Question about Toshiba 50HX81 50" Rear Projection Television

1 Answer

Convergance/coaxial cables I just replaced the two IC convergance chips. In doing so I had to cut two coaxial cables. I believe that I repaired them properly, by soldering together the inside, insulating it with electical tape, than trying y best to surround it in the copper housing, and taping that. when all was said and done, I turn on the TV and get a blinking red light, and a blank screen. Is it the coaxial cables I didn't fix properly? Did I not install the IC convergance chips correctly? The TV has been off and unpluggged for about 8 months, Could this have anything to do with it... any ideas?

    I used the same exact Chips as the ones that were in already... they were about $10 each. Where exactly are F851 and F852? Thanks for your help, I check the IC chips connection as well.

    The chips were the same type that the TV came with. They were mid-range in price ~$10 each. Thanks for the help, I'll check the resoldered joints. What do F851 and F852 look like?

Its almost always a convergance inverter that has burned out. The IC chips as they are called aren't too cheap, Even the repair shop would suggest a new tv as a cheaper route in the long run. To make your set reliable again the convergance board needs to be rebuilt with all new chips, and pico fuses.

Hitachi projection TV - video is in 3d rainbow

This sounds like a convergence circuit problem. Your set has two convergence IC chips (integrated circuit). One is for the red CRT, the other is for the blue CRT. This is a common issue with projection TVs. It is not a difficult repair if you have any experience with electronics and soldering. Both convergence ICs should be replaced at the same time. The part is IC (STK394-160E) and is available for around $36 or less. If you have a shop fix this they will likely charge $300-$400. If this information was helpful or if you would like to know how to do this repair in more detail post back on this thread. I would be happy to walk you through it.

Tried convergance, but would work

probably need to replace the convergence ICs inside the TV. The Ic is about 2" x 3" and mounted on large aluminum heatsink. Usually 2 or 3 (depends on model)
