our tv set need to be serviced. Here are some tips:
1. Open main fuse. The fuse is clean but interrupted. You can try replacing it with one o the same value.
2. Fuse Blown or blackened. Short in the rectifier bridge or in the switching transistor. Out of the power supply: supply line rectifier (100/150V) shorted.

Big Screen RCA Tv Model #P60923BL or OM60923BL

bamones, it`s possible but not likely, remove AC cord from wall outlet, remove back from set and follow the AC cord where it goes into the set, fuse is right beside where the AC cord attatches to the board, if the glass is black you have a dead short in the power supply, if it`s open but not black then try replacing the fuse, amperage is marked on the silver metal end of the fuse, look for a number followed by the letter "A". Example;
5A 125V would be a five amp fuse rated at 125 volts, DO NOT replace with any other value, good luck, BMW Rider

Emerson CR202EM9 is just dead. Tried to reset like discribed in the troubleshooting with no help. Is there a fuse or something that could effect power?

Surely there is a fuse inside it. Its rating will differ according to your househlod voltage. If it is 220VAC, the fuse for a 20" TV will be of about 3.5Amps, and if it is 110VAC, the fuse will be about 6Amps. Before replaceing the fuse, you just check for any short circuit inside the power supply reguator section of your TV. Without any reason fuse won't get burned. Just keep this in mind and open your Tv, and check the entire regulator section with the help of a multimeter, set in Ohms range, for any short is there or not. If there shows any short, get it repaired first and put the new fuse, otherwise the fuse you are going to insert will also get burned. Check it with patience. If you wants furthermore assistance, get me through Fixya. OK.

Main power button and remote will not turn on tv. It is plugged in and has 110. Worked last night but would not come on today.

The most common failure for these sets to go totally dead is the degaussing thermistor shorts out thus causing the A.C. fuse to open. The part number for the thermistor is D4DDF1R50001 and the fuse is part number XBA2A00101F... You can do a Google search for these parts. One you get the parts and look at the board where the A.C. cord connects to, the fuse and thermistor are not too far from that point. Its an easy fix if you have any soldering skills. Please take a few moments to rate my answer. Thanks...

No power

Check horizontal output transister short. Check AC fuse open. If it is open check powersupply section any short circuit and check PTC.

Sony Tv Model KV2162 M9

The SONY 2162 is a Old Warhorse. It was manufactured nearly 20 years ago. If the set is dead, and if no one has tampered with it, it can be repaired. One problem I found often in the 2162is that it's mains ON OFF switch failed regularly. check that.If you have knowledge of Solid State Electronics, please carefully open the Back Cover and first check the fuses. If they are ok, then check the SMPS switching transistor. If it is short circuited, then replace. Also check the Horizontal Output Transistor at the same time.

Dead from cable surge from blown Time Warner splitter.

On that Sony the only glass fuse would be on the primary side where the A.C. cord enters the TV. If it's blown then you have a bad rectifier diode or some other shorted power supply component.
