Hitachi 43UWX10B No Picture No Sound

The DP23 light on the deflection/power PWB is not coming on. The LED on the supply is on. All other LEDS on the pcb are lit. Any ideas on which component on the 5v stand bye I should be looking at first?

    Multi meterat home. Ive worked in a computer repair and done some board repair on monitor and boards. If I need to while Im on VAC this week I can go to the shop and use there scope and other tools.

    Thanks! Im just starting to look at the manual. Hopefully it will point me in the right direction. Ive done alot of resoldering on cold joints but that didn't help.So now I guess Im looking for a something blown or out of tolerance.

    Looks like Ill need to find a 43UWX10b service manual because the trouble shooting part doesn't match up.There a couple parts it tells me to look at that aren't there.

    Or I should say similar to your model but it should work, pages in the 50s may help the most

    Well it sounds like you will have this running in no time then, anyway if you need any further help or want us to clarify anything, please let me know, but having the service manual should help you out a lot, a user guide is nothing compared to the service manual,

    Good luck

    sorry I couldn't be more help but I can't find a free manual and don't have access to one, you should be able to get one for under $15 for one, just don't pay more than that but at least you will save money by doing it yourself, if you need any additional help, please let me know. Thank you

I have a Hitachi 57f59A and the power went out and came back on but the tv did not come back on. There is no power light or picture and when hit power it clicks


Dead Set. Power supply chirps. E947 on the 115V and E943 on the 28V line is open.
Cause: Check all the fuses on the deflection pwb. Found E943 open and had a shorted 28V line on the Signal PWB. Check IK01, IK02 also caps, CK17, CK18, CK19, CK20 for short.

No picture or sound


Remove the rear panel. With the TV on you should see a red LED near the center of the PCB. There should also be 5 green leds, 3 to the left a 2 behind. If there is no red leds, check the fuses. If there are no green leds or maybe 1 or 2, disconect PSD5. It's a connector on the left side of the power board that connects to the audio board. It's the 3rd on fro the back. It's labled. With that disconected, turn on the set and look for the green leds. If all 5 light, the power supply is OK and you have a problem beyond that. If they don't all light you have a bad power supply.

DP23 LED not lit on deflection board no picture on tv


Good Day, Gil;
Your problem is in deflection circuit (115+v) check these: FP05, DP15, Q777, QH01, TH01, T701, etc. BUT suspect C707 1k pfd, 2kv, and check all the pico fuses (brown) 2" to the right of cap. Good Luck, big IRISH.

It's not coming on probably because the safety sees a short and is sparing you smoke damage. Double check to make sure any solder didn't cross or drop to another set of solder joints on the bottom. You might be able to get a service manual from here that could tell you more about the lights -> https://www.manualsparadise.com/ShowProductsForModel.do?model=M22931911

Check the stand-by circuit to the main pcb for the keyboard control. If no voltage present, check the 5v regulator in the main supply. If you are not seeing the LED on your supply up, it's likely you do not have the 5v stand-by.
