22 is a error code for a short protect which is triggering shutdown . Try unplugging the crt circuit boards and seeing if the fuses still blow when you press power.

push and hold the clock button until the hrs flashes then use tuning button to change numbers or if your radio had 2 small pen tip buttons that read hrs & min pushing these with a pen tip will set the clock

Samsung TV, UN60EH6003FXZA, Black screen, has audio. Replaced t-con board and TV worked fine for 5 minutes, then black wave came across screen. Can replace main board, is the new t-con board ruined?


If the new T'Con too have damaged, surely its main power supply regulator board is faulty. Over voltage to T'Con board. Replace it and the T'Con board. Never switch on the set, without proper fittings to T'Con board. Its protective cover should be fitted before you switch On the set. It acts as a shield as well as a heat-sink to the IC at the T'Con. If you switch On without properly fitted, the IC will overheat within minutes and will be damaged. Keep this in mind next time.

Vizio TV has sound but no picture


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement.

I have a red verticle line on my tv


Hello; I am John at J D Electronics in Poland, Maine. I have an LG TV that was donated to me. It is a plasma model DU-42PX12X same as many other LG models. It had 1 inch wide red and green vertical bar on the right and a blue and yellow on the left. These bars appeared intermittently. pressing on the control board would make the bars go away. I have read many blogs on this problem and they all say to replace the control board located under that huge A / V input board ( held in by 4 screws on the large aluminum frame). The original part is # 6871QCH038A The replacement ends with a C instead of an A Aprox 90 to 135 dollars. This board is used on many different LG and Zenith models and is a HIGH failure rate part. I like to know WHY parts/boards fail and I found out why this board fails. There is a large square IC in middle of the board aprx 1 1/8 inch square. This type of IC is called BGA or Ball Grid Array. The solder connections cannot be seen , since they are under the IC . This IC was not properly soldered at the factory and that is why hundreds of these sets failed. I used my hot air soldering station on it's highest setting to heat up this IC . The IC must be directly heated from the top and some heat on the bottom of the PC Board. Liquid flux should applied to the 4 side edges of the IC prior to heating. The bars are now gone! To get to this board, remove all perimeter screws and all middle screws of the back cover. The A V board will hinge back to expose the control board if you unplug the cables to the side inputs and the one to the button board. The set will still run face down on a table with something to prop up the bottom screen so you can watch the bars. If the set was run for a long time with the bars, there will be some darkening where the bars have " burned" the screen. This is perminent, but usually acceptable. John

LG DR-4810 DVD Displays " PLEASE WAIT"


to open the tray during "please wait", remove casing then loosen front panel (clips either side and underneath). Power up to get "please wait", then press small microswitch in bottom right corner of the DVD player unit. Have you tried resetting the unit (turning on and holding the power button for at least 5-10 seconds)? Have you tried unplugging the unit for a longer period of time (24 hours)? get your firmware upgrade through here(sorry its in german, you might be able to get an english of it through the LG site) - http://www.lgupdate.de.ms/ two cd's- bootloader.iso , update.iso Good luck
