Question about Hitachi 50DX20B 50" Rear Projection Television

Open Question

Not powering up

I have this Hitachi 50DX20B rear projection TV and it has worked perfectly until recently. Turned it off one night and the next morning it would not come on. Unplugged it for several hours and plugged back in and power light would come on for just about 1 second then back off - never turning tv on. Then it would not come back on unless I unplugged it for several hours again then it would do the same thing - just turning on the power light for about 1 second or so.

Both of these problems sound like the 2 convergence ic's. Not something the owner is really able to repair. You'll need to call a svc co.

Good Day, you all;

The front panel light on Hitachi TV does not really tell you much. To see what the TV is doing or better said NOT doing is remove back from the set.

If you are not a technical type person, it would be better to consult an authorized service center, but if you are perform this; 1. Remove back
2. Observe led and notice which once light, there are as many as 9 LED's.

Now that will tell you what area of the TV's circuits are to be concerned about.

Let me know, Good Luck, big IRISH.
