Where is the verticle output IC on my 52 inch rca projection tv


if you remove the rear panel you will see the board on the far left has a large transformer with a large red HV cable coming out of it. Thats the flyback. Now look to the right side of that board in line with the flyback. The aluminum heat sink with the fins has the verticle IC. Its the first heatsink closest to where youre looking on the right side of the board with the flyback.

When I run the Touch Focus , it ends Touch Focus Error, and the Red Verticle line does not move , the Horizontal is bent .. now tv is fuzzy?


This is a convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually charge between $200-$300

Hitachi projection tv, 50ux26b, picture jumps after it has been turned on ~20 seconds, then it settles down and works fine. advice?


The two most common problems with Hitachi projectors are in the verticle sweep circuits or the convergence. Both can cause that symptom. The good news is it is likely to be bad connections on the convergence power pacs or the verticle output IC or both. If bad connections are observed it is a good idea to resolder all suspected bad connections in general. There is a remote chance that the problem is out of tolerance filters on either the main sweep board, or a problem on the PIP module circuits. Consult with a repair specialist if you need more information.

Followup question on the advice to pass on the $100 tv.


no its a DLP they are having some troubles with the dlps losing signal due to the digital board. verticle ICs only effect CRT projections by making the CRTs shutdown . Dlps are all controlled by the digital board. They are very expensive when you can find them. They are usually over 800 and need to be special orderd. I would pass on the TV. You can buy one cheaper than fix that

Toshiba TV with only a horizontal picture?


You could have a simple loose connection on the vertical output IC . Sometimes you can tap the board and the picture will fill out . Or the IC could have failed . It will also take out the resistor that supplys the voltage to the vertical IC . If you take it apart to work on be careful as you can be shocked if you don't know what your doing . Most repair shops charge $50 to $80 to repair . Good luck

Trouble!!


Most of the time when theres no picture on a mitsubishi projection set, theres no verticle sweep. Most likly cause is the verticle output IC or the b+ feeding the IC or Both. This is not a consermer replaceable parts. It could also be the PIP module if the set has one . Remember these sets have alot of hi-voltage even when the sets unplugged. Good Luck

This symptom seems to be a vertical Sweep fault cause what happens is theres a protection circuit in this set that activates when it sees theres no verticle sweep, it shuts off the picture on the set so that the tubes dont get lines burnt in the middle and become damaged. If you know your way around a TV set then you could locate the vertical output IC and resolder all its pins first as well as anything else in that circuit that looks like a cold solder connection. Then i9f it still does the same thing I would just replace the verticle output IC as well as the B+ supply capacitor off the flyback xformer for the sweep dirived power supply. Now if your not knowlegeable about these HI VOLTAGE circuits my advice would be do not attempt the repair yourself as you could get hurt and /or cause more problems with the set as there are no tubes in this set to test except the picture tubes. Contact Mits. at this #800-332-2119 or look in your owners manual for a contact #. Good Luck.
