TV started to require multiple button bushes (on the front panel) to turn on. It worked fine via the remote. Sudenly it will not turn on at all. There is a high pitch whine coming from what I beleive is the power supply area.
I took my multimeter and measured around the CPU and noted that no voltage is present on the VCC and VSS on the chip. I can not seem to find a service manual to show me a schematic, so it makes it difficult to isolate the problem.
The front panel switches and the IR receiver connect directly to the CPU I/O so I would presume there must be voltage always present at the VSS/VCC pins for the power to work.
Any ideas for me on what I can check, or further information I can use to fix this TV?

On the remote that came with your TV, press the Display button, which is directly below the Volume Up button. Pressing it once displays the channel number and time, pressing it twice displays the channel number continuously, you must have accidently pressed the Display button twice. Just press it once more to remove the display.

Hi Hfrohman, This may sound crazy, but, press and hold the power button on the TV while unplugging it, continue to hold power button for 60 seconds or more. Release it and plug TV back in. Sometimes that will clear the settings.
It isn't a transistor, It will be an I.C. with a part number that
probably starts with an LA_ _ _ _ . It will be on a heat sink and
be in the vicinity of the connector going up to the yoke. Try
replacing that. But first, check all the electrolytic caps around
it for testing dry (sorry - takes a special meter to do it in circuit)
or just replace them. May have lost power to the I.C. as well.
Look the I.C. up in the free NTE crossreference at nte.com get a
diagram of its pinout to find what pins the power and outputs are on.
I would suggest getting the Phillips Digital 5 Device remote Model PHDVD5, I have one of these, and I have yet to fond anything this universl remote will not operate, it is outstanding! you can get this remote at a local WalMart store, thats where I purchased mine, goodluck:)
