Question about Projection Televisions

2 Answers

Hi I have a 50HX81 Toshiba Cinema Series rear projection TV. About three weeks ago mid way thru watching a show, the left lower quadrant messed up. The colors were seperated in an arch. The greens were like an arch. The rest were ok. I tried the 56 convergence correction, but in vain. One could clearly see the green out in an arch and wouldnot correct. Now the top two corners are also distorted, the green are curved upwards like horns. Could someone help in advicing what the solution to this problem could be. Also if it is the convergence board, what part number and what would it look like. What might be the possible fixing cost if I had to call a service tech? Appreciate any help out there. AKR

A refection mirror may be knocked off or have something spilled on it (possibly a leak) from the tv

The STK ic on your board requires replacement . if you call a technical person to get it done it wont cost you much. you can say just a bit more than the service charge. calling a technician is the best option i can suggest. thanks

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.

Toshiba TV 50HX81


Check fuses on Power Supply board (F850, F851, F852) and all other fuses. Replace blown fuses (will need an ohm meter to check fuses). I would also replace the two convergence amps (STK392-110's on the signal board, the big black ICs on the two heat sinks). This worked for me.
