    IC chip voltage

    I have an old Cricket TF26 that dosen't work and has a LM3900 and a SN7400 IC. I know what the input voltage is supposed to be but is there a way to find out the pin voltage without a repair manual for the tester? Please be gental, I am new at this and trying to teach myself trouble shootng

  9. It was partially translated on 21Mar2009. Traduction. The television tries to start up 6 at 8 times and goes then to stand-by. The tensions in the secondary of the alimentation are correctly during the start up tries. In the chassis 11AK45B5 that JVC has taken in this model there is a the IC502, a small memory and this is the cause of the failure. By my dealer I found easely the programmated memory for €9. After replacing this memory the television was ready to return to the client. My dealer said this little memory is often the cause of the above described failure. Regards Maurice

  10. L'appareil démarre plusiuers fois de suite (6 à 8 fois) et se met en standby. Les tensions au secondaire de l'alimentation sont correct pendant les moments de démarrage. Dans le chassis 11AK45B5 qui est employer par JVC il y a le IC502, une petite mémoire qui est le responsable. Chez mon grossiste j'ai trouvé facilement la mémoire programmé à €9. Après remplaçement l'appareil fonctionne directement. Mon grossiste parle d'un élément qui tombe beaucoup en panne. Salutations Maurice

    check you tv regulator it can be breaking down uder the load replace it check also your horizontal output transistor,chek if there is a leak from emitter to base or ashor from base to collector

  19. A chassis Philips MG.1E had no green on the CRT. The Tension on the cathode of the green canon was only 50V. CRT faulty. Un chassis PhilipsMG.1E n'avait plus du vert dans l'image. La tension sur la cathode du canon vert était sulemeny 50V. CRT défectueux.

    Televion SBR 70WA6214/11 chassis Philips A8.0E bleu colour is going out after som time and image had bad quality (To much bringhtness) The tension on the blue canon on the CRT is rising to High 170V. Crt faulty In the same television the east/west correction was interrupting. Take the circuitry out of the mean board and remake the connections. La raison du disparition du bleu et de l'image mauvaise à cause de trop de luminosité est la tension trop haute sur la cathode bleu de la CRT. CRT en panne. La correction Est/Ouest était instable. Après avoir resorti le circiut imprimé de ce circiut

    go to http://www.chsinteractive.co.uk/electrical...-with-leads.htm and buy a new power supply, the new boards are more reliable that the old ones..

    You will not get 400v at the points indicated unless Q813 and Q814 are switching on. It has to be established whether they are off due to excessive load on the output side (test power supply off the set as already mentioned) and if still no joy, where on the drive side you are missing the required voltage. Much to test but much to gain. Regards and good luck (or look lol) Paul.

  27. I was giving the solution of a problem I found in the Vestel Chasis. It was the little memory IC 502 that was defect. I hope so to help people who have difficulties in this chassis. Salutions Maurice

    Changing the q813 and q814 didn't make any diverence; still no screen and after 5 minutes it goes in standby. Maybe it's getting time to get an other powerboard. Strange is that I'm messering 400V DC on the points below but not 400V DC on pin 3 and 5 of trafo 805
