gb5108 apex horizontal lines

[nowrob3]

i have had this apex gb5108 tv for serveral years, and just a few weeks ago all the color on the tv has become 1 horizontal wavy line. i can still heard sound. i have read serveral other places blame it on a semiconductor. what could it be? i dont kow where i would buy a semiconductor. any help i give thanks to.

Sounds like you have a vertical failure. I'm assuming you mean the set set has 3 colored lines running horizontally across the screen which indicates a vertical circuit failure. The vertical IC is a semiconductor, however additional parts need to be checked. If you cannot locate this part on the chassis you may want to turn this over to a more experienced person.

This a easy problem to fix. You say it has a thin line accross the center. Change out IC N301 it is a TDA8351 and it crosses to a NTE7156. Also change R370 it is a 1W/1 Ohm Oxide Metal Resistor
R371 it is a 1W/33 Ohm Oxide Metal Resistor and
R380 it is a 1W/1 Ohm Oxide Metal Resistor.

Be very careful not to short any pins on chip with solder when re-soldering, double check all solder joints for shorts and correct before turning set on. This should fix your problem with the vertical collapse.

In other words, your vertical IC crapped out.

WOW! I AM HAVING THAT EXACT SAME PROBLEM... I WOULD LIKE TO KNOW THAT ANSWER TO THIS AS WELL.
