content: Hello; yes, I contacted PEAK, and they offered to send it to me (expensive postage, to England). It is down, the previous owner had not discharged the capacitor. I replaced integrated circuits, but I think the microprocessor is dead. It is programmable (PIC16F873A). That's why I'm looking for the software. I have a TL866 to reprogram it, but without software, I can not do anything. If anyone has a solution.....

content: That's a common problem with current generation tools, the brains are in the microcontroller and most manufacturers are never going to give you the binaries to program the uC, because it would enable clones too easily. It's easy to understand why it is reasonable to never provide these files. Maybe you could encourage them to send you an already programmed uC, that entails no danger to them that doesn't already exist once they release their product.

content: You probably know that it is not possible to read back the firmware of such microcontroller and as JoeN said ask them nicely to send you the pre-programmed microcontroller only.

content: Many people do not want to understand that this method of repair is no longer valid .... replace the components on a printed circuit date from the last century ... The modern method is to replace the complete circuit board and, in the case of a device containing only one circuit board, the solution is to buy another device.I worked in technical support LG and PANASONIC for TV's LCD and PLASMA and I simply changed the circuit boards, I have never even used a soldering iron in these interventions.

content: Hello; my method to me is to replace the components out of order by their originals or equivalents, being in troubleshooting tv, I replace the card when the latter is not repairable, or too many components have grilled, or: when the failure is not localizable! For the LCR40, I ordered a support to put it on a TL866 programmer. I will see if the microprocessor is totally dead with the program, or if the program is recoverable; in this case, all that remains is to load the software into the new microprocessor ......

content: Quote from: lionelkjh on March 25, 2018, 03:48:44 pmOn a device that is relatively simple and has a small number of parts like the LCR40, I think this may be valid. Some parts you can test in circuit. Other parts, a little hot air, and test it out of the circuit. If you are a gearhead and on your own time, there is often pleasure in doing this anyway. On a huge TV that only costs $500 and has a few boards in it plus a panel that accounts for most of the cost, swap the board is probably valid.That being said, when you are down to the uC, you have a problem for sure.

content: Its his choice, personnally i would not lose time on this, if its not the input parts, bye bye in the bin, Atlas have surely protected the code in the chip ... buying an tl866 adapter etc ... is not worth it in the end.IF he wants to play at it and have the chance to restart it, go for it. If Atlas doesnt sent him an programmed cpu or the compiled code, he knows what to do.good luckI work in a pcb manufacturing plant, we try for 2 hours to debug a board, if not, we recover what we can (big parts, thru hole, heatsinks etc...) we destroy the board and trash it.

content: Good evening, as I suspected, it must be sent home for an exchange of microprocessor and reprogramming. They sell it not only programmed. So I will try with the support of TL866, and I will give you information .... Cdt

content: Good evening; I received my support, I mounted it on the TL866 programmer, and alas, it tells me that the outputs are short circuit, or that it is damaged (meaning respected, and several tests done): the program is So irrecuperable !! What a pity! I would like to see it working again .... Atlas does not provide a microprocessor or software! Someone could help me to have the software (copy of his LCR40, because there is a plug or it can be programmed with a box externally via a computer) ?? Thank you all for your help !!

content: dont want to be rude, but you seems to have lost lots of time, sure you want to repair and use it, you may have invested more than its worthif nobody have or had any lcr40 code dump to share you're out of luck ..

content: As stated by others we are not able to help you, only Atlas are and they won't. You can't read the program from the chip once it has been read protected. You're unfortunately screwed without sending it to them or getting them to send you a programmed PIC.

content: Hello; I have so far only paid a few euros for the attempt to repair, and not as much as the price of a new (100-140 euros), I recovered, because his former owner told me he did not light up anymore! I am in France and a shipment to them will not be without risk of breakage or loss of sending (I already had problems in shipments!): The recovery of the file is the only solution!
