Question about Toshiba 65HX81 65" Rear Projection Television

1 Answer

Toshiba 65hx81 65" Rear Projection tv. black & white color/green

What could be the problem with this TV? I bought this set 5 years ago new and as you would know it the extended warranty has just ran out last month. While watching it the other day we slowly noticed the picture color fading, then green, now it looks black and white or gray. It doesn't matter how many times you turn the TV on or off the color is not right. I disassembled the set and it appears that the green, red and blue bulbs are on and producing light (not sure if they are producing enough light though). While looking into the rear mirror, to me it seem like the bulbs should be brighter, not sure though. While working on the set all the bulbs became really bright and the color was fine for a minute, then instantly went back to the gray/green color. Has anyone experienced this problem and know what the fix could be?

    I pulled the Toshiba Technical Bulletin that described the fix that you suggested (TV0201 REF # 012902). I checked the continuity connection to the main board on both the positive and negative connections to c810 and c809 and both were fine. I checked the fuses on F801 & F860 and those were fine. I am looking for more suggestions to fix this. Do you have any more suggestions or did anyone else experience this problem and know what the fix is? Thanks Techman for your help!

Yep, your problem is a relatively easy one to repair if you know how to solder. You better repair it before it blows the fuse though. There are two capacitors in the main power supply that are coming loose and need to be re soldered. There is a Toshiba service bulletin about it. They are marked C809 and C810 on the main power supply board. Good Luck

    Did you try to resolder it though, as if you did not, you should know, under a current draw the connections can go bad. If that does not work, replace the regulator IC.

Toshiba 50HX81 only showing black and white

I bet it's a DLP TV correct?
This symptom would indicate that the color wheel has flown apart. Which results in a monochrome only image.
Color wheels are expensive and need to be replaced by a qualified service person.

Screen turn green tv is 57 rear projection

Good Day,
It appears that you may have a green drive issue. Try adjusting the Sreen Control it is located in the front of TV.
1) Remove Speaker Grill (it just pulls off) start at one end, 2) Remove cover (5-6 screws), 3) Adjust control. The control is located on lower right side towards bottom. A small black device with 2 rolls of controls, adjust the center control on bottom row counter clock wise, until you get a black and white picture.(adjust with color control to min).
If this does not work you light bulb (CRT) is bad about a $750.00 repair.

Good Luck, Big Irish.

Picture has a green shade

Sounds like your red picture tube is not emitting enough brightness to balance the colors. A temporary solution could be to slightly increase the screen voltage of the red CRT to give a good black and white picture when the color control is turned all the way down. If the set has not been serviced in the last 5 years or so, and you're not ready for a new HDTV set, it may be worthwhile to get a technican to look at it and clean the dust off the lenses and mirror and evaluate whether a picture tube rejuvination might work along with the gray scale tracking adjustments.
