Repairman is trying everything and I'm getting scared
Picture is terrible, 3d effect, and wavy. Repairmen changed the ,"ic's", i believe,and now we have no picture. Then he said I had some bad resistors, he showed them to me, they were burnt, and he replaced them. Still no picture. 3weeks now and he is telling me that he is having a hard time talking to Hitachi, via the phone, and e-mail. So I don't know what is going on. My concern is this. When he changed the resistors, which were green, he replaced them with a blue smaller resistor. Are these the same resistor or was he trying to slide one by me. I'm a nice guy, but when I ask him questions he tell's me different things each time. So if you have any suggestions I could relay to him i would appreciate it.

Replace convergence output ICs in your tv to fix this 3D look picture, it happens due to convergence output chips failure. Local tv repairman will fix it for you if you have no prior experience of part replacement in tv circuit board with proper tools.
If you have the ORIGINAL remote, you can access the diagnostic computer built into your TV (neat, seems only SONY has it ). Download the manual (google it, it's out there!) and follow the instructions. Universal remotes WILL NOT WORK. Good luck, hope this helps.
Generally speaking a convergence problem will show up as a picture that appears like a 3D image with a bowing from the top and bottom. If this describes the problem, then try resoldering the pins on the convergence ICs. If that fails to resolve the problem, replace the ICs. These are large black ICs attached to a heatsink that should be marked STKxxx.
Keep me posted.
I am sorry about the late response. With the site changes, the questions aimed directly to me were no longer on the initial page and I was not aware of this.
This is a convergence problem. Ther are either bad connections at the convergence ICs or the ICs are defective. If you can solder, you can repair this yourself. Try resoldering the pins on the ICs first. If that fails to resolve the problem, replace the ICs. These ICs are large, black and attached to a heat sink. They should be marked STKxxx. Figure on $20 for each one. There will be 2 of them.
Keep us posted.
If you do not have hand soldering skills or know how to use a multimeter, I would suggest to replace the whole assembly. If you know how to solder you can just replace 2 ICs that are mounted on the big black heatsinks and possibly 1 or more resistors. Click here to find the entire assembly for your TV. Good Luck.
you have to replace all 3 ic's and 2 are stk 392-110 and the 3rd one is stk 392-150 they are located on the extreme right of your tv on a long heat sink all 3 are located there.You can get replacements as well as free tech online support at http://servicemanuals.vstore.ca/
You do not need to change the CRT's or lenses. The failure on this TV is the convergence ICs that became defective.
If you know how to solder, this should be an easy fix for you.
The IC markings are STK392-150 with locations IC1502, IC1506, mounted on a big heatsink(s).
If you want to change the complete assembly, you can check this link and ask them if they have the assembly where the STK392-150 ICs are mounted.
