Blank Screen! Need help

After a bit of help. I have a Pumpkin KLD unit with android 4.4.4 on it.

800x600

RK3066

Ram: 1GB

CPU: armv7 1.6GHz (x2)

MCU: MTCB-KLD2-V2.50

6 months old

The issue is That the blacklight is coming on, but the screen is just blank. Have tried resetting the unit, leaving it unplugged for a few days and checking the ribbon cables are seated correctly. Nothing has helped and I have re-seated the cables, but to no avail. I did connected a screen to the rear video outputs and put a dvd in, this gave a picture on the external screen.

The touch screen is working as I can press where the presets would be for the radio and the station will change. I can also, from memory load up poweramp and get it to play music. So the touch screen is working fine and I assume android is working fine.

No idea what has caused this as the screen hasn't been hit. I drove for 4 hours one night with it working perfect, then the next day the screen was just blank as soon as I turned it on.

Could it been the screen has broke, or could be something else? Any help appreciated!
[MTCB Android Head Units Q&A] srfairhurst:
Sadly these units are not ment to last i have had 2 in 3 months the first the screen got very hot and components on the motherboard blistered i was lucky the ebay seller accepted it back and sent me a new one a different model one with no physical buttons on i put new firmware on it and messed it up but managed to flash back to the stock firmware then after 4 days the touch screen stopped working The ebay seller starstore88 said it's a problem with this model yet they are still selling them they have refunded me so i now need a reliable model one that is going to last.
[MTCB Android Head Units Q&A] fpscod:
Does seem that way!

After quite a while of me sending 4-5 emails to them to get a reply, i've ordere a new screen, touch screen and circuit board for the unit. What circuit board is a bit of a unknown at the moment, it's either the motherboard, or the board with the gps card slot.. only time will tell!

Should sort my problems.

Video out

Hello to all guys, I have a head unit Klyde with Android 4.4 and 2 monitors in the rear headrests. The video output of the head unit transmits the signal only while running the DVD. I know that with Raspberry the video out can be transmitted to the rear headrests with mtcmovie from sdcard but do not know how.

A small question about internal storage of my HU RK3188 4.4 KK : is there a way to extend the internal App partition? (1GO actually)

Hui Fei KGL head unit. worked pretty well on jellybean 4.2.2, no real problems other than constant wifi disconnection. Driving along yesterday lost sound.

Tried the RESET, no fix. Power cycled, no fix. tried different sources, no output. access amplifier settings, check, no difference. Accesses factory settings level of all in AUDIO is 4 (any higher it gets static).

Removed head unit, inspected wiring, both hi level and low level. All good. Checked amplifier, all good- still no sound output.

Removed headunit, installed factory headunit. Everything works as normal with sound. re-installed the hui fei, again no sound. Everything else works as normal except for sound output.

Upgraded firmware and MCU. kitkat 4.4.4 and latest MCU, new software works great etc, but still no sound output.

Normally when I power cycle the unit I hit a small pop or crack from the speakers, since the audio stopped I get nothing.

Currently have unit on workbench, with small speaker attached to hi level front L + -, still no sound output, tried CD, DVD, BLUETOOTH, YOUTUBE, SD CARD, USB, MP4. absolutely no sound output.

Checked MUTE, is OFF!

At a loss, what should I be looking for? it is 5days out of warranty, has been very good unit until yesterday.

Thank you, Sorry I know my post is a little hard to read. Was late at night.

I only upgraded the MCU after the sound dropped out, thinking perhaps it would fix the issue. Still no luck, I have tried every other MCU available as well. Simply no audio output from either speaker output OR low level RCA output. Hoping now that the ebay seller gets back to me.

[MTCB Android Head Units Q&A] tmiller101:
Not unless you want to install a different rom. Malyska rom is a good one he also increased the partiton to 2gb.

If you root it you could use a program like link2sd to increase your storage capacity.

Also, Download a cache clearing program like iorbit's AMC (advanced mobile care) and run it everytime you run out of space. Sometimes it frees over 500gb for me.

Hi all.....

I've got a problem with my Rooted HU 4.4.4 KK HU (RK3188, 1024x600), on Xposed MTC module :

When i set the override switch mode, with a custom "music app" (DEEZER) and a custom "NAVI app" (Icoyote), the switch between the 2 mode make my HU "brick" on start logo.......i must reboot system.

If i set with only custom " MUSIC" (DEEZER), there's no issue......

Any idea how to fix it?

---------- Post added at 01:49 PM ---------- Previous post was at 01:44 PM ----------

If you download and install the lastest rom you will have fuse support which gives you access to all of the internal storage. Im on the new rom and i have about 7gb for internal storage for apps and whatever else.

Should I keep my MCU as is? I don't experience any problem with MCU, except that shuffle is not working properly on Music app
[MTCB Android Head Units Q&A] Tryden:
Depending on the android version, I think 4.4 and higher you can only do an backup with a rooted ROM.

You can try to root your unit without changing the ROM first.

The MCU you can leave as it is, you dont habe to change it.

Hey Tryden,

With a backup you can save everything.

Hi, all......

Another problem with my HU (4.4.4 KK 1026x600 RK3188)....

Since a month, i use a SCANtool OBDlikn LX for my TORQUE PRO app.....first time i paired the OBDLink, it paired in 5 sec and work fine.

Yesterday, i try to paired a new WBH BT5 dongle, with some connection issues......so i erase the OBDLink from the BT setting.

I must say that i set Xposed MTC to override OBD, to match the WBH BT5......well.....

Today, i try to plug my OBDLink, and it's impossible to paired with it. The dongle is seen, but never connect to HU.

I try:

- to reset OBDLink (witch easily connect to my NEXUS 7)

- to uninstall TORQUE

- to uninstall Xposed MTC

- to clear the BT files

- to set XposedMTC with the OBDLink string

Nothing to do.....it doesn't paired to my HU......

Is there a way to initialise the BT config, a file to delete, something to fix this F.....g BT issue.....?
[MTCB Android Head Units Q&A] agentdr8:
Does the name of your Scantool adapter appear as "OBDLink"? If so, you shouldn't need to override the BT name in XMTC. By default, the headunit/rom accepts and pairs with adapters that start with "OBD".
[MTCB Android Head Units Q&A] SKOLSC:
Hi dr8 and thank's to answer.....

I know that i don't need to, but i still try before writing here.......

The string name is : OBDLink LX

Just one thing : when i connect the OBDLink LX to my NEXUS 7 2013 (ANDROID 6.0) for the first time, it display a dialog windows with a 6 number PINKEY, witch is never the same.

I think it's a turning PINCODE. But the BT settings don't allow to enter a 6 number PINCODE (only 4).......

Do you think my issue could be linked with this PIN request......?

(Note that for the first connection between my HU and the OBDLink LX, i do nothing with the PIN, and let the 0000 in the BT settings)

Hope you could help me, to avoid a full reset of the HU....

Try monitoring logcat while pressing buttons and see if there's any information. You can do this via Terminal like so:

If nothing shows up when you press the assigned buttons, then either mtc-keys isn't working, or the Xposed Framework isn't working.

Can you say something about the Parrot BT and and "better radio IC"? Is the FM radio as good as the factory head unit's? Thanks!
[MTCB Android Head Units Q&A] Oberbergler:
The Parrot Bluetooth is much better. My girlfriend said that she hears me better how with the smartphone, and that without the external microphone who was also included. The radio reception from the first impression is also better, but I not tested it while I was driving longer (only 100 meters). But first I had a Erisin 9405A who had nearly no radio reception at my home.
[MTCB Android Head Units Q&A] peti007:
Sounds great! Do you have the Klyde DAB+ modul too?
[MTCB Android Head Units Q&A] Oberbergler:
Yes, but also only tested a little bit with the antenna in the car. In the car it not worked so good, but I have a radio antenna on my car roof, which allows to connect fm and dab. So I will test it when I have the adapter. From my experience with the Erisin and a RTL dongle I can already say that on the roof it will work much better. But it found already in the car about 70 radio programs. :)

MTCiPod update suggestions

Hello

I would like to support you on improving the ipod apk for the KLD RK3188 platform, I have one of these I let me tell you that this app is a lot limited. Issues that I would suggest to improve:

1- Won't read iPod where the amount of song is big, Max 4GB, above that the app never reads contents. I have 80GB 5th GEN ipod and I cannot use it. If the amount of song is to high it should read the content partially and then keep loading but not all at the same time because this may be why it block and never play song for this case.

2. Artist album image (cover) never shows

3. Ability to search songs, artist or album

4. Cannot browse in Ipod by Artists>Albums>songs

5. Category to play song by genere
