Procedure to exit child lock with pin unknown / "locked" displayed on screen Cooling tech digital microscope software hangs my pc tv#Philips TV Model: 32PW6526-05 (SA10E Chassis) Replace CP007 and CP008 close to the U4614B (Found this tip posted under Thomson VPH6601 which seems to have the same PSU) Press Mute button on handset and any button on the TV, hold for a few seconds and menu will appear Just glue or replace the part (use loctite or super glue) This slips and doesnt grip the motor hence does not turn the drive gears. A plastic cap fits on the spindle of the motor. There is a plastic piece on the motor which rotates when you press play or eject. works occassionally then doesnt work at all Cooling tech digital microscope software hangs my pc code#Sound is okĬheck IC101 (BA7630F), if video signal comes to input (pin 1) but not present at output (pin 14) then replace this ICįault code F80. Most capacitors you will find are leaking electrolyte. Check all large electrolytics in the secondary (Ie bigger that 470uF), check all capacitors around IC950 (error amp.). dead, poor frame, poor E-WĬhange all electrolytic capacitors in the primary. output short circuit, replacment blows short againįirst check power area and repair dry joints then change all high voltage (PF value) capacitors in the horizontal section, this fixed the problem As there is evidence of scorching on the board the use of a more substantial component would be indicated perhaps with small heatsinkĭead with H. The surface mounted power transistor on the teletext module requires resoldering. Intermittent loss of syncronisation, both horizontal and vertical This value should be no less than 200ohms Remove horizontal transistor and measure the resistance across any two pins. No picture and sound, only a high pitch sound at switch on Check the +150 volt rail, 145V is too low Replace R3509 with a 47k 1 Watt version (483). There may be no 5V to the microprocessor. Philips TV Model: 25PT4423 (L6.2 Chassis) Also it is worth replacing Q580 anytime these sets come into the workshop with a BF422 Ideal/Slx TV Model: IDTV28T/IDTV28N/SLX28T2/28N (SM2 Chassis)ĮW fault then set went dead (tripping), R711 on EW panel burntĬheck for dry joints on C620 (0.47uF, 250V), if dry replace then check Q602 and R618 (5K6). Unit not working, no FL display, ticking from PSU, head drum twitchingĮlectrolytic cap in PSU primary dried up (47uF, 50v) Thankfully ZD405 (8V2) had expired (almost s/c) and removed the redĬheck and replace PR512 (which is located towards the front right hand side)Ĭheck / replace C531 (680uF, 25v), only slightly leaky, but a new one cured the fault I was hoping the nvm had become corrupt and turned the red drive down but it was fine (To enter service mode press and hold vol up and vol down on the front panel and switch set on). Jvc TV Model: C-V14EKS/B/W (Onwa Chassis) Resoldering both sides of it cured the fault Cooling tech digital microscope software hangs my pc crack#There was a very small crack in the solder at RH23, this is a 2K4 surface mounted resistor located at the back of the tube base. Very strong red content in the picture, sometimes the fault would clear with the strong red content fading until the correct greyscale was achievedĪfter much searching around i found the problem.
