old technology, dump it. My work place at the airport just installed a 72" Samsung Ultra High Definition 4K flat television. Easily worth the $6,000 it cost.

Likely not related but HDMI does not like being connected if either unit is plugged in or powered up.

As to the TV let me know the brand and model number and what if any lights at all come on when you plug it in etc.

You possibly have a lamp issue but most of the cases like that,,

The capacitor is leak or bulged on top..You have to replace it to fix the problem

Hi lc99527,
This is an indication of faulty ballast board and or its power supply(gone to out-of-regulation) and once sense by the feedback circuitry it will automatically shuts off the power supply. First check for bad solder joints (crack/cold/dry joints) in that section. This is hard to spot, I would advice you use table/portable lamp or work in the brightest area to locate it. Once found, resolder it. Also check for leaky/dried electrolytic capacitor. Sometimes it has a bulged at the top but not all, you must have a capacitor checker to determine its condition. Shorted driver transistor in the ballast board will do the same symptom as well as faulty ballast transformer.
Isolating the symptom is technical and if you don't have necessary tools and test instrument and can't do the job yourself, I would advice you to look for a qualified technician to troubleshoot the problem.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Hello; If you did not completely reassemble the back cover(s) it will not likely work. Most sets have a safety switch built into all back panels and doors to stop the set from coming on. John

I just had the same problem. Came down to a bad cap on the main power supply board C871. This is the first filter cap after the diode on the 6V supply. Funny,, the schematic calls for a 25V part,, however this one was rated at 16V :-)

Replaced with a new one,,, all is good to go!

you need to check for bad connections at the bottom of the boards, may need to be resolder to correct this issue

sounds like a scaler malfunction.. but could be something else.
this tv is know for having bad capacitors.. check my tutorial on caps, they can give many symptoms and quite possibly are bad. if not, then you need a digital main board, or main board.

The service manual is available from www.partstore.com
It is part number Part# 3828VD0222B for $2.95
Hopefully the entire DM Module would not need replacing. Hopefully just capacitors in the DM module need replacing and if that is the case part store has these in stock. Their phone number is 866-925-7278
