1997 Toshiba 50 inch tv

Most common problem on Toshiba tv's is the so called nexthyper module thats were your problem is,normaly they have bad ground connections,a tv tech can fix it.

I have fixed the issue on my Toshiba 40" Flat panel. There are several ribbon cables that run across the top of the FPD module. It took a short while to disassemble the entire assembly. The fix I employed was to secure the ribbon cable using black electrical tape. Unfortunately the reassemble revealed an isse where the frame for the FPD module reintroduced the issue. I merely wedged the frame and the assembly and that resolved the issue entirely. I neglected to totally resolder the connections so not to damage any of the other ribbon cables for the display. Note these ribbon cables get very hot to the touch.

I have video's and pictures on request.

It sounds like the picture tube may be weak (because it's orange) but it going to half ascreen is not caused by the picture tube but likely a vertical circuit problem. If this problem happened suddenly (going orange) then the picture tube is probably good and at least worth bringing in for an estimate.

Is it ok when you watch regular TV thru the cable or sat?

Hello! I have a 32" Vizio LCD...within 30 minutes of the tv being turned on, black lines start running through the bottom half of the screen and eventually blacking out the bottom half of the tv screen. It also doesn't have anything to do with the ratio as I have tried that. HELP!

I fixed the problem by taking it to a repair shop

So, where are the answers?

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...
