White line in middle of screen on a cx32h60 toshiba tv


The vertical sweep output is absent. Check its vertical output section circuit for the fault. Check all the solder terminals of that section, and resolder them by applying a little more solder. Take special care to the solder terminals of the vertical output IC. If these do not help you, check and replace the vertical output IC.

Magnet from speaker caused white lines at the top of screen on 27af45


Hello
The faut to your TV is with its vertical output section circuits. Vertcal lenearity may have changed duse to defect of some electrolytic capacitors used at that section. If you have enough knowledge in electronics and have experience ins tracing the circuit, just open your TV and locate the vertical output section. The section to your tV is built around and IC [la78041]. This IC will be screwed on to a metal heatsink to radiate heat from it while it works.
Replace the capacitors [C407, C406,C409 & C413]. Adjust the preset resistor [VR401-1], a little bit. It is the vertical position adjustment preset.
If you want to get your TVs repair details, which includes its schematic diagram, printed circuit board and component placement details, adjsutments to be done after repair etc: you have to purchase one among my Toshiba servies advertised on Fixya. I can't send any PDF files by this window. OK.

Hello, one of possible solutions is to replace capacitors (10uF/50V) on HYPER (PD0246) module. Please ask the tech to check/replace them. If you need more info please advice.
