Turns itself off.Also when you change channels, picture comes in great with plenty of contrast, then searches 3 times and then contrast is very dull.Voltage is constant at 128 volts.I Heated and flexed the chassis & makes no difference. Seems like set has it's own preset timer. When it shuts off you can turn it right back on and start all over. Any help is greatly appreciated.(I don't have a schematic) TIA Richard La Placa Continental TV 312a Park Row Chestertown, Md,21620 Fax&Phone-410-778-1113 continentaltv@xxxxxxxxxxx _________________________________________________________________ STOP MORE SPAM with the new MSN 8 and get 2 months FREE* http://join.msn.com/?page=features/junkmail ------------------------------------------ Submit A Repair Tip For Everyone Here: http://www.tech-assist.org/secure/tip/main.html ------------------------------------------ To REMOVE your email address, click here: http://www.tech-assist.org/unsubb.html To CHANGE your email address, click here: http://www.techassist.net/forms/change.html
