I too, took off the back of my Sony TV after I started getting red and green shadows (called retrace lines) around words and people; and blew out all the dust inside hoping that would help. Ironically, I discovered that most problems with rear projection TVs are due to a malfunction located in the bottom FRONT panel, accessed by taking off the front speaker panel and then a wooden panel after that to access the circuitry, specifically this little black box with 6 screws on it. Go to www.SomeLifeBlog.com and this site has photos how to take off the front of the tv and instructions how to fix some common problems that repair people will charge you $300-500 to fix. This man, his instructions, photos, and website were a godsend. Good luck.

No power output or display.green standby light flashes.


Sounds like either a blown mainpower fuse or the thermal fuse for the power transformer. If the protect circuit was kicking in, the display would light up, but then turn off with a red blinking light. the green light with no display means the transformer is not getting power.

My Hitachi L42VC04UB replaced a failed power board .The television comes on and after a short time it shuts down and the standby light in the front of the television flashes blue and red .This happe


Well either the TV's main (or other) board overloads the power board and it shuts itself off or the power board itself shuts itself off for whatever reason or the main board shuts off for whatever reason.

With the setup you have I'd say it's probably going to be difficult to figure out which one it is.

You will want to have yet another board - either main or power - to eliminate one of the two most likely possibilities.

What did you do with the original power board?

If you keep it you can probably send it to us for repair....or if it's cheap enough just buy another one.

i don't think there's an easier and affordable way to narrow it down than using a third board.

My Sony KP-46WT500 screen shows the tv image in blue only for a few seconds, then it goes completely blank (as if it were off). Do I need to replace the bulbs?


It is rear projection TV that use 3 picture tubes of red-green-blue to show color picture on tv front screen.
Do you see standby red light blinking when TV shuts off after showing blue image for a while?
If red standby light is blinking, please count it how many times it blinks, there would be 3 seconds pause between blinks so count pause to pause and post it here to find out possible solution.
Thanks.

Sony Bravia KDL 46", no picture, standby light blinks 4 times


Since the TV is still receiving power, the problem is going to be with the TV's mainboard.  After you unplugged the TV and plugged it back in, you said the power light went out again, so I assume the standby light wasn't flashing again?  The flashing standby light is indicating an error code so my suggestion is to contact Sony for service options regardless if there is a warranty or not because service is the only solution to this situation.  Don't forget to provide them the error code or 4 flashes repeating.

Minium is the green picture tube need to be replaced, if you can take the front cover and access panel off there is a control with 3 focus and screen controls.
you can adjust the 3 screen controls to possibly get a little more time out of it before the crt's need to be replaced. careful if you turn them down too much there will be no picture, and if you turn them too high the tv will go bright and shut off

Red Light Flashing 6 times


When the lamp fails in this unit, often the thermal fuse opens. The error code is 6 blinks. To replace this part requires a great deal of deal of disassembly.
