I would certainly find a bad capacitor in the standby(deflection area). You are not getting the correct voltage to keep this set in standby. A bad capacitor will over correct the voltage,and create a high voltage shut down. I have not repaired this particular model. I would look for a 160 to 250 volt capacitor (sometimes two) at 1 Mf, 2.2, 3.3 or 4.7Mf. These will always go down. Please inspect check and replace these. Your TV may come back on. If it will not power up, chances you have a bad picture tube.A bad picture tube will also do as you describe (Rare,but can happen). Thanks for asking and show all hands of support!

Hello
This is a short circuit indication. There will be some kind of circuit short on the main board of this tV. Just check it. The most common fault I detected so far is with horizontal output section. Check that section for any faulty or leaky components. The work is a very skilled one, and you must have through knoledge in electronics, and all testing equipements and you must have the awareness to use these testin equipments. Eventhough the fault is a simple one, detecting the actual fault point is a very skilled job indeed. Check these I've stated above. If you want anymore assistance from me, feel free to get me by FixYa. OK.

    Many of these later model Toshibas were assembled by Orion electronics. Orion. Ilo and Durabrand and Sansui TVs have the same boards. There are many bad caps. Replace 35 @50 volt !Mfs caps.There are several of these. Replace the 35 volt 100 Mf in the vertical section. Thought you would like to know!

Similar problem here - pump was set for a 58 minute normal cycle, I look in and see it is now showing 67. Hmm. Attempt to shut it off because it is just sitting there pumping and pumping. Power shuts off but pump keeps running and add garment light flashing red. Cannot open door (to add garment or not) Unplug the unit and the door will not open. Anybody got a clue what's up? I have a wash in, service is closed due to a storm today. Just bugs me that it is 6 months old and seems to act up a fair bit electronically.

I put a tape in and it keeps flipping sides without playing and pops out and says Error. It even does it with a CD-Cassette Adapter. Before the Cln came up and I pressed on the eject button and that...


Cassette decks have sensors on the reels which tells the deck when the tape is at the end. When the reel stops the deck switches the direction of the tape and sometimes the position of the head(depending on the deck design). Most common problem is the tape is hard to turn, or the deck won't turn it ( deck thinks it's at the end, click, still won't turn, click, won't turn, click) you should fast forward and/or rewind your tapes from start to finish once in a while to keep them lined up(narrow spool/less friction), you shouldn't have to but it works. BUT,...your problem sounds like a slipping or broken belt/or dirt causing the problem. Take the deck out to have a look and clean the capstans(rubber rollers)belts,heads with alcohol and a Q-tip while your at it. Dirt's usually the main culprit and if you do have some other problem, cleaning it is always a win/win (It will also sound better clean)

Hi, I just purchased this used. It was working fine for one day, but now it won't turn on. Can u help? Haier CPN12XH9 12000 BTU Portable Air


If the water collection tank is full, it will not turn ON. Since you said the unit worked fine for one day and now it won't turn ON, more than likely, that's the problem. After draining the tank, the unit should reset itself and turn ON like it should.

The drain plug is on the rear of the unit, just above floor level. You can either drain it into a low sided pan or bowl that's capable of holding up yo a quart of water. O r roll the unit to a floor drain or outside to drain it. If you choose to drain it into a pan, turn the unit OFF & unplug it, before draining it.

I hope this helped you and thanks for choosing FixYa

I have a Haier model BC112G that stopped working. I unplugged it overnight and it still won't work. It just makes a clicking sound once in a while. Any Ideas? Wayne


Sounds like you compressor won't come on, check you warranty status before you call anyone. This repair can cost more than the unit did. The clicking noise is the overload on the compressor witch will happen if the relay fails (rare on this unit) or the compressor locked up. Either way, check warranty status on you unit before you call anyone, maybe cheaper to replace unit.... I hope this helped..

The unit worked fine when i last used it in the fall. I plugged it back in today and all the buttons lit up for about 1.5 seconds and then all the buttons went dark again. So I pushed the "on"...


I have had a problem like this in the past you can try taking the electric access panel usually on the side of the equipment. then look inside you will see a wiring harness inside and it literally takes nothing to bump it loose. This happens when people move these units they are pretty fragile and can be tempermental. Make sure the unit is unplugged while you adjust the wiring harness. If that deosnt work your display board is probably bad. Hope that helps

My Panasonic SC-HT995W keeps on flashing W and the rear speakers wont work. Ive tried turning off all other wireless devices but it still persists


I had exactly the same problem. My unit worked fine until a loose power cable resulted in the receiver being turned on and off a couple of times in quick succession and then after this the a/c in light on the rear speaker was lit but the wireless link light would not come on (and the 'W' on the main unit flashed constantly). The solution for me was basically a reboot. This is what I did;
- unplug the wireless receiver
- unplug the main unit
- remove the digital transceiver unit from its slot in the back of the main unit
- plug the main unit back in and turn it on - the 'W' won't flash as the transceiver has been removed (not sure if you if it's necessary but I made sure it was producing sound to the front speakers)
- unplug the main unit again
- reinsert the digital transceiver
- plug the main unit back in, turn it on and set it to produce output/sound (the 'W' will be flashing)
- then plug the wireless receiver back in again
...presto the link is made, the 'W' stops flashing and the rear speakers work again.

Hope this elaborate reboot works as well for you as it did for me.
