I have a Hitachi 60sbx78b rear projection tv when I moved the set about 60 feet to a new room.when i turned it back on I now need 3d glasses to watch it the colors are all out of aline and the green line...


Check your owner's manual and see if there are instructions for setting the convergence. This lines up the different color guns so that you don't need your 3D glasses. If setting the convergence doesn't work, you may need new IC chips. Good luck!

Picture looks like 3D without the glasses


This is a convergence prioblem that can be as simple as poor solder connections at the convergence ICs or defective ICs. In any case, to provide details, I will need the model number. Can you please update this and confirm that the model number is: 60PP9202? ALso, please indicate whether or not you wish to attempt the repair and I will provide additional instructions as well.

Thanks,
Dan

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

Wide screen t.v. picture problem


You have a convergence problem. Here are some of the most common symptoms.

Screen looks 3D
One or more colors can't be adjusted when using the convergence menu.
Screen is bowed in but stationary.
Here is a quick test....
Using your original remote go-to the tv settings then goto the convergence section.
Try to adjust the red and then the blue convergence.
You should be able to move them up, down, left, and right.
If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

You need to replace the convergence chips and convergence resistors.
Check the site www.TvRepairKits.com. They have put together a kit for your exact model. The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc. Everything you need to fix it yourself.

Picture is warping and colors are seperating giving a picture that looks like a 3D picture without the glasses


you need to replace both convergence Ics. Post the model number of your set and I will post the correct IC numbers as well as alink where you can get replacements with free instalation instructions. Respond to this same post so I will have access to your symptoms when you post the nodel number.

Problems after new ic chip install


Did you check for open resistors in the convergence circuits? Often that is what happens when the old ICs wear out it will cause a couple resistors to burn open, and they show no outward sign of being bad. Also double check the IC pins connections for solder bridges thats another common problem, I always use a magnifying glass to double check my solder when ever I do convergence or any IC work where the pins are close. But with the streaks youre describing I would think maybe resistors.

Like a 3D Movie


your convergence has gone out....there is possibley two ic chips that have failed. It might be some fuses but generally if they go the chips are the cause. on average a 300 dollar repair with parts and labor. first try to autoconverge the set if that dont work it will be the chips
