Question about RCA HD56W66 56" HDTV
TV does not start it blinks several times and does not turn on.
Any idea if its a typical problem with this TV or where the problem could be? The power supply checks out and the Horizontal output too.
This a very common ocurrance among these set. I Deal with the rca itc222 chasis daily at the shop. I have found these set can be very tricky to troubleshoot. These set have a microprocessor that will shut the set down for 1 of about 25 different reasons. technicians have a device called chipper check that can read errors that the processor generates. i have found that the majorty of problems are high voltage like the hot and flyback. or the tubes. When you say "power supply checks out" what do you mean. There is a slight chance it could be bad data in eprom too. Does the set make any noise chirps, are there any smells. what was the set doing when it shut down. give me all the details and we will see if we can help since you no what "horizontal ouput is I ASSUME that you have some eletronic knowledge.
