Re: Sanyo DP46840 Shuts off after a few seconds
Side note. If i turn the volume down the set stays on. So it has something to do with the 13volt audio circuit. I would say its the IC everyone has problems with.Leave a comment:

Sanyo DP46840 Shuts off after a few seconds
Hello, Im trying to get a sanyo DP46840 up and going. It comes on for a few seconds and then goes into shut down mode. When this happens the audio will go out first then the backlighs will turn off and the whole set goes into shutdown.
I made a video showing the audio voltage dropping when this happens. I think it needs a new 13 volt IC chip.

Re: Samsung LN40a530p1f Dead
I removed it and any way i test it it says shorted and my meter beeps.
anything else i should check? mouser has them but before i order them im going to see if i can find a list of the common parts for tvs....Last edited by marlboroa; 06-29-2015, 04:58 PM.Leave a comment:

Samsung LN40a530p1f Dead
Im going through my "dead sets" and have a Samsung LN40a530p1f this one does not power up or have a standby light. It doesnt have any of the usual voltages.
I have came across QP801 Transistor Its a 5R199P It shows a dead short on all legs in diode test but its still in circuit. would that make much of a difference? -

So far everything i have measured on the hot side of power supply is 44 volts. the standby light does not come on and the set doesnt work.
its a sanyo dp58d33 -
Needed Service manual for Sanyo dp58d33
I have a sanyo dp58d33 that died in a lightning storm. (supposadly) anyone have a service manual for it? I havent taken it apart yet but it doesnt have a standby light so i expect something to be blown. -

Yep, anyone happen to have a schematic or where to start looking on the main board?Leave a comment:

Re: RCA 46LA45RQ no standby light or turning on
I know but i Cant figure out want needs to be checked on the back lights. From some video i watched it looks like this set has all the voltages on regardless if the set is on or off. Just not sure about the BK_ON. I also dont have any kind of standby led or power on led. The button does work though as i can measure voltage spikes when its pushed.Leave a comment:

Re: RCA 46LA45RQ no standby light or turning on
Heres some readings
Power supply
GND
5.22 ADJ
.06 BK_ON
4.78 PS ON
5.23 +5VSB
GND
GND
5.23 +5
5.23 +5
GND
GND
12.84 +12
12.84 +12
Then on the Main Board its 12.53 where it should be +24v...Leave a comment:

RCA 46LA45RQ no standby light or turning on
Hello, I have a rca 46LA45RQ that seems to not have power but it does have some on the power supply. Theres no standby light or backlight flash. I have tested the voltages on the power supply and they all test good. The 24 volt on the motherboard is at 12 volt not 24. other then that it all looks fine.... -

yea i just took those out right before the pic. I was going to take a pic of the backside but got distracted by the kids. The screws were in it for testing.Leave a comment:
