Hitachi 60sdx88b convergence problem IC

I had a problem with convergence a couple of years ago and the repair man changed out the IC (interconnectivity Chips?) and he left them behind. I am having convergenc problems again and I called him and he said it was most likely these IC's again and would cost about $300 to fix. I pulled the back cover off to try to find these chips but I can not see them anywhere. My only thought is that they are inside of one of the metal boxes connected to a circuit board. Can anyone tell me where exactly they are located and how to take them out to change them. I am pretty handy and my tv is not worth that much now so I would like to try to fix this on my own first.

When you pull off the lower half back of the t.v. the grids are in 3 sections (boards). Look at the right board the chips will be right front corner , they are attached to a heat sink ( big silver thing with cooloing fins) You must disconnect all wires ( color the connector and plug with different color markers so it is easy to re-connect when done.) There are sites that show step by step pics how to do

Just keeps flippn like the vertical hold not workinright but not with every channel

Have a repair guy in and have him look at your Horizontal circuitry and replace a few Transitors and Maybe (don't tell him) a IC.
If you tell him... he will change it and charge you alot. The changing of transistors 50-60 bucks
IC's 100 - 200 bucks
You see why (Don't tell Him)

I purchased a tv repair kit and replaced the convergence ic chips to fix my convergence problem. put everything back together and now, no picture. I tried magic focus and it works great, the colors are...

As per statement, "the magic focus works great, the colors are bright and aligned" it means the tubes are working need feed a signal to see the picture...the tv video goes muted without signal

Red horizonal convergence tilts instead of adjusting evenly.

For your hitachi unit one of the convergence IC is bad along with couple of low value resistance on
the convrgence board.

Good luck

most of those have screws down one side of the heatsink going into the PC board and other models you have to unscrew the ics through the fins on the heat sink.

Red deflection is way off, picture scrunched into top right corner

call 800-648-6657 order part number CZ01341. This is the convergence output ic. You will need to replace the red convergence output ic IK04.
