Question about Sony Grand WEGA KF50XBR800 50" Rear Projection HDTV-Ready Television

1 Answer

Ghost image - told by tech that optical unit needs to be replaced

My set is actually the 60XBR800. The cost estimate to replace was $1870 including parts, labor and taxes. That is pretty steep, even for a 5 year old set, and I am considering using that money towards a new one. In reading the postings here, there may be a way to avoid this repair by doing a "reconvergence". Is that something I can try by myself? If so, can someone point out how to do it? Any other advice on this problem and their recommended fix would also be appreciated.

Ghost images in blue. convergance adjustment wont move it back. it's only the blue and only to the right

This set uses two of the STK-392-110 and you need to replace both.

If will not adjust this is what is wrong. Total parts cost if you can do it yourself will be under 25 dollars.

Hard part is getting at the parts and being able to solder.

Can you do this if I assist you/

My 53UWX10B has a picture problem. Picture is blue and yellow and the yellow is offset to one side a couple of inches. Gives a "ghost" image.

If the picture is 3d looking in some way----it is a convergence problem; many of these sets have "magic focus" and if it will not correct the problem the two convergence chips need to be replaced---this model should use either STK-392-110 OR -150 CHIPS.

This can be a do it yourself repair if you have some skill and total parts cost on Ebay would be under 25 dollars.

Let me know your skill level here and I will instruct you how to do the fix.

I replaced the lamp on my Sony KF-60XBR800. Now the picture is greenish and yellowish. I was told I might have touched/moved the purity ring/s. Where are they located?

Sony TVs has an Optical Block issue. If there is an issue with the optical block, then there will be green, blue patches or tint on the TV display. Try resetting the TV to the factory settings and try Power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue still persists, then TV may require service. You can contact the Customer relations team and check for the available options. Sony had repaired free of cost for such issues. Hence, contact the customer relations.

Problem with sony 60" rear projection TV

I'm afraid, it is problem of optical block unit (light engine) that produce picture by 3 lcds inbuilt, the blue lcd and its related uv filters become defective and causing this kind of blue hue on screen.
Complete optical unit block (light engine) will be replaced by qualified tech to get tv fixed, light engine is costly part so ask an estimate before sending tv in.

Hey joseph, actually replacing the optical Block is not necessary at all, all you need to do is get into the "Service Mode" of the Tv and change a few setting around, did it a few weeks ago and now my TV looks perfect, no reason to waster $1200 as sony is trying to get over on all us consumers.

Sony KP61HS10 and timewarner digital cable box. Don't know which is the problem. Problem is a blue/white ghost on all channels. Tried unplug both units, tried flash focus. Shadow/ghost is now curved image...

I'm going to guess that these ghosts are of different colors too. This is most likely a convergence problem. Try resoldering the pins on the convergence ICs first. If that fails, replace them.
These ICs are large and black, attached to a heatsink. They will be marked STKxxx.
Keep us posted.

Hitachi Picture Looks Like 3-D or Ghost...

If you have any solid state repair experience and know how to solder, then all you need to do is get the convergence ICs and replace them. Then the set may need to be alighned a bit. You will most likly need a cross hatch generator for that. Yea that price is a bit steep, but it will end up costing you more in the long run, if you mess up the board while soldering or adjusting the set, and after getting the parts and equipment. I would highly advise you to get another estamate for this repair. Good Luck Please do not forget to rate this thread.
