How do i adjust convergence on a 55 inch toshiba


You need an original working Toshiba remote: two choices here--in the customer menu there will be an option for this and there is a hidden tech menu for finer adjustment all over the screen.

Usually the customer mode works ok--if you find red or blue will not adjust somewhere you have a problem-that aside tell me what you are trying to acheive?

Why does the power light flash on my tv after 15 seconds when i turn it on for sometimes 2 or 3 days.


Hi, this is heat related. you will need to replace the fans in this unit. this will fix this issue. also, inspect the ballast in the lamp area. if it clicks when you are powering up more than 3 times, the high heat may have damaged this circuit that provides the power to the lamp.

Toshiba 55hx70 projection tv problem


How many times does the light blink? It should blink a number of times, pause then blink the same amount then pause. Try to count the blinks then let me know. Also how long does it run before shutting down if any?

Blinking power button


You likely have bad convergence output IC's that have caused one of the supply fuses to blow. This repair will have to be performed by a qualified technician. If you were in our area and has us repair this the total cost of the repair would be about $340 if I am correct about the cause of your problem.

check all the fuses. Its easy to mis the 2amp pico fuse mounted near the middle of the power board. When this fuse opens, the red at the top, especially at the left side of the screen, will not adjust enough. Be sure to use new heatsink compound behind the ic's Shutdowns,are usually,not an easy repair Good luck
