Sanyo DP42849 wont power on.

[lleonard3]

Hello
Working on a sanyo dp42849 chassis p42849-04

When turning set on green power light comes on and the usual click sound
Unit does not power on. After about 30 seconds click sound green light
goes off and then back on and click but nothing happens. No backlight
or sound. Ive checked power board voltages 24,12,5 all available. I am
assuming the power failure circut is shutting unit off. I dont have manual
for the 04 chassis just the p42849. It appears to have some changes that
are not in manual. Any help will be appreciated.

Thanks
L Leonard

Re: Sanyo DP42849 wont power on.

Sanyo DP series, including DP42849 have two common sources of problems: the main board and the inverter boards.

FOr the record, we've serviced hundreds of main boards and sold quite a few inverter sets and I am yet to see a single failed power board.

Which does not say they never fail, of course. Just much more rarely..

The main board can fail in different ways and result in different failure symptoms.

I'd say wait a little longer to see if the TV remains on (front LED lit) or does it cycle every 30-40 seconds.

If it stays on and doesn't cycle then most likely the main board is OK and you're looking for new inverters.

If it shuts off (front LED off or red) or if it cycles every so often then it's probably the main board.

Note the DP42849 comes in several different releases, all different enough to each other to actually NOT be appropriate to refer them to as "DP42849".

You need to know the exact chassis model of your TV (e.g. P42849-00) and look for that to be certain you'll find the part your actually need.

Better yet, open the TV and look inside for actual part numbers...do NOT rely on what Internet is throwing at you because more often than not it will NOT be what you will need.
