are they blinking lines or just straight across from one side to the other blinking lines is the dlp chip going ( they cost a bit to replace)
no blinking then the mirror could of moved in the back of the tv, happens if the tv is not on level ground. or the dlp board needs adjustment ( happens over time as the plastic moves when hot to cold all the time)
I've had the same problem for about the last 6 months. My workaround which was to leave the tv on 24 7 and just turn off the TWC service box. But now the symptoms are vertical dark lines going all the way across screen. My guess is that it will cost more to fix than worth it. I paid @$2000 for it new in 2004. Technology has gotten better so I may just go out and get a Samsumg for considerably less and be way better off. None of Toshiba's products had done well for me. 2 laptops, 3 tvs, etc. have taught me this.
Several capacitors need replaced in the Hyper Module. It's not something the consumer can repair and the module is not available any longer as new or rebuilt. You should call a service center for an estimate and decide whether to put the money into it.
go into menu and adjust convergence. if red moves, it just needs adjusting from your remote. if it doesnt move or is bent then you have a bad convergence ic. possible fuse. suggest local service center. sorry
It sounds like a convergence problem---go into the customer menu and select convergence---set should offer center and multipoint adjustment--in the multipoint look to see if the outer crosses adjust--if red or blue will not adjust somewhere--bad convergence IC's.
sounds like you have sa bad what is called the hypermodule. ideally the best coarse of action would be to replace this. but do to the fact it is a common problem these cuircit boards are hard to come by. Toshibia has told us service centers how to repair these boards which involves replaceing 11 micro caps very very small compnents that usally involve twezzers and magnifier. not for the do it yoursefer. you can easlly damage the board and if that happens that ends the tv right there. at my shope such a repair runs 250 with the parts and labor but it will depend on the shop it is rather labor intensive even to remove the board
Typically this is a convergence problem and can be repair relatively easy. Refer to this video to determine if you truly have a convergence problem. Also make sure you use your TV's original remote to make this adjustment.
I am assuming that when the set blanks out, you don't notice the power light flashing any certain sequence. What I would try if that is the case, would be to press a button on the remote control to bring up a menu on screen when it blanks out. If you can bring up any writing on screen while the picture is blanked out you know the Lamp is doing its job. Also, do you lose audio when this happens? If so, it could be a problem in the power supply or if you have the cable connected directly into the TV's tuner stub, the problem might lie in the Tuner. If you have On Screen Display when this happens and audio, then it looks like there is a problem in the video circuits of the TV. If you have a cable box hooked into the TV, the problem could be there also. Now you know why the Toshiba Repair Center gets the big bucks to figure out these things.
The convergence adjustment on the TV set are for the center adjustments ONLY. if you cannot get them in or they are way out, then you have a convergence IC problem. Dont feel bad though as it happens to every rear projection set ever made. Good Luck
