Question about Hitachi 53UWX10B 53" Rear Projection Television

1 Answer

Hitachi 53UWX10B Big Irish, Thank you for your respond to my earlier posting. I did change two IC's and 6 1watt resistors on convergence board. This didn't solve the issue. I'm still getting colors pulling to the right of the screen almost out of focus then the screen goes almost black & white with clear picture. After few second then the picture goes back to color and normal viewing. Obviously this happens when the television gets warm or being on fo 10 to 15 minutes. Thank you, Armenian

Good Day, Armenian;

You may have CRT Coolant on one the boards. LOOK very closely for shiny spot on any of the boards. WHY? Because you are saying the TV is having multiple problems. Let me know.
Good Luck, big IRISH.

The colors in my tv are overlapping and picture is wavy that cannot be solved with adjusting the manual converge function and got worse when I tried restore manufacture settings


Bad STK392-120 convergence IC. You need to replace 2 both and also check feedback/return resistors. Convergence IC is located on large signal board with a big heatsink. :)

Convergence IC + Resistor swap = Blue light clicking noise


Good Day,
It sounds like you may have slightly diconnected a cable. Look for the large RED cable/wire that goes to the Blue tube and make sure that they are very secure. When doing this make sure the TV is off.

Good Luck, BIG IRISH.

Problem with TV screen?


Good Day, deon453;
Sounds like a convergence problem.
Corrective Action: Replace the defective Convergence Output IC Part Number 23905094 (STK392-110) using the revised “T” version IC Part Number 23135090 (STK392-110T). When Convergence Output failure is
detected, it’s recommended that both IC’s be changed to the “T” type IC
version.
Good Luck, Big Irish.

Red will not line up


Good Day y'all;

First of all if the lights are on, that's good, the red light,LED's, indicates that there is power to the power regulator IC. The green lights, LED's, indicate that the DC voltages are present for those particular circuits. ALL GOOD! If off bad!
If after replacing the IC's with the 150's and still have color shift and all resistors are within 2% tolerance and adjustments were made properly. The digital convergence board may be defective.
If the picture is bleeding that normally is a gassy CRT, picture tube, and the bleeding changes with the brightness levels. You may try to rejuv but that may short life the tube.
Good Luck, get back if you want more details, Big Irish.
