Neon C3298DVB stuck in standby

Re: Neon C3298DVB stuck in standby

now you have the eeprom fitted press Source> 2580 then scroll to 'RESET ALL,that should do it,if it dosent then there is another problem

Check EEPROM is fitted right way around.

Hi tom..eeprom fitted right way..i fitted it from the dot on chip 2 pin 1 which had an arrow on board aswell..also drew a picture to defo make sure..ive unplugged all connection to main board fron psu aswell as testing them plugged in..its weird as all the voltages where present at 1st

Re: Neon C3298DVB stuck in standby

Ive ordered the chip & the service mode sequence is correct as they confirmed it..will update when fitted..thx

Hi guys..fitted the new eeprom & no joy still red stanby light..retested voltages on psu HDZ2054-3A & now all not present except 1 pin of 5v..the caps on psu are F-con & Teapo..ive no card reader at mo 2 take pictures so ive used a stock photo if any1 can point me in the right direction..thx
Is the 47uf 50v normally the start up cap?..theres 3 of those but i dont know which 1 is the start up cap.

Re: Neon C3298DVB stuck in standby

yes,i had and still have the same problem,i did take off the chip easy enough and re solderd back on,the trick is to use plenty of flux and a decent hot iron,though after i removed it,i realised the chip can be re-programmed on board with a special clip.

i have the ezp2010v.2.1 programmer and i had the firmware to put on it,but as tom said if it was eeprom then it be easy to do,but these chips are spi flash,and more than likely need a more expensive programmer,i tried but it didnt work.but that was on the original chip not a new chip.it may work with new chip.

my board if i remember is a cv1o6ls1 v2.1 and it is always the flash chip that goes.

id be inclined to get the pre-programmed chip and take a chance seeing as its a 32",mine is still stuck on my bench ,il get the chip as and when i come across one,im in no rush.

Re: Neon C3298DVB stuck in standby

Ive found 2 sites that suggest source 2580 but no joy..looks like a new chip & then programming so stuck with this 1 for a while
This programmer looks 2 do the job Item number: 110771573141 on ebay..
Multimeter i see you had the same chip at 1 point on another thread..did you ever get it sussed..thx

Re: Neon C3298DVB stuck in standby

Ive come across this site in the.. http://www.ohmsupplies.co.uk & was wondering if any of you guys have ordered from them before?..They have the chip in stock & pre-programmed with delivery at 16quid.

If alls good with this site how easy is it 2 remove the chip..can it be done with a soldering iron & desoldering braid..thx..also is there owt else i need 2 know or is it just replace the chip..thx

Rip off personally I'd just sell the TV on to someone else who has a programmer.

It's easy to remove with experience, but I wouldn't recommend trying the first time on a board that's hard to get hold of.

I have no idea where you could get that done, sorry.

Re: Neon C3298DVB stuck in standby

How much would i be looking at from a shop 2 do it?..ive 20quid in it so far

Re: Neon C3298DVB stuck in standby

If it's one of those, I can't program it, sorry. That's a flash chip - not an EEPROM.

Thx 4 link mucka..didnt think it be that simple 2 look on ebay..doh..sun stroke i think..im gonna google my head off & see if theres a sequence out there..maybe if i get in contact with cello they may provide but i doubt it..thx for help guys

Re: Neon C3298DVB stuck in standby

When you going 2 uni fella?..where will i get 1 of these chips from?..& could you program it 4 me..thx

Re: Neon C3298DVB stuck in standby

Thx fella thought 2secs was enough after doing a little research..im hoping maybe on the remote there is service menu to bring out of standby..the pioneer i bought was done that way but im having no joy finding the sequence

not sure on the service menu there can be lots of different codes and orders that have to be enterd.

im sure there is a service code but i dont know that one sorry,someone may pick up on this thread and chime in hopefully.

Re: Neon C3298DVB stuck in standby

I have a little board I made up for programming EEPROMs (uses a PICkit 2) - so if you need a programmed EEPROM (SMD or through hole), let me know. Multimeter, do mind sending me that .BIN; I could upload it?

Re: Neon C3298DVB stuck in standby

no,you done it right,on these eeproms there storage is very weak,any little power outage/surge will corrupt the eeprom,it will proberly be a case of re/writing the eeprom,you can get the blank 24c/25c winbond eeproms fairly easily,they normally have SIG written on there part number.

Re: Neon C3298DVB stuck in standby

Thx multimeter..located the 2 pins put small flat srewdriver on both & switched on at switch at the side waited 2secs & still same..is this a matter of trying longer or this cant be done..thx

and one thing,some watch screwdrivers have a black coating on them,make sure that you use one with a clean bare metal blade or it wont make the correct contact with pins 5/6

Re: Neon C3298DVB stuck in standby

on the eeprom chip you will see a hollow dot on it,count the pins around anti clockwise until you get to pins 5 and 6 (where the dot is thats pin 1)
