Hi gsm_boy
I have a small problem with my pana GD52...
I cleaned it inside and after set it together,the volume of earphohe(not handsfree earph.) is so low.
First time I thing,that it is in pins connecting the earphone to boadr.I used the CH-box to test it. When I turned the earphone vol up (in Ch-box) it looks that it's allright,but when I tested it with sim card,with standart calling,vol is so low
At the end I was reflash GD52 with newest soft. and replace the pana. earphone with nokia earphone (the diameter of pana earph. and nokia earp. is the same) only I have had soldered two contacts there.. Now it's working good,but I feel,that it should be better...
My question is: Is there anyway solution to volume up panas. earphone using some soft. that can change this information in flash (in Ch-box U can change the mic amp. too)
OR Is there anybody who can sell me new original GD52 earphone???
Thanx for all replyes
Looker

Hi Looker,

U wrote that u've replaced it with Nokia Speacker and your problem was solved.

I think u don't need to replace it with original one.

Furthur if u need Original one I can provide it to u .

And for Software I don't think that any software can Upgrade Speaker Volume if your Speaker is faulty(Only way is to replace the Speaker).

Hi gsm_boy
thanx for reply.
I was solved my problem by changing original sp. with Nokia sp. it's not best,but for me it's ok.
I only wanted to know if the problem is in soft or in bad sp.
About Ch-box: I think,that if U can to vol. up sp.phone much more than in standart mode (calling,pressing arrow up) U can to change some vol. information,but it's so hard (it's take long time with experimening)

Now it's ok,but have second problem with soldered contact on Nok.sp.phone.
Panas. feld down on the floor and sp.phone not work... It's bad soldered contact on this sp. phone...
I will make batter job and it shold be oK.
So end of pana sp phone problem...

Today I had Alca 301 problem...I can't to pow.up,but when I repl. and get back battery,phone pow.up, but keyboard not work...
Problem was in triple button in the midle of the phone. Man who used this phone,had plastic cover with a hole for this multifunktion button and it's all the problem.
Problaby some watter come inside by this button and started oxided with board and some contacts. I mean the power but. (C) was always switched on and it's all problem..

Hi Bband,
I have similar problem with C10, when I have empty batt. (phone switch off) I can't to switch it on (with charger too).
I need to plug the batt on some pow.supply for a while (5min) and after then,I can to switch C10 on.
And when I should have a full batt with charger plugged in(charging looks to be ok), I should see a flashing last quarter of the battery symbol,but it only show batt symbol (full) without any flashing).
Thanx for all answers

Hi BBand Check the coil on k/pad side of MBU
I think it is connected in circuit with the transistor that is why the board measures short.The coil is normally physically damaged by incorrectly opening the housing.It is the big coil on the right edge of the board & is part of your ringing circuit.

Hi Looker. Check 2 small diodes marked "5" near your system connector,normally they go leaky or short.
