How to replace procector lamp in model 46h84 toshiba


Projection TV sets have three tubes - red - blue - green and they don't fail often...they are located inside the tv DLP TV sets use a single bulb and a clot wheel to make the three colors display...DLP bulbs do fail about every two years and will need o be replaced. Replacements can be found at www.TvRepairKits.com and its located behind a small door on the rear of the tv.

Image on screen looks concave(middle of screen looks farther away than left or right side.)


Roseannmace,
Your TV is out of convergance. You'll probably noticed that there are red, green, and blue images. You'll need to determine if the problem is in the power supply or the convergance board. Usually, the convergance amps go bad and opens resistors. Do you know how to read a schematic and use a multimeter? You will also need to know how to remove the old parts and solder the new parts into the circuit board.

I have a toshiba 65hm167 no red color on the screen


Your TV is a DLP one lamp does it all, not like the old projection TVs with the Red, Green & Blue CRTs. Your TV may have a bad light engine or lose cable connections.

Good luck

Toshiba 43HX70 convergence problem


One or both of the STK convergence chips have probably failed.

I can give you guidance on this if you are confident to do the repair. I had the same problem with my Tosh 40WH08B and after replacing these chips it works like new.

Convergence problem


sounds like you need to change the convergence chip to me. you can order a kit with instructions from www.tvrepairkits.com for most tv's.
If you plan on doing this you need a good soldering gun and a steady hand.

Blue Halo - convergence issue with 43Hx70


The most likely cause is shorted convergence chips and possibly a few pico fuses.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony,Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2
Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

You can see some more examples and find a fix herebb0cf99.png http://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull
