LCD TV thats needs to warm up for a couple of minutes	Can't Post

When I turn my LCD TV on in the morning I get a high pitched warbling and a screen that fades to a black screen. After a couple of minutes everything is working fine and last for the rest of the day until I turn it on the next morning. Any ideas on what might be the problem?

My TV is a Westhinghouse LTV32W4HDC

A number of electrolytic capacitors in the set (most likely on power supply or inverter boards) are pregnant?

I agree. Caps can go all at once, or slowly. Yours are going slowly. Not all LCD TVs have fuses on the primary. Capacitors work better when warmed up, but they go on strike when things get too hot.
