Toshiba TLP560 miscoloring pattern

Hi,
Please help, I have a miscoloring fixed pattern on my projected picture (red on black, black replacing red in the area, etc). It's not only in corners, it's a semi-circular pattern almost all-over, very disturbing. I saw another piece of advice talking about the polarising filter possibly being tarnished because of over-heating. Replacing this one should fix the problem, it was said. I've disassembled my projector up to the point I have been wondering where the filter is, actually. I've attached for you a picture with the insides of my projector. Are those indicated by the red arrows, or the panels indicated by the green arrows, or which?

Thank you!
P.S. I have replaced the lamp, nothing changed.

    I looked again and again and I think I can see the problem: one of the metallic frames (from the right, with a red arrow pointing in my picture) contains a damaged plastic thing. As I looked more carafully, I could see that it was, apparently, the RED color thing. So, unless I am terribly wrong, this should be the melted filter in question that I need to replace.
    Question remains: which would be the best solution to improvise a replacement for this filter?
    1. I guess they do not come as official spare parts, do they?
    2. A photographic filter will stand all that heat? Is that the only choice I'm having?

    Thanks for any hint.

    ANY SOLUTION TO IMPROVIZE A REPLACEMENT?

    Hi,

    I have exactly the same problem (may be a manufacturing design weakness).

    I tried to replace that polarizing filter to another ones that I found in old cellphone LCD screens. It works, but the result wasn't so satisfactory. Although the good reproducing image (specially in shine regions) the black still a with a bit red background. The reason is because the polarizers I've found was not so good in terms of minimum transmittance.

    Now I'm also looking for a photographic polarizer to replace it. I guess that the best ones for us are the "Linear Polarizers" (LPL) instead of "Circular Polarizers" (CPL), the most common ones.

    Once we buy the LPL we need to take care to the right orientation before cut it. A good way to find the right orientation is using the original (half-burned) as reference: put it over any LCD screen (those monochromatic with silver background reflector) and turn-it to find the orientation where the transmittance ritches the minimum (intersection becomes all black) and try to do the same with the new LPL.

    Please, let me know if you do.

    Best regards,

    Zurita

If you are connected to a HD cable box or sat. rcvr. using component cables, I would then suspect a loose or bad blue connection or cable. If you have Comcast and have their supplied flat component cable this is a common issue.

Some newer sets appear that way when there is NO signal to the set. That and my Sony looks like that when the bulb is burned out.

SOURCE: Hi, I need some help (BIOS locked)...

ok i found a couple more things...apparently you dont have to remove the battery.. I found this site that tells you two "jumpers" (solder squares) C88 i believe under the network card. But if you follow this link and follow the directions it will get you going again.

I don't know exactly at what stage you are at and i hope i didn't cause any trouble but this normally is how we take care of this problem. Unless once in a blue moon we come across one like this.

SOURCE: Bulb Replacement

the bulb hot indication has nothing to do with the lamp counter.u would have reset the counter as suggetsed by the manufacturer,
this problem is because of the following:
1) wrong bulb
2) cooling fans not working adequately
3) defective ballast
check the above for a solution

SOURCE: I heard a pop and now the projector only shows black and white.

The color wheel has failed in youtr projector. There are 4 pieces of glass in the color wheel which fit togeter in a "pie" formation and they are red, blue, yellow & clear. This wheel is spun by a motor. The glass is glued to the motor's hub, and, when it fails the glass segments are thown off the hub. This gives you a B&W picture because all of the light is allowed to shine through the optics all of the time. Replace the color wheel with Toshiba part no: 23125963. It will be about $65. No soldering is involved, just use care with the ribbon cable to the motor. You will need a no. 2 phillips screwdriver and a set of jeweles screwdrivers to do this.

The easiest way I have found to set the screen controls is to tune into an old black and white show, turn the green up until you see retrace then slowly turn it down until it just dissapears then adjust the blue and red for a true black and white picture.

Need to test F470 and F850 for open.. Simple continuity to see if either fuse is open.. If F 470 is open replace it and C884 and if F850 is open you probably you may need to replace the two convergence amps STK392-110... Large black Ic's screwed on an aluminum heat sink...

No picture, but power light and sound OK


The problem you have there was a loss of vertical deflection followed by a complete failure of Q301, the vertical Ic LA7833S.
It may have been in part due to the feed caps located in that circuit and there will likely be NO outward signs of the failure.
The Ic needs to be replaced and the electrolytics in that circuit need to be measured with and ESR meter and replaced if bad.
If it's starting to sound a bit beyond your ability I strongly suggest having a qualified shop do this because you can overheat the vert Ic easily just soldering it in...
If you have a shop do it you might ask what they charge to replace the vertical Ic and ESR the caps in that circuit. Explain to them what you have here with regards to how it went out, dropping to a horizontal line before going completely dead... The more detail you can give the easier it will be for the tech to troubleshoot the problem.
Good Luck!
Bill
