I just replaced the lamp in my tv, it will work fine for 10-15 minutes, after that the picture will start to flicker and then just go out completley and th lamp light will blink on the tv set, what could...


My 50HM66 did the same thing. Try putting a fan to the side of the tv so it blows cool air around the back. I also removed lamp and vaccuumed as best I could. I think this is an overheating issue with the tv.

I have picture but no sound when connected thru hdmi using a panasonic blue ray Dvd player. It is working fine with my 42 inches sharp lcd.


Be sure you are not trying to use 1080p/60 from your Blu-Ray player to your Toshiba. You should connect the player to the Sharp, then set the output to 1080i... then move it over to the Toshiba.

You have bad solder connections in the deflection circuit. Call a good TV tech unless you know what you are doing. You could get an electrical shock from a charged capacitor.

The problem you are describing is called loss of verticle deflection. You will find this will require diagnosis and there is no simple answer to this repair. Most likely there will be either bad electrolytic caps or bad vert. output IC in the vert. circuit.

Toshiba 52 inch flatscreen


I have just completed removing tha base from a Toshiba 52 inch HDTV. There are 5 screws in total. Three about 8 inches form the base and another 2 about 4 inches from the base in the arrangement shown below

(X) is a screw
(l) center line

X X X 3 screws 8 inches from base
X l X 2 screws 4 inches from base
______l______ The base

Keep your feet clear as your undoing the last screw..the base slides out vertically downward and weighs about 10-15 pounds so keep your the toes, fingers etc safe. The risk of being sued may explain why Toshiba didn't this publish in the US manual.

yes it could ba the cable itself even, but i suspect more the tuner circuit or tuner itself may have bad solder connections. Here is another test for you to try, plug another dvd or vcr, or xbox etc. into the back, using one odf the inputs. See if this works like the built in dvd. if so it will be more likely bad connections in the tuner or surrounding circuit. good luck.
