I've recently acquired a Toshiba 42H83 RPTV. The previous owner said it was messed up, and had some issues. I figured it's definitely worth a look.
From the first power on, I noticed a few things. The image was completely out of whack, convergence issues, and you couldn't realign them. The image was bent on the south sides, blue on the right, red on the left. (red.jpg and blue.jpg in the attachments show what the images did when I tried a touch focus. Green looked fine to my knowledge. All vertical lines were straight.) You could access everything as if the unit was fully functional, but the image was just terrible. Green seemed to be best of the three, however.
When you were looking at the menu, with just the white fuzz going, everything looked like it was bowed towards the rear of the projector (menu.png). The white fuzz seemed to have a flow pattern to it (white fuzz flow guide.png), if that aids in the problem solving at all. After surfing for awhile here, I was thinking it had to do with the ICs; now I think it's a combination of two or so issues.
Recently, the TV has seized to produce an image at all now. Sometimes I'll get a flashing power light; no picture. Others, it'll power on as if it's fully functional, produce no picture, but I can hear the speakers fuzz meaning I'm getting sound. Then, there're times when I'll power it on, and it'll make a clicking sound, and the red power light will completely shut off, then come back on again and make a few clicks and just idle.
Sorry for making it extremely descriptive, and not very short and to the point, but I'm not really sure how else to describe it. haha.
Annnyyyy thoughts at all would be greatly appreciated.

"one hand behind your back" method, and carefully slide the flat of the blade under the anode cap. You need to be very careful not to damage the cap nor scratch the tube surface. Aim towards the center of the cap until you touch the anode contact. You may or may not hear a "snap" as the tube discharges. Once you are sure you have discharged the tube, then again see the illustrations on removal.
