Hitachi 53FDX20B Rear won't turn on and LED's Flashing


I believe they are the voltage supplies for the TWO convergence IC's that this set uses(either STK-392-110 OR STK 392-150---THEY are interchangeable--but the 150 is a better device)

The easiest way to prove if this is your problem is to locate the two chips (black--2 1/2 inch wide X 1 1/2 inch tall with the STK number printed on them IN WHITE)

If someone unsolders all 18 pins on each chip--see if the set will turn on with them out of the circuit (you do not have to remove them--just unsolder both---If the set comes on the convergence will be very bad but you will know one of the chips is bad.

Also if you look at all the resistors around them (most will have location number RK46 etc) see if any of them are discolored or burnt. You find a burnt resistor and it is a sure bet onE of the chips is bad.

BOTH CHIPS NEED TO BE REPLACED!

A pretty easy repair if you have good soldering skills and I can tell you what you will need to do the repair.
If replacement of the chips fixes the set it just needs to be adjusted with the Hitachi remote and should not have this problem again for 5-8 years.

53FDX20B NO PICTURE AND SOUND


It powers up but no picture? In my experience with Hitachi TV's this has been an issue with the convergence IC's failing. You will need to have a technician replace those if needed.

Yellow bubble coming down from top left. Auto


Commonly the whole board is not changed for this problem. What needs to be done is to have the convergence output IC's replaced. That is not an easy task. Although some do-it-yourselfers pull it off. The job can be done in your home by a technician and usually runs around $200 to $300 total depending on your location. Prices are higher in large metropolitan areas.

Age of tv?


I purchased mine from Circuit city back in spring of 2002 as a display model that they were no longer selling. So I would assume 2001 which would be almost 8 years old. Excellent tv!
