Question about Sony Grand WEGA KDF-42WE655 42" Rear Projection HDTV

1 Answer

I have a Sony Wega 55 inch for about 6 years. I have replaced the bulb twice before. I just got another bulb in the unit. It now works for awhile. It occasionally is shutting down with the 5 blink code. I have read that could be the power supply. I often swap these in desktop computers, but am not sure about a TV? How much would a ballpark pricing be to have someone replace it? How much is the power supply? If this is costly, I have to wonder if a new unit would not be smarter way to go?? Thanks in advance!!

5 blinks, pause, 5 blinks, etc. means "Lamp driver error" and the probable cause listed is "Lamp driver defect".This is the starting point for a qualified service technician.Even so, the actual problem may be the lamp. Did you install a genuine Sony lamp assembly? These sets are bad for the lamp driver and optical block, which Sony has extended a warranty on these sets due to the mass problems that they have had with them. If you haven't contacted them yet please do so and talk to them about a warranty on your set. Sony tells me that while they extended the warranty through 3/2011, so please hurry on this.
The parts you need run between $225.00 and $315.00 depending on what boards you need. IF Sony won't honor the warranty or at least work with you, you may consider a new set, these will only get more costly to keep repairing. I Believe in Sony, its not all their fault, there were a lot of bad electrical supplies sold to the electronics industry a few years ago and they simply don't last.

We had the same problem. Let it be and now the tv won't turn on. If I understand correctly from what I've read it's the optical block and they seem to be just as much as a new tv.

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.

Thanks for using FixYa and for the great rating.

Blue patch on side of screen


This is your Optics Block failing. One of the filters creating this issue. If you don't have warranty (call SONY customer service to check it out) - watch it like it is until you get new TV. It is very expensive repair.

Blue spot on screen center. Peoples faces and show blue tint


if you have a Sony LCD projection ..Theres good chance optical block needs replacing .This spot will get bigger and will eventually cover most of screen the longer you use it .needs repair.If there is no warranty on this unit..I would estimate repair around 6- 8 hundred dollars ..
