I'd be curious to hear where do the other guys found those 12V/500 mW.

I am holding in my hand a transient suppressor from an LCD TV power board with two lines on it - the first is saying LT7232 and the second is P6KE120A.

I can't find a reliable reference for LT7232 anywhere through Google, however P6KE is a well known series of transient suppressors and I am ready to bet this is the proper component here.

Hope this helps avoid confusion.

It sounds that the main power supply section to your TV has the fault. The horizontal thik lines that appears crawling down across the screen should be of video 'HUM'. Have you replaced the main filter capacitor at the power supply section? If not, replace it along with the main rectifier. The AC power is rectifed by a bridge and applied ot this main filter capcitor. It will have a capacitance value between 120 to 350MFD 450VDC. Check this section. Measure the rectifed DC voltage acorss this main filter capacitor. It should be around 350VDC, if your home power supply line is 220VAC. If it is 110AC, this DC voltage will be around 165VDC; and it should be. If rectified DC voltage found lower than the input AC voltage, replace the rectifier bridge. In some sets, this bridge section have four diodes. Some other circuits, a bridge rectifier stalk may be used.

between image controls, (contrast-brightness-colour), Check the "colour" setting. should be near the middle of it's way.

if an automatic scan was performed before the event, please start it again, but assure proper country selection when asked (or better, check if there is a country selection menu and have it set to your country BEFORE starting the autoscan.
