Resolder the vertical deflection section. Change pump up capacitor if it has one...100uf is a typical value. Is the vertical output some flavor of LA783x ?? May need to replace. A model # would help.

SOURCE: screen black - power to tv is good.

Since the set is only 8months old, it should still be under warranty. Please contact the manufacturer for directions on how and where to get this serviced. This should be fixed at no cost to you.

Hi syzonker
Before you replace the power supply , check for swollen(rounded top)capacitors.
Also check and replace C126 47mfds/50 volts
And C520 1000mfds/16 volts
good luck and let me know if you need further help

Flickering screen


Two models of the 46 inch Sony Bravia have a screen flicker problem. On my 2008 model, starting from cold, it lasts for 5-10 min, on LHS of screen. The Telefix tech who visited said this is common with these models (46in only), a new panel is needed. Sony provides warranty on this fault for 3 yrs, so you do not need extended warranty to claim. Discuss your case with Sony or Telefix.

Flickers on cold startup after 5 min then goes away in 2-3 min.


I had same problem. Tech's said the power was noisy. I cleaned up the power but the TV still did exactly as you describe. Problem will progressively get worse with longer bouts of flickering. I was under warrenty and sent the TV back. After 3 months I am still waiting for a repalcement.
