Sony Grand WEGA KDF-42WE655 42" Rear Projection HDTV - Answered Questions & Fixed issues

From what it seems in your question... the problem has already went away... However, I actually know about this. There is a fuse inside the tv near the power button called B-3a... If you replace that fuse it should help fix permanently

There is a separate IC on the main board that does nothing but process the HDMI signal, basically if your using the cable, AVI or any other input other than HDMI and chances are that is bad, it can be replaced if you have a lot of electronic experience, its a $3 chip but its not easy to replace..I would replace the main board if you can find one, sometimes main boards are hard to find..below is a link to the service manual.

Sony uses standard light error codes: I’m happy to help further over the phone at https://www.6ya.com/expert/donald_f2ed37026a3ac881

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/

The KDF-42WE655 does not have a USB port. The current Roku sticks plug into the HDMI port on the TV. You will need to use the power adapter that came with the unit. Plug the USB cord (mini or micro USB) into the back (or side) of the Roku Stick and then plug the power adapter into a nearby power outlet. (It's a 5V 1A DC power adapter.) Roku sells this adapter separately on their Accessories page: https://www.roku.com/accessories . It's ~$10. If you have mounted your TV such that the power outlet is hidden behind the TV, you'll get to the outlet or use another nearby outlet. (Make sure to avoid a tripping hazard if you use an extension cord or power strip to increase the number of available outlets.) I hope this helps. Cindy Wells

could be a number of things-lens film/cover "cloudy", lamp dimming, defective optical block, etc - this tv is garbage! we finally threw ours out for garbage - two lamps exploded at $100-300 - replaced the optical block twice-garbage is all I can say - I expect to buy a tv at 4K that would last many years without distortion to our eyes, the expense of it all and total inconvenience-dealing with warranty bs etc - never owned a tv that was so much trouble!

I have a lcd tv that has a few black dots but it may be from a similar cause. During a move the screen was rubbed against i was wiping the screen later and picked a small piece of plastic off the screen. The moral is... the screens are sensitive to the touch and you should be carefull how you clean it. When i bought my tv i also bought a spray of deionized water. There must be reasons behind why we can't use windex or other chemicals on a screen these days.

This TV is garbage! Finally through mine out in the garbage - replaced the lamp cost from $100-300 - both lamps exploded - replaced optical block twice - lens very distorted - plain old garbage! I will never buy sony products again especially since I paid 4,000 for this tv it was new tech at the time and I was desperate for a tv - sad I am!

Have you tried a new lamp? part# XL-2100U http://www.amazon.com/s/?ie=UTF8&keywords=kdf+42we655+lamp&tag=googhydr-20&index=aps&hvadid=11921412715&hvpos=1t1&hvexid=&hvnetw=s&hvrand=3364425441565700629&hvpone=&hvptwo=&hvqmt=b&hvdev=c&ref=pd_sl_4yvhj7wiks_b pricing varies

Hello the optical block is located at the center bottom of the set. It is a multi-step process to change it,and there is a video on youtube that explains it, but with the age of the set and the expense of the part whether it is a feasible repair. here is a photo of the location and the part itself. The part number is A1084658A-R and the cheapest place I have found it is through Tri State Modules, but I have never used one of their rebuilt optical blocks....thanks

The usual cause of pixel breakup, of all TV's, is a poor signal coming into the TV. us.sanyo.com/Customer-Support

we bought our Sony Wega in 2006 - we changed the bulb twice both times they exploded; we threw this tv out one month ago - sorry but its literally GARBAGE! within the first year the optical block went, then the replacement under my extended warranty that optical block was defective-within a month all the purple hues started showing up again - warranty over - never will I purchase a 4,000 tv nor any sony products ever again! the only good product I ever liked of sony was the Walkman!

Hello, on the Sony remote in the darker gray area is the "wide" button (second row, second button), press it until your set is in the "full" mode. If your screen is still not filled out, it may be the cable box or satellite receiver that needs to be set. With the tv in "full" mode, then set your cable box or satellite receiver to the proper screen setting by using the "format" button on your cable box or satellite receiver remote.

there are several fans on this unit, but the one that seems to give most problem is the one right behind the LAMP. these usually fail because of the heat, age & the accumulation of dust. BE SURE TO VACUUM ALL THE DUST FROM UNIT in order for it to run cooler. Dust causes HEAT..HEAT DESTROYS ELECTRONIC COMPONENTS.

This may be your lamp fan not spinning. Sometimes you can get it to operate temporarily by cleaning the dust from it & spin the blade by hand to get it started
