I have been working on these a long time so feel free to follow up with me.

Hi,
It seems lamp/ bulb popped again, check lamp inside tv.
If tv does not show red blinking light then it would be lamp that knocked off, replace lamp in tv to fix its problem, please buy Sony original lamp for good picture in tv.
Let me know if you have additional question.
Thanks.

check the input from either the remote or on the main unit. Change it to input 3 for dish or input 2 for direct cable. This should do the trick.

Hi,
If tv shuts off and turns back On itself than lamp is weak and need to be replaced.
If tv shuts off but does not turns On itself than you will see red light blinking on tv front, let me know how many times it blinks, there would be pause of 3 seconds in blinks so count pause to pause and post here to provide you helpful info about problem.
Thanks.

Go into settings off of the Menu. There should be a "brightness" adjustment there.
