Have TV Questions? Ask a TV Technician
Hello and sorry you're having problems. In order to determine what's caused this, and the next steps to take- I need to ask you for more info.
1) How long have you owned the set for and when did the problem occur?
2) If you press MENU on the original remote, will the MENU display clearly?
3) What color are those lines and how thick are they?
4) Is the audio on the set still working normally?
Please reply back with details and we can proceed.
Thank you for the reply. If nothing at all will display on the screen when the set is powered up (no welcome screen, no MENU's, etc.) then this indicates a failure within the TV. The native MENU's supersede all connections and settings, and when we cannot view them, we know the issue is indeed internal. There are only two possible causes of this problem- one is the T-con (LCD controller), which is a replaceable part, and the other is the LCD panel itself (most likely cause given the lines are multi-colored). Unfortunately the only chance of repairing the set is to purchase and replace the T-con board and hope that it clears the issue. Since it could be caused by either the panel or the T-con, and there is no way to test either part without the other- we simply have to replace the T-con or replace the TV. The cost of a new LCD panel is 80% of what the TV cost when new and the set would be not repairable in that case.
Unfortunately I'm not able to find the T-con board being available for purchase for this set:
If you're looking to DIY repair the set, then you'll need to use that part number and search used/pulled parts sites like Ebay and Amazon, or Shop Jimmy and replace the T-con.
However if this is not something you're comfortable with, then a shop will charge close to $150 parts and labor to swap the T-con- but these symptoms do point more towards a failed screen than anything else.
Given that I would consider putting that same money towards purchase of a new set, as a brand new 26" LED TV can be purchased for around $180 these days.
Other than that, I'm sorry for the bad news here and wish there were a quick fix.
