Sylvania 32" flat screen has horizontal lines across 1/3 of screen, how can I adjust/fix it?
Can you please get me the model number off the back of the TV?
How long have you had the set for, and when did the problem occur?
Additionally, what is connected to the TV for devices (DVD, cable box, etc.), and do you have the same issue regardless of which INPUT you select?
If you bring up the TV's MENU, does the MENU appear over or behind the lines?
Model # XXXXX
Can you please reply to the rest of the Info request so I can assist you?
owned 1 1/2 yrs. has no attachments...
lines appear in FRont of menu ,owned 1 1/2 yrs. has no attachments...
Thank you for the reply.
Is there any buzz, hum or clicking sounds coming from the set?
Is the power light lit steady or blinking?
no sounds whatever and power lite is steady
Please disconnect the set from AC power, then press and hold the power button on the TV itself (not the remote), for 10 seconds. After another minute, plug the set back in and press power once. Do you still have the same problem?
Is there any change once you've tried the steps above?
no change, sorry
Unfortunately I do not have good news for you. There is no sequence of buttons you can press the reset the TV, and it will require circuit testing and component replacement to operate properly again.
There are basically three problems that would cause this, the Power Supply, the T-Con board, or the LCD panel itself has failed. Voltages need to be measured at the power supply outputs, using a DMM with nothing connected to it but AC Input. If the readings are proper, then the other boards need to be connected one at a time, until one causes the voltage to shut down at the output. Price to replace the power supply is around $150 parts and labor. If the supply outputs power with all of the boards connected, then the T-Con needs to be tested. The T-Con will run you around $100 to have replaced. If the T-Con tests good, then the LCD Panel has failed and will cost you more than a new TV (around $250) to have replaced and it is not cost effective to repair this set. I wish i had better news on this set, but the symptoms you're having indicate a failure in one of the components responsible for powering, and processing the LCD panel itself (including the LCD panel).
If you do not have experience testing live voltages on a circuit board level, then I would suggest using the link below to locate a tech in your area:
