Question about Vizio VU42L 42 in. LCD TV
I checked all connections and the P/S 5, 12 & 24 Vdc supplies seem to be fine. Both Inverter boards are humming as normal. The power sw works to turn the unit on and the main relay clicks it in but said sw won't turn it off and the remote does neither. All the transistors on the board seem to measure as normal with a diode checker and the heat sink rails run at ~160VDC. The LED back light glows as normal. Any other troubleshoting tips will be appreciated.
Well,mike seems youve done everything to your TV and nothing happen..Try to reset the system of your TV.On the main board there is a small button just press it to reset your system and see if your TV will work again tnx.
i hope i help you..
please rate my help...
