Sony Wega projection tv with cirlce emblazened in center of scree


The clown face you see is the cap that the repair man (clown) did not remove from the new optical block he/she installed. The optical Block will have to be either removed from the TV so that the cap can be removed OR a crafty individual could take the screws out from around the screen frame and mirror cover and pop it out using a broom handle with a wad of duck tape on the end. In any case, this is mistake that can easily happen (I have done it), but the picture should have been verified before it was returned to you. Make them fix it in your home. I hope this was helpful, best wishes.

Issue with our Toshiba 50H82 - overnight it has stopped playing DVD's properly - a solid black rectangle obliterates 75% of the screen. Any idea?


Hi,
Do you see same solid black box in all inputs or just in dvd picture?
If solid box appears only with dvd picture then its generated by dvd player, check dvd player Menu and turn off any subtitle settings.
And if solid black rectangular appears in all inputs of TV like cable etc then check Close Caption feature in TV and turn off CC function.
Hope this will solve your TV problem.
Thanks.

Mitsubishi wd52525 problems


i have thought about this since you first posted it. if the demo is good then the light engine is ok. it sounds like a problem in the chassis. probably on the DM and the terminal board. to repair the chassis would cost about $250.00 plus shipping.

OK to help assist everyone having the BLUE HUE and CURVED LINES Issue on their Rear Projection HDTV no matter their model. Here are the steps to take. The first thing to check is the FOCUS BLOCK or G2 Focus Transformer or CRX F-Pack. I have replaced mine, however it didn't resolve the issue. I am onto the next item the CRT Board for Blue (Which is the board under one of the three color lamps inside your tv) Please see photo below (if photo is not large enough below go to link to review notes as well) If the CRT Board is not it, then the next step will be the Signal Board which is a larger board in the back. In a week I will have a picture of both.

INSTRUCTIONS:
  1. Remove the outside cover
  2. Remove the wood plank/panel
  3. In the front is the G2 Focus Block/Transformer, while set is on turn the top 3 knobs till the screen goes black/dark grey.
  4. adjusting the colors till you receive the desired or normal color/picture.
  5. Once you have received the proper color/picture tap the side of the Focus Block.
  6. IF The colors go out of wack again and the blue comes back strong then this "CAN BE" the Focus Block.

Replace the G2 Focus Block aka Focus Transformer, if Hitachi it's called a CRX F-Pack. This item will cost about $50. Not expensive. You will likely need a soldiering iron. DO TURN OFF & UNPLUG THE TV WHEN INSERTING ANY METAL OBJECTS INTO THE TV!!

FOLLOW THE PHOTOS/DIAGRAM in link below for assistance in the above instructions. I will post my next process since it was not my Focus Block that was an issue.
