SOURCE: colour problem on rear projection tv

This might be something really simple... In a large number of DPTV310 chassis, of which this TV is, the yoke connections where put in place with black electrical tape just below the retaining rings. Job is to loosen the rings, remove the tape and push the yoke back in place and tighten down retainer.. Be careful not to throw off the tilt of the yoke. The adhesive on the tape, over time, gets hot so many time it becomes slippery and allows the yoke to fall away from it's position dulling the look of the image (or focal length) causing the problem you're describing here... It also throws off the convergence - so in attempting to converge it just looks worse. Good Luck Bill

SOURCE: My Sharp LCD 26" TV

the problem with LCD tvs are that they have back lamps that shine thru the LCD sceen. the job of the screen is to block the light of the different colors to make the picture. the problem is that the very thin screen can not block all the light. if the set has a back lamp setting turn down the back lamps and adjust the brightness control it should help a little. you my notice that the blacks and dark sceens look better when the room is fully lit and look much worse in a darken room.

Reset will not cure a convergence problem.

this model (ws-65711) uses a single convergence chip located on the middle circuit board (see photo).

If convergence is skewed and will not adjust in customer menu the chip needs to be replaced.

Good news: I have start to finish, step by step instructions for this repair in this set. They tell you everything you will need and exactly how to do the repair.

No two sets with convergence problems will look exactly the same but I will also attach a few photos of this kind of trouble.

If the photos or what I have told you told you something you did not know and you want the instructions (free) rate this solution as very helpful as I do this here for free.

There is a Video problem with my Samsung LCD. The sound is clear but Colour Balance Setting is disturb. The Colour is mixing with each other. Can You tell me the procedure for My TV Setting?


Before you set up try a reset

Resetting The Picture And Sound To The Factory Settings
as far as advanced settings are concerned, set the contrast backlight and brightness so you can see the best blacks without it looking too milky, the best whites so you can discern the whites and they aren't clipped, then look at colour balance if it looks wrong when you turn the colour off.

Sony bravia problems....intermittent fault. Colour turns psychedelic. Looks like TV is "on acid"!! Sometimes TV can run normally for several hours before the colour fault occurs.


You have a defective T-Con board. The small board near the top center of tv. Can not give you the part number without knowing your TV model. Depending on model $50-120 for part.
