Hi,

Pls confirm the exact model number of your TV. Additionally, it would facilitate if you could also determine a Chassis Number if any.

If it were a conventional TV, then initial suspect would be a capacitor at the vertical section is about to fail. This is relatively an easy and cheap repair. Nonetheless, this of course would require a fair familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron. It would be to your added advantage access to a service manual or at the very least a schematic diagram with voltage readings. Should you be uncomfortable performing a DIY (do-it-yourself), perhaps your best bet would then be to seek the services of a qualified professional. Or consider the alternatives as proposed by the other experts.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

This is the conversion IC , it is most common in all projection TV's , the IC is an STK type it will correct the problem
the IC is only about $30-$40
but to have a tech come and replace that IC is about $300 or more

This is a complex repair and the exact cause cannot be determined with conducting tests and a manual inspection. If you have no experience with TV electronics or repairs, I would never recommend a DIY. Trying a DIY could, infact, actually make things worse in the long run.

In my honest opinion, it is better to send the TV to Mitsubishi and get it serviced. They will stand behind their repairs. If you feel the cost is unjustified, then best bet is to purchase a new set. In this case, you can attempt a DIY, if you feel inclined to do so..

Cheers!

I don´t think so. You have a technical problem. Is your cable operator working ok?

The PIP board is small and square and stands straight up on the main board. It plugs into a socket. It also has a ground wire that has to be unsoldered to remove it from the machine. It is located essentially in the middle of the main board near the rear of the set. Sorry I can't describe it any better. Go to http:\\www.tritronicsinc.com or call 1-800-638-3328 for parts. Thank you!!

1 inch lines on top and bottom of screen


Is the picture overall too small by 1 in. on top and bottom? Or is it cut off by the lines?

If it's too small, look for an adjustment labeled Vertical Height. This may only be accessible internally, it's normally a service adjustment, not a user adjustment.

Your problem is a vertical deflection issue, either an adjustment or the vertical circuit requires repair by a technician. In the latter case, electrolytic capacitors are a likely cause.

Horizontal Lines


sounds like you are seeing retrace lines. you will have to adjuste the screen control. (it would be like a master brightness.) you will have to removed the front bottom plastic from the tv, look for 2 to 4 screws. then gently remove the front. sometimes the also add velcro to help hold it in place. now you need to remove the small plastic or wooden panel/door. in the upper right side you will see a small box with 6 controls.i do nor remember if the top 3 controls are for screen or focus, use a flashlight it is marked on the box which is which. adjusted the screen control to the left slightly to decrease the color you need. the green is the center control. like you said it is more noticable on dark screens, so try & adjust it in a dark romm with a drak seen. good luck.
