Turned on my set that had just been working fine and there is no picture or sound. Slight Electrical odor when turned on. Also a "chirping sound about once a second. LED DP37 blinks in unison with the chirping sound. What broke??

Re: No Pic or Sound
It sounds like a defect in the horizontal drive or HI voltage circuit. Could be the Horizontal output transistor , and /or the flyback transformer, a short in the scan derived power supply on the output of the flyback transformer. If your not aware of the HI VOLTAGE issues and have soldering experience you should seek a pro to assist ya in this repair. If you do have the experience, get a schematic and start with the hi voltage circuit. Good Luck

I have same problem with mine, the power button turns red (as usual) but no picture. When i turned mine on last night it made a crackle noise and thats how it all started. I can even hear the normal sounds it makes as if it were turning on, but still no picture. Its a great tv I would hate to throw away. I want to fix it myself any help would be appreciated!
Had the same issue sound but no picture, try wiggling the connections to the back of the tv, if that does not work try using a different hook-up, I ended going from the component jacks to the DVI hook-up and this took care of the problem, hope this helps!!
You can get the replacement Flyback at the following link, and they provide free instant messageing tech support to take you step by step with the replacemnet proceedure. You need phillips 32942 flyback, its listed in their flyback catagory. http://servicemanuals.vstore.ca/
I would call PTS at 18008447871 and find out how much a new deflection board cost, because by the time you find out what is wrong and start replacing things you will be out more money. Not including the smell that means probably the flyback was burning or arching.
Did you have color problems in past? Most of these sets have convergence problems. Amps goes out. But you should have seen some type of distortion from color, red,blue, green. If no color problems then maybe vertical ouput out or horizontal output bad.
