You will need the service manual with the alignment proceedures in order to be able to get it back. And usually the problem with the older sets are that the adjustment pots get wore out. You can do it if you had a pattern generator, but short of having a generator you will need the service info that will explain how to make a template for the screen and then adjust all the parameters for each color. Its a very involved process.

OLD Hitachi 50EX13K rear projection TV now has bow shaped picture


Your convergence ic's have to be replaced along with checking all the bias resistors for exact value. Easy for me! I don't know what your electronics background is?

Please tell me the correct way to clean the pleziglass screan on our new to us 2 yr old 52" RAC Big Screen TV


The best way is to use a soft,lint free cloth and get some specialized screen cleaner just for TV's, LCD monitors, ETC. Never use widex or any of the ammonia based cleaners. Have seen folks make a real mess of their screens.

Ok thanks for the info Now this is an indication of convergence issues(3d effect) the bowing issue idicates a complete loss of convergence power. which possible could be the convergence ic or the actual power feeding them. im feeling like it might be the ic overheating these get very hot. now the bad news. this is a set that is very difficult to work on. Rca has compiled a long list of problems with this set. getting to the chips is a chore. i cannot recommend repairing this set. I know no one likes to hear this.

there are several rca issued suggestions. the top one isChange C19542 on the Digital Convergence PCB from a 10uF 63WVDC capacitor (214698) to a
470uF, 25WVDC capacitor part number 214746.
Also change the 24V zener diode CR19720 (226446) on the Convergence Power Supply board to a
30V 500 milliwatt zener diode, part number 231211 this
but as i said this may or may not be the best solution
