53WUX10BA no power/sound/video but power light is on.

Could not find E907. I looked at the circuit involving DP23 and found that FP05 (3amp) is open on the DP1X Deflection board (right in the middle of the board).

I will test everything in this circuit and replace FP05 if everything else is ok.

I replaced FP05. Now the bord flashes led DP23 and DP35 and keeps beeping. Also RP24 is smoking and getting black. Also I marked the three high power red cables that goes from the lamps to the HV but did not mark witch ones went on the HV. There are three of them. Does it matter wich one goes where? As well to make things worse, I broke the steel connector inside the HV whe pulling on the cable. can I remove it, or do I need to purchase a whole new HV (labled TH01).

I hope things go better.

I was able to remove the steel cap from the HV and clipped the cable and resoldered thew cap on. the Service document does not show wich red cable goes to the HV. This is only high power right? so does it matter wich one goes to one or the other?

thanks

I found my awnser on the delfection page 2 of 2. They are all connected in parallel to TH01, so it does not matter wich one goes where. Still need to find what short is causing RP24 to glow orange. it's a .47ohm so it need quite a bit of current to get this hot.

Making some progress, Isolated short into two lines on the deflection board 1/2 , B+ 115 V1 or B+ 115 V2. I will remove KG02 to try to isolate witch one tonight.
