Default Re: Telefunken 48" TLEDD-48FHDA not starting up.

for simple test, use 3 diodes in series(1.8v drop) form pin 4 to pin 5. (anode pin 4) pin 4=5v, pin 5=3.3v. (1n4007). if cpu overheat, most likely original problem. longest one running +- 1 year(still running but for safety i replaced diodes with mini-adjustable regulator). china chassis collection (4 circuits) was downloadable from kent liew website.
