Is it possible to Flash Eprom....
hi
I got a sony CPD-E220 Monitor.You might know sony doesn't even care on crt monitors.My monitor does'nt work,when it boots it shuts down itself(tik sound heared) and the led changes to amber.so i took to a service center,they told the Eprom has been corrupted(even checked with in-built diagnosis,no display ).The tech guy quote me pretty high price which imo not worthy!.I decided to do some research and do it myself.this way work out much cheaper found the eprom chip M24C16BN6 found the software needed @ denom.com guys,i need some clarifications First of all,could this be eprom corruption or chip damage? It is possible and good idea to do this way?any complex work needed?(i got the eprom program in hex format and the chip) If possible,how to flash them?any specific method needed? How abt the error rate?if any prob occur for eg:bad flash will it spoil the monitor? Thanks in advance |

You need an Eprom programmer such as the one we offer at www.anatekcorp.com/testequipment/versaprog.htm John AnaTek Corporation The Electronic Repair Center at www.anatekcorp.com |

Keep in mind you'll still need a source for the software that goes on the eeprom. |

Weird, sounds more like a faul causing the PSU to shut down, either that or
it's not detecting (or recieving) the signal from the PC. I think EPROMS are the last place to look. That service shop might be trying to rip you off. Get a second opinion.

if ticking, the first circuit to check is horizontal deflection and
then power supply, but if you know nothing about repairs leave it to profesional engineer.... it can be little thing, but don't have to.... |
