Our apologies for the delay in posting new tips over the last few days, We are currently working on a MAJOR database update which will be available in a few days : -)Hitachi TV Model: C2. TN (Nokia Stereo Plus) Chassis). Very strong red content in the picture, sometimes the fault would clear with the strong red content fading until the correct greyscale was achieved.

After much searching around i found the problem. There was a very small crack in the solder at RH2. K4 surface mounted resistor located at the back of the tube base. Resoldering both sides of it cured the fault(Sparky). Jvc TV Model: C- V1. EKS/B/W (Onwa Chassis).

No Red. 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). Thankfully ZD4. 05 (8. V2) had expired (almost s/c) and removed the red(Andy Doswell). Sanyo Video Model: VHR7. E. Dead. Check and replace PR5. T. t. r. s. Also it is worth replacing Q5. BF4. 22(Leonard O'Brien).

Philips TV Model: 2. PT4. 42. 3 (L6. 2 Chassis).

Stuck in standby, LED on, no HTThere may be no 5. V to the microprocessor. Check R3. 50. 9 and D6.

Replace R3. 50. 9 with a 4. Watt version (4. 82. D6. 50. 1 is type BZX7. B5. V6 (4. 82. 2 1. Check the +1. 50 volt rail, 1. V is too low(Adel Ibrahim). Rca TV Model: F2.

CTC2. 03. AD5 Chassis). No picture and sound, only a high pitch sound at switch on. Remove horizontal transistor and measure the resistance across any two pins. This value should be no less than 2.

Roughtest). Sony TV Model: KV- M2. U (BE1 Chassis). Intermittent loss of syncronisation, both horizontal and vertical.

The surface mounted power transistor on the teletext module requires resoldering. As there is evidence of scorching on the board the use of a more substantial component would be indicated perhaps with small heatsink(Desmond Armstrong). Samsung TV Model: CZ- 2. D8. 3NS. Double picture or raster shifted.

Check R4. 14 (1. 5K)(Leonard). Sony TV Model: KV2. Dead with H. Check all large electrolytics in the secondary (Ie bigger that 4. F), check all capacitors around IC9.

Most capacitors you will find are leaking electrolyte. Might be a long job!!!(Andy Doswell).

With tv off, hold volume up button on tv, switch tv on and keep holding volume up button whilst pressing standby on remote (this must be done within 4 secs of switch on) at no time let volume go, press the yellow memory button on the handset to store(Steve Taylor).

Toshiba TV Model: 2. W2. 3B (1. 1AK3. 7 Chassis). Procedure to enter the service mode. Press the menu button then 4,7,2,5(Josh). Toshiba TV Model: 2. W2. 3B (1. 1AK3. 7 Chassis). Picture displaced vertically, picture too high or low.

This problem was cured by entering the service mode (menu then 4,7,2,5), then pressing the green fastext button to access geometry settings, selecting VP1 (vertical position) and adjusting as necessary(Josh). Sony TV (BE3. D Chassis). Procedure to enter the service mode.

Press standby, i, 5, vol+ and tv (TT should now be displayed on the screen indicating the set is in the service mode)(Josh). Grundig TV (CUC7. Chassis). Power supply blown. This is often caused by a dry joint at C6.

F, 3. 85v) for o/c, this item is not included in the ususal p. Josh). Sony TV Model: KV3. TS2. 0. Dead no click, Q5. Q6. 01, Q6. 02 shorted and blown fuse 6. Change all the above parts and also check R6. C5. 12, C5. 25, D6. D6. 08, D6. 09, D6.

D6. 22, VDR6. 01 off primary side of T6. I`ve also found T6. Tough. Dog, Sony has bulletin out on this model(Dwayne). Sony TV Model: KV3. TS2. 0. Dead, good tip that I always use to save changed parts after replacing Q5. Q6. 01, Q6. 02 and blown fuse 6. I hook up 1. 00 watt light bulb across fuse conection, then turn on tv, if light is very bright you still have a short.

You saved the parts you changed, light should be dim and or blinks(Dwayne). Sony TV Model: KV2. TS2. 0. Intermittent video or snow. Resolder points A, B, C, D in tuner PCB, check cold solder on tuner shield 2- 1.
