Question about Samsung HCN436W 43" Rear Projection Television
Hi, I have a SP43H3HTX/XAX Samsung projection tv, I changed stk´s an 3.9 ohm resistors, however the tv turns off suddenly. If I press on/off in the remote control a few seconds after it turns off then a click indicates pressing on button the tv turns on and if I wait like 10 seconds after tv goes off and then press on button in the remote tv does not come back to on mode. I will appreciate any help
I had a similar issue with my Samsung. It would just turn itself off. I found someone else out who overcame it, forget the site. My fix was as simple as taking off the access panel to the lamp in the back and putting it back in making sure teh bottom went in first. It seems tehre is a switch that detetcs the door open and turns the TV off. The switch apears to "move up" with heat? Anyways, my TV would turn off every few minutes for severla weeks and now it has not done it in 2 days.

IF YOU HAVE TO UNPLUG THE T.V. TO GET IT TO RESTART, IT IS PROBABLY HIGH VOLTAGE SHUT DOWN. IT CAN BE THE FLYBACK TRANSFORMER OR POSSIBLE BE A SHORTED CRT.
DOES THE SET HAVE HIGH USAGE ON IT ? WAS IT A FLOOR MODLE ? IS IT WATCHED MORE THAN 4-6 HOURS A DAY ? YOU CAN DROP THE CRT BOARDS AND SEE IF IT STAYS ON. OR REMOVE THE HIGH VOLTAGE (RED ) LEADS OUT OF THE HIGH VOLTAGE BLOCK. MAKE SHURE YOU DON'T REMOVE THE ONE GOING INTO THE BLOCK. ONLY GOING OUT. ALSO CHECK FOR COOLANT LEAK ON THE BOARD. IF THE STK'S ARE ON A SEPRATE BOARD YOU CAN UNPLUG THE CONVERGENCE BOARD AND SEE IF IT STAYS ON.
UNFORNATULY SAMSUNG IS NOT TAKING PHONE CALLS FOR TECH. SUPPORT. THE ONLY WAY TO CONTACT THEM IS BY FAX, AND IF YOUR LUCK THEY CALL YOU BACK IN THE NEXT 2-3 WEEKS....
