Please try to explain: Dead set?

Do you hear sound OR a buzzing noise from the power board?

Be aware support from Dell does not really exist--no schematics etc are available and I have seen several of these less than two years old where not one of the boards inside was available.

Are you aware of the puffed up capacitor symptom common in many of these sets?


Let me know as much as you can. I am here to help.

Kc LT-32x575. Turns on for 3-5 seconds with video then screen goes black but still have sound volume and channels change but no raster turn off and back on does the same every time


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.

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.

Unit wont turn on??? was charging unit overnight,now wont turn on tried holding all buttons for 15,30 seconds


It sounds like it's time for a new battery. Here is your battery:

If replacing the battery doesn't get this player up and running, you will need to contact Sandisk for repair or replacement of your player.

NO POWER ON INDICATOR LIGHT AND NO Screen Raster on Monitor


Hi,

Initially, pls check D854 on the Power Supply/Logic board. It is a dual diode. If you would prefer board replacement rather than component level repair, this might be of help. This of course would require a fair familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron. It would be to your added advantage access to a service manual or at the very least a schematic diagram with voltage readings. Should you be uncomfortable performing a DIY (do-it-yourself), perhaps your best bet would then be to seek the services of a qualified professional.

This is of course in addition to checking the usual, power cord, fuse, outlet etc.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.

26" flat screen akai tv


Hello RJ13,

This may be a problem in the HV section of your TV. My question is do you have raster, or is the screen totally black? If you have raster then this is a video problem, if the screen is totally black then it is a HV problem. In either case if you do not have a background in electronics I would suggest that you take your TV to a qualified TV technician. If you do have a background you will need the following items:

A schematic diagram of your TV set to know where the test points are and to see what voltages and or signals should be at what point in your TV set
A multimeter to measure AC voltages. DC voltages, and Resistance when needed.
An Oscilloscope to measure signals that should be present in various sections of the TV as shown by the schematic.
A signal generator to create the proper input signal for testing.

These are the major tools needed, not to mention a soldering iron, and a de-soldering tool

I hope this helps you,

Thank you,
