I believe the blue lamp in my Toshiba 57H81 DLP television is going bad. The picture is fine, but the blue aspect is skewed to where the image looks somewhat 3-D. What do i need to fix this?
You need to replace convergence out chips in your Toshiba 57H81 tv by qualified tech because 3-D look picture in rear projection tv shows some thing wrong with convergence output chips.
Your tv model number shows it is rear projection tv that use 3 tubes to make color picture on front screen where as dlp tv use one lamp as back light source to present picture at front screen that is generated in light engine.
These tv dont have a bulb it is 3 ctr screen in side over time they can move. in the back is a black box with 3 screw on them one is red one blue and yellow. these will need to be adjusted. also on the blue ctr there is an adjuster that holds the the screen in place this can move over time this will align the screen back into place. as you have said it want to shake i would adjust the fist one i have said as that is more likely to be the fault.
onthe setting menu there is a screen adjustment sometimes it just may need resting screen come up like this in manual mode but there is automatic mode as well which will put a cross in all 4 corners and set up screen by its self you need to do this some times so try this first.
thank u very much and when turn on get nothing just a red ligh do i need to get a DLP lamp i really appreciate any help it was working great and my aunt let kids move it far and was probably not to easy on it but she said i could have it but too big to keep if i cant fix it and dont want to spend furtune were a new tv is cheaper so thank u for any help u can email me at [email protected] and if do need DLP lamp how do i find out part number cause have a newer tv and got lamp on ebay way cheaper than manufacturer
