Hi
Thanks for using FixYa. From what you have described it seems to be an issue with Y board however, Z and the logic board should also be checked. These boards are located on the right side of the unit and to check them you'll have to open the back of the unit. Once you have opened the back also check for any blown/bulged capacitors. All this is only recommended if you have electrical expertise & know how to solder/re-solder components as these units contain high voltages even when in off position. Please accept the solution if the issue is resolved or post a comment for further assistance.
Thanks Rylee

I'm back again after about a month away. Back to my problem, horizontal lines and/or interference make watching my Samsung 52" flatscreen impossible. TV is 5 years old. A limited time recall has passe


The TCON board can give you both Horizontal and Vertical lines, it is real easy to fix and fairly cheap. The most I have had to pay for any TCON board has been $45 plus shipping. Mostly what goes bad on these boards are the IC, a part that costs around $5.00 but requires micro-soldiering experience and tools.

LG LED TV 42 inch 1080p 120hz horizontal lines and upside down picture


Sounds like a main digital processor board fault. In other words, its main board should be checked. This is a very skilled work, and a normal user can't do it with ease. Contact any expereicned service technician. Products powered by electricity should be serviced or repaired only by experienced professional technicians. Any attempt to service or repair the product by anyone else could result in serious injury or death. If you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electrical shock. Instead, contact the nearest service centre.

Vertical lines on my 40 inch lcd mitsubishi hdtv 1080.


I assume your Misubishi is not close to anything electrical. However, it sounds like you have had an interference for some time. This will ineviteably cause the HDTV LCD to collapse. LCD's don't respond well close to heat. Is there a vent close? LCD's do well in a properly vented area but with all this said.......they will pick up interference from anything electrical. A few questions to ask ones self........are there any wireless devices or chargers close to the LCD? Might there be an oven, a/c unit or other wiring with 220 volts anywhere close to the LCD such as in the wall?
The Mitsubishi LT is a very reliable, multi component ready set that allows great viewing with surround sound. However, stop and think about this interference. It is not something in the unit. It is an interference. Look hard and when you've discovered it.....you won't believe how crystal clear this set will be.
Let me know what you find...Thanks for using Fixya and add any comments that may help us help you.
