Sanyo TV will turn on but no picture and will not turn back off with remote or manually

no, but have the buttons in question tested with a remote tester, may have had a liquid spilled on the remote and two buttons next to each other are affected, if not the remote it is serious.

Might be. But, before making it sure, you have to confirm the condition of its back light inverter baord, and CCFL lamps.

Your set is still under a manufacturer warranty. Take your set back to Wal-Mart and they will send it out to be repaired, or give you a new one.

If the backlight of the LCD-panel does not function, (no picture) then Master and/or Slave inverter are defective. Inverter boards are screwed to both sides of the LCD display, if they have revision 1.2 boards then they will need replaced with revision 1.3 boards.

call to the tv service center and do the required things my dear..........
plz dont try to repair it without any experts becoz tv when switched off also contains many voltage in it...

First, you need to know the sub-model of your TV.

It is called "chassis" and is shown on the back of the TV on the label where the model number is shown.

For example it can be "P42849-00" or "P42849-01".

Then search at www.coppelltvrepair.com/search or just go to www.coppelltvrepair.com and enter the link for SANYO DP SERIES to search for that.

Here's an example of a repair service (note it may NOT be the one for your exact model though!):

Hope this helps!

Hi,
all you need is optical toslink to rca converter(adapter)
but you will really loss some clarity and features
because converting digital to analog always eats up quality
and the disadvantage is still now these adapters has 2.1 output not 5.1
i hope this will solve your problem
regards,
cseian

Even tho we change settings on Phillips flatscreen Model 50pfp5332, if we turn it off and back it' shows it's RETAIL SETTINGS. We do not have the original manual and would appreciate your help........
