Question about Philips CCC130AT 13 in. TV/VCR Combo

1 Answer

POWER TURNS ON FOR 30 SECONDS AND THEN TURNS OFF,

I CHECKED POWER SUPPLY READS OK CHECKED SAND BLOCK RESISTOR 3.18 SHOULD READ 3.3K ALSO READ VOLTS 41V ACROSS IT. I NEED TO KNOW WHERE THE IC OR HORIZONTAL OUTPUT IS. I TRIED TO LOCATE SERVICE MANUAL AND WASN'T ABLE TO GET ENOUGH INFO.

    I REPLACED 150UFD CAP 200V AT THE POWER SUPPLY AEREA AND ALSO TOUCH-UP COLD SOILDER. IT WORK LIKE IT SHOULD BE.

Are you a qualified technician or a handyman? I ask only because I feel a duty to tell you that it is important that you be honest with yourself as to your ability to fully understand the possible dangers in what you are attempting to fix. Are you using an isolation transformer? If not.........for your own safety do not continue!
A qualified technician would know where to locate the HOR output and your having the service manual may only add to the old adage that "having too little knowledge and attempting too much"  may portend further DANGER to you"

Ask a Techo for a $25 appraisal, that way you'lll learn if it is worth pursuing while remaining SAFE from possible harm.
That's cheap personal protection!

good luck with  one

Need a circuit diagram of a dewalt charger DE9108-xe 7.2V-18V one hour charger type 1:Q 96307-12/15 OUTPUT : 2.6A 7.2-18.0V 46.8VA


Can you (carefully!) measure the volts across them with a load (battery) and then the current through them by disconnecting one end, and if the charger is still working OK then they are V/I ohms, choose nearest value. 10k sounds very high, are you sure they aren't 1 ohm or less?

  • Optical Spull not move (up down).
  1. Check the flexible cable.
  2. Check the Optical spull.
  3. If you have SCPH - 3000 series, check the IC Driver (BA 5815).

  5. Check the optical flexible cable socket.
  • Optics spool laterally tilted or irregular jump when the engine turn on.
  1. Check the resistor on 102 block (In IC Servo Master Control area = CXD 3098 : 470-8pin,102-8pin).
  2. Check the resistor under IC Servo Master Control.
  3. If you have SCPH - 3000 series, check the IC Driver (BA 5815).
  4. If you have SCPH - 5000 series, check the IC Driver (LA 6508).
  • Optics can only read one CD/DVD format.
  1. Check the Optic Laser Diode.
  2. Check the Optic Laser Diode with Voltmeter : V3 (CD=1080 to 1260, & DVD=800 to 1300), V4 (CD=850 to 900, & DVD=1200 to 1400), V5 (CD=1200, & DVD=1400), V7 (CD=1200, & DVD=1100 to 1400), V9 (CD=1200 to 1400, & DVD=1200 to 1400).
  • Optics Lights not lit (Lens not light).
  1. Check the flexible cable.
  2. Check the optics spull.
  3. Check the SP 3727 IC.
  4. Check the Amp transistor ( in IC SP 3727 socket board), Upper for CD & under for DVD.
  5. Check the IC 7805 (IC Regulator).
  • Excellent optics but won't to read.
  1. Check the mecanic gear.
  2. If you have SCPH - 3000 series, check the IC Driver (BA 5815).
  3. If you have SCPH - 5000 series, check the IC Driver (LA 6508).
  4. Check the ModChip.
  5. Check the IC SP 3727.
  6. Check the resistor (in 220 block), between IC Servo Master Control & IC Interface (CXD 9611 BR).
  7. Check the transistor (in socket optics= pin 6).

I have a mitsubishi 60inch model # vs 60609. the green light comes on as you turn it on but no sound or picture any ideas on what could be wrong? please help


You will need to replace IC8c00 (STK 393-110) . This is your convergence IC. You will need to measure all of the 6.8 ohm resistors, replace as necessary. These resistors will have blue,gray and gold stripes, there may be sixteen of these. Expect to replace at least three of these if not more. Replace caps C8c05 (25 volts at 100Mf),C8c07 (25 volts at 100Mf). Other caps to replace are C2c86 (25 volt at 10Mf),C2V17 (25 volt at 10 MF) and C601 (350 volt at 1 Mf). you will also need a keen eye to resolder connections behind tuner TU1A02 (says RF). Jumper sockets CE,RG,DM,VU,DP,EL. Check and resolder socket connections KC,KB,AV1,AV2 and resolder IC 2p30. And you will also need to pull the power supply board, resolder jumper connections CE, RG, DM, VU, DP, and EL. Resolder the vertical IC , this IC will be of the LA78XX series,(do not use excess solder and short the pins). Resolder the horizontal transformer, and the flyback transformer. You will need a keen eye to visually inspect bad grounds on power resistors,horizontal transistor, horizontal output transistor any any and all regulator transistors located on heat sinks. This may seem complicated, time and patience will repair this. Spend an hour a day for two weeks to fix this. Thanks for asking and show all hands of support!

W/supply voltage fuse is ok w/output voltage no supply voltage on fly back


Very likely the flyback is bad. Most CRT sets have an SCR clamping circuit that "crowbars" or shunts power if the voltages on the flyback outputs are not within spec.

Power indicator open but no function audio,as well as selector my unit is an aiwa nsx k880 stereo


To start with you will have to check on the power supply for the fuses, the fusible resistors on the various sub power section near the main transformer. If OK proceed to see the recitifed DC , the supply to the main controller IC the microprocessor in the front panel. You will need some basic electronics to check for the +5 volt to the mP and confirrm if it is working. replace only if confident or get help. If this section is OK then proceed to the mode selector IC to the output IC. This may require some good technical support to prevent further damage by tampering so please check this out. Good day

Model AV-36950 won't turn on


Hi there, yes this is common. I dont know how much technical expirence you have, but be very careful there are many circuits that have high voltage on them, even when off, and these voltages can be lethal, especially any thing that is connected directly to the A.C. line [such as the primary of the power supply]. most of the rest of the set is isolated from the A.C. line. so be careful. now for the tecnical part, most common is a failure of the vertical circuit, the shorted IC will cause the set not to come on in order to protect the power supply. after you replace the IC and any resistors and diodes that may have failed as a result of the bad IC, change any caps related to the vertical circuit, they will be 100, 220, or 47 mfd @ 35 volts or so. lastly check the zener diode that is connected across the output of the IC for leakage or shorts. It is also possible for a filter cap. in one of the low voltage supplies to be open [it may be noticed as it will be pregnant.]to cause a no operation condition. so good luck and think safety.

No sound, no supply B+


Check for either an open resistor in the B+ line that feeds the audio amp IC or remove the IC and check for B+. If the IC is shorted, the B+ reading will read low.

Dvd player is completely dead.


First thing to check is the power cord with it unpluged. Do you get a resistance there or is it open?? If its no reading at all then the power transformer or fuse or current limiter resistor is open. If you do get a reading then you know your power transformer primary is good. Next measure the AC volts comming from the secondary of the transformer. AC volts? Good! Now Find pin 1 or the end pins on the microprocessor. 5 volts present?? No theres your problem get a schematic and troubleshoot the power supply. Yes 5 volts? Measure the display any volts on it?? Ok im sure by now your gonna say no to one of these and like I said get a schematic and conferm all the voltages are present in the power supply. Most common dead problem in dvd/cd players is the power supply ie transformer,regulator, ic, ect, ect. Good Luck
