GE 46GW948 shuts off when cold then works fine

HI my GE built in July 2000 Model 46GW948 is havine a problem just started.
When first turned on after being off for a few hours it works alright and then the screens distorts(sometimes) and then goes black and no sound except maybe a little hiss or crackle, then comes back on,sometimes it actually powers off and must be turned back on. It may let you watch 5 minutes or 5 seconds or maybe even ten minutes at a time. It does this off and on for about hour or so and then works fine. Any help would be much appreciated

    Yes I can solder. This is my first repair on this type of equipment, I have solder many wires into connectors and on a board a few years ago, so I should be able to do this, a question I have is this how many convergence ICs should there be I only see one and don't want to disassemble any farther than necessary to avoid any problems that could cause. The one I see is on a single board with very easy access. Thank you

This is a classis symptom of poor solder connections that when heated connect well. If you can solder, you should be able to fix this yourself. Resolder any connections that appear to be grainy or have rings. Note: The most likely location of these poor connections are at the convergence ICs. These are large black ICs attached to a heatsink and should be marked STKxxx. There are high voltages floating around inside these sets even when unplugged, so be careful.

Keep me posted.

GE 46GW948 TV Sound turns up by itself. Checked button looks fine


What happened on a lot of these is the micro switches on the front go bad.

With back off (set unplugged) located the bundle of wires coming from front keyboard to top of set(a small pc board near the top of the middle of the three tubes).

Unplug the plug going to the keyboard----set will still work as remote receiver is also on that board.

Questions?

Mircowave runs but doesn't heat and it has a load hum.


You may need a new microwave..however, the diode may be defective or the magnatron tube may need replacing,,The magnatron tube is only warranted for 5 years so it may be used up as the model is (10years)fairly old.

GE Refrigerator-Freezer side works fine/Refrigerator side not ok


You most likely have a defrost problem. Check the inside back panel of the freezer. See if there is ice built up. If so, you have a problem with the defrost. 85% of the time, it's caused by a bad heater. It could be the termination thermostat, timer or fan. If the ice is built up. Take the panel out and defrost with hair dryer. If you want, you can now check the heater and termination thermostat. It's a closed switch that opens on the rise. If you fix it your self or not, To save your food. You can replace the panel and turn the fridge back on, it will operate correctly for 3 or 4 days. This will give you time to either get the part and fix it or for someone to get out and repair.
Please rate solution and make it worth the while to summit solutions. Thanks

Constantly runs but does not heat


The circuit board is faulty. It should be covered under the warranty. Call GE or the place of purchase.

I think that Thomson is the manufacturer or distributor for GE parts, and Global INC is one of their distributers. keep that it mind when looking for your screen. and you might be able to get it at vancebaldwin.com good luck
