Rear projection i lost my remote,my colour is not the best would this be to a mechanical problem, can this model colour be adjusted without the remote

You cant. You will need the remote control to control the adjustments. You can get the remote for your model from www.tvrepairworld.com

You can order the remote for your model through www.tvrepairworld.com they can get any remote for any television. and the remotes dont require any programing since theyre designed to operate a specific model number TV.

You may try to get into the service menu and adjust screens/drives level(procedure below). But first turn the color off completely and adjust you brightness to mid-range, what you`ll want to do is a grey raster or bring it as black and white as you can while adjusting the red/green /blue guns or tubes. Also get a piece of paper and pen because you`ll want to record the original values of the items you may change. You want to go into the adjustment menu. Hope this will help Good luck
In quick sequence on the remote press:
MUTE - 1 - 8 - 2 - POWER buttons.

The TV will turn On with the Service Menu displayed.
ADJUSTMENT - TEST PATTERN - SET OPTION BYTE - FACTORY RESET

Select the function and use the VOL+ button to enter.
Save settings and exit by pushing MUTE twice then POWER .

They adjust FOCUS and Screen settings---they have nothing to do with convergence---if you have not touched them---do not---they are not real easy to reset correctly.

What is wrong with the set and what is the model number?

let me know and I will try to assist you

hi, symptom is caused by mis-adjusted focus, theres mechanical adjustment on lenses, and theres electrical on focus block, if tv was recently moved I would guess it`s mechanical, I strongly recommend you get a tech to do this, good luck video-tek.

If there is no on screen menu option, accessible from the console, that you can switch off, the answer to your
question is "You can't".....without obtaining a universal remote that you will install using the codes for the
function of your particular set, and since you have a rear projection model (61 inches, wow!!) every universal
remote normally used for the purpose of home entertainment theater setups will have the code for your set.

Enjoy!!

You need a new convergence board. Not an easy fix, sorry.

You can't. Best solution = buy a universal programmable SONY
remote for about 12.00.................................T.

You will need to get an original replacement remote or the original to access the menu. An original replacement remote for this TV set is not cheap! You can see what you need here
