Marantz NR1501 no sound at all.
Hi.
This receiver has no sound at all, also not on the headphones. In the service mode is said: check DSP. I have added 2 1000uf 16 volt caps one at ic 1006 and a other one parralel to C1204 on the DSP. I also found out the 5 volt was only 2,1. So I swapped the IC201 5 volt regulator. 5 volt is now ok.
I am looking for the update software cable and software itself. There is no DSP ROM value seen in the service mode. The field is empty. For those with an eye for detail: service mode values I found:
Firmware: 090921-1
DA: 9-2
DSP: (empty)
HDMI: 10042011...

Vestel 17MB62-1 V2 bad ceefax/teletext.
Plain and simple, the ceefax of this tv (It's an OK OLE221B DVD D4, but with this Vestel board inside) is malfunctioning. Lots of text is missing.
In the Netherlands we still watch teletext.
Is it a software problem? If yes, what is the right software to reload it?

Salora 24LED6215CDW delayed/no sound.
L.S.,
I have this tv which is made in the Lithuanian Tauras factory, which doesn't excist any more from what I heard.
The problems are:
-when the volume is low, a very short period of loud sound (a brief moment)
-no sound after a few hours
-The sound is not synchronious with the picture, but delayed.
The mainboard is a HK-TSP.9202P63.
The screen is a LK235D3HAOS.
This is a DVB-C/DVB-T tv with a build in DVD player.
What I did is to resolder some IC legs with hot air....the intermittent loud sound is...

32LC51 power supply: still not working after caps replacement.
Hi all,
this power supply starts with a red led, after hitting the on button it gives 4 green blinks, the last one lasts a little longer, and then swithes off. Back to red.
I replaced all the capacitors (exept the buffer elco's).
I resoldered all the power semiconductors and the transformers.
the board is a EAX32268501/9 rev 1.1
I know a EAX32268501/14 REV. 1.4 works also fine. I know that the tv will work with a good board, because I have 2 tv's of this type.
The replacement board is called EAY34795001.
Notes: I can see a red led turning...Last edited by Nikolai Tesla; 12-04-2017, 07:24 AM.

Re: Sharp LC-40LE810UN question
Dear guys, I have a Sharp LC40LE810 E with a DPS126CP board also. The both axial fuses are blown (3,15A). I cannot find a malfunctioning semi conductor till and up to now, even the Greatz rectifier measures ok with my Fluke multimeter. I understand there are problems with the opto couplers, and as I can imagine, it can damage a SOPS. What shall I do? Replace all 4 opto couplers, but one is different. PC701 is a cosmo 101817, but PC 7702, PC7703 and PC7901 are PC123's. Is this power supply willing to start up with a viariable transformer? (is this...

Re: Helop wanted on a Delta DPS-141CP-1-A power supply.
Semerchet wants to share his Delta PSU knowledge with me. I send him a PM.
PS I read on a German forum that we should also replace PC 7703, a PC123Y22FZ opto coupler.
SO the repair shopping list is:
PC 7703 PC123Y22FZ
D 7902 SBR20A200CTFP
Q7909 KIA378R12PI
Q7911 AP6679GI
Happy repairing!

Ja, ik heb de orginele transistroren bewaard. je kan me mailen op [email]altijdvoorwaarts@gmail.com[/email]Dag Semerchet,<br /> Dank voor je a...il.com[/email]

Help wanted on a Delta DPS-141CP-1-A power supply.
Hi guys,
I have a Sharp Le46E820. The complaint was tv works for 5 seconds.
On a Dutch forum I read the tip to replace Q7911, Q7902 and Q7909, in fact:
SBR20A200CTFP 1X
K1A378R12PI 1X
AP6679GI 1X
I started replacing them, but after that my tv worked much shorter, only a few seconds, if it worked. What I see is backlight behind the "buttons" on front of the tv and the "chevron" (one part of the Citroen logo, lets say an upward arrow) flashing.
What I hope for: a circuit description, a good schematic...Last edited by Nikolai Tesla; 06-01-2017, 02:28 PM.

Re: Salora 32LED8115CDW switches on and off.
Problem solved!
I asked the Salora agency in the Netherlands dor the firmware and bootloader. I think they send me the firmware (it had the name upgrade loader.pkg).
What I did:
1. put the software on an USB-stick
2. cooled the U10 and U12 flash roms till they looked white
2. press ok on the remote
3. put in the AC cable in the wall socket
4. stopped pressing ok when the led flashed quickly
5. The tv came up on 1, but...the software was updated.
The problem is over!...

Re: Salora 32LED8115CDW switches on and off.
It's true. With cold spray my tv stays on and will stay on. A single treatment does the job. I put also soms flux on the NVM chips and did a resolder/reflow attempt (In the oven 200°C/10 minutes) without success.Last edited by Nikolai Tesla; 05-28-2017, 10:19 AM.

Re: Salora 32LED8115CDW switches on and off.
I have good picture and sound...for 5 seconds. This morning the tv stayed on for some time...I hope someone can recognize the boot loader ans software I need or is it another problem? I will freeze my memory chips again later to see if that's the cause....Last edited by Nikolai Tesla; 05-28-2017, 06:34 AM.
