I have a Samsung 32" LCD tv, recently the picture starts to flicker before going completely black after 5 mins, however the audio is still there. Anyone knows what' the problem and how to repair it.
I will first resolder all ic`s and connections,especiall on the crt board,clean around the flyback at the abl circuits,check for open or changed valued resisters in abl circuit and the video b+ on the crt board (usually 165-200 volts) check also the screen voltage (G2) volts,should be around 250 - 400 volts.

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.
your picture tubes is going bad. i've had 5 yes 5 of these tv's replaced by samsung/bestbuy. i've kept buying the PSP (product Service plan) now my most recent tv is doing the same. samsung no longer makes the picture tube for this model. i've already called them. it was a nice tv. i've gotten about 6 months out of each model. I'm moving on the LCD, nice rca 32 inch HDtv model at walmart for less than 500.00.
