SOURCE: 42 LG plasma no picture but sound. found internal

Sounds like it started "Protection Mode" because of a failed electronic part inside the TV. When this happens, the TV will keep turning itself OFF or will not turn ON at all. This keeps the other parts inside from being damaged. Most likely the TV has a power supply related problem. The common part to go bad for flat panel screens circuit board that powers the screen itself. Most manufactures call it a Backlight Inverter Board.
But, I can't say what is 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptom.

You have a few choices:

1. Best thing to do, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, schematics, test points, and part# lists.Usually, cost under $20. Its the best repair guide material for fixing TVs. And most cases the new part cost less than $15 by searching on the internet with the part number.

2. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.


I hope I shed some light on the subject for you.

This is a common problem with these TVs. You can download the official Sanyo repair manual for this TV (DP42746) at http://www.eserviceinfo.com/downloadsm/43343/sanyo_dp42746.html. I uploaded it here when I had the same issue with my TV last year. The solution is almost always to replace the Power Board (Y-Main) and the Upper and Lower Y Buffers. The parts and costs (from Sanyo in July 2009) are listed below (NOTE: Sanyo will not ship these parts to anyone but a repair shop): 1. V4 Y-Main (Y-Sustain) Circuit Board (Part # LJ92-01200A, Alt Part # LJ41-02759A) - USD $139.00
2. Upper Y-Buffer Circuit Board (Part # LJ92-01202A, Alt Part # LJ41-02760) - USD $64.00
3. Lower Y-Buffer Circuit Board (Part # LJ92-01203A, Alt Part # LJ41-02761A) - USD $64.00
Sanyo charges USD $10.50 for shipping, which brings the total cost for parts to USD $277.50. From my research, a shop would probably charge between USD $500 and $700 to do this repair. FYI - there is a class action lawsuit pending against Sanyo for this issue. The V4 Y-Main (Y-Sustain) Circuit Boards fail VERY frequently in this TV due to overheating. Hope this helps.

I have a Samsung LN52A550P3FXZA. The TV does not come on.


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.
http://electro-medical.blogspot.com/
If blinks continue without any pause, the main board is faulty.

Technics amp sux520d won't turn on


Have you checked the internal fuse? If that has blown suspect an overload in the power amp stage, mostly caused by short circuit transistors or other devices.

Won't power on


Sounds like a Zenith or LG TV. It is most probably the Y board, when you hear the clicking sound is usually that. I am sharing this with you because it happened to me with a Zenith (POS). The red light (on my TV) is in the bottom right corner. In my case it was the Y Board. Best of luck

Won't turn on


Check the fuse in the plug. If that's ok then the fuse on the board might of gone. & if that's ok as well then the trancformer has gone bang.

Turn it on yesterday and i can hear a clicking noise for approx 5 secs then the standby light comes on and no picture. any advice, or reccomened repair


1st POSSIBILITY.....usually after 4 or 5 yrs EHT ( transformer that supplies voltage to tube ) becomes weak - then TV won't get ON.. means no picture no sound ( in some TVs ''garrrr'' like sound comes - that sound is from EHT.... but it is rare....some times ''click click'' sound comes...it is from relay switch ) ..... but LED blinks - in some TVs along with EHT 1 or 2 components like resistor, transistors, etc will also gets deffective ................ 2nd POSSIBILITY - main capacitor (very big in size) is blowing off...................... - so solution is TV circuit board has to be checked to find whether only EHT is deffective or other components are also deffective - price of EHT will be between Rs.250 (US$ 5) to Rs.600 ( US$ 12) & price of capacitor will be between Rs.50 ( US$ 1) to Rs.150 ( US$ 3) ..........iam from bangalore.....i have no idea about component's price & service charge in your area.....this problem cannot be solved by user unless user is a technical person having idea about components (resistors, transistors,diodes,...etc..), having multimeter , soldering iron & other tools...so my suggestion call TV service engineer or contact panasonic service centre

Technics a900 mk2 amplifier cut out sound to speakers.


First of all, Marcus, you will need to check if you have blown off the speakers. Just remove and use a good 1.5 AA cell to test both the speakers. If ok connect and switch on. try to hear if the relay is clicking or if you hear any noise. If not disconnect, open the set and use a multimeter to check if the output had failed. Check on the sections only if your are familiar working with circuits or else it might not be recommended. Get help from a friend to check the protect circuitt and the main board for failure of the mosfets/ outputdrives. If you can reset the amp do so by keeping the menu pressed on swithed on. or keep it off for anout 12 hours. it will reset on its own. I hope this helps. Good day

My Pioneer VSX-517 receiver will not power up. Have checked power cord & fuse.


good start. the next is to chech standby voltage 5 volt, that goes to the microprocessor which will enable you to turn-on the main relay(12 volt)that powers up the whole unit. so if you cannot hear a click when you push the power button the the standby transformer capacitor and the 5 volt needs to verified. if this is good the relay - 12 volt and if this is also good the micro is bad. oops-hope it doesnt come to that. the micro is located on the circuit board mounted on the faceplat-a large many pins IC.

Technics su-Z750 Intergrated Amplifier stays in Standby


HI...
This happens when one or more components in the power amplifier section has failed.

The protect circuit keeps large DC voltages off the speakers.

The only thing you can check for before finding a tech is that the speakers are firmly connected at both ends. If they are ok, you need a tech

PLease rate my help if this helps
