| Marca | Modelo (Chassis) | Sintoma | Causa | Solução | Por: |
|---|---|---|---|---|---|
| Hitachi | C2558TN G8Q | This set would not switch automatically into A/V mode when a video or any other equipment was connected via the scart | The set could manually be placed into A/V from the tv's front end controls. The cure was to replace ZD301 ZTE251. I assumed it was a 2V but as i had none in stock i tried a 2.7V zener which worked perfectly. It's located near the scart socket | ||
| Hitachi | C32FW523NA A8 | No or very dull picture with osd and text just visible, A1 control makes little difference, looks like poor crt | 18v zener diode Z703 s/c located near lopt, it is part of the acl beam current limiter | ||
| Hitachi | C32FW523NA A8 | Procedure to enter service mode | Switch tv on then press menu then press vol up and vol down on the front of the set simultaneously and hold until menu appears | ||
| Hitachi | C2119E Issue9 | No sound control, procedure to exit factory preset mode | Hold 'VOL+ and 'VOL- buttons whilst switching on | ||
| Hitachi | C2546TN | Prodedure to remove `C46TN` from screen | Press the 2 VCR buttons together, the menu will appear, then switch to standby mode, turn appliance back on and prompt should have disappeared. When tv is turned on it will ask you to search for a channel, select this and then cancel | ||
| Hitachi | C2864TN | Psu in slow trip. 630mA fuse on E/W panel blown | Top E/W diode leaky D704 BY228 | ||
| Hitachi | C28WS10TN | Poor starting, some times comes on then cuts out with LED going out | Dry joints along centre heatsink where the three ICs are mounted, reflow solder on ICs and then check HT 160 Volts | ||
| Hitachi | C1709T | Dead H.T high and tripping | Replace ZD903 and R909 39K also check ZD901 2.7v for s/c | ||
| Hitachi | CPT1446R NP84CQ | H.T fluctuations, picture becomes half white and half black. H.T varies from about 80V to 110V | Replace ZD902. It's a 10V zener diode | ||
| Hitachi | C32WD2TN2 A7 | Volume goes to maximum when volume plus or minus selected | Replace R039 10k pull up resistor for micro switches, gone slightly low value | ||
| Hitachi | C2519T G8Q | This set was dead apart from a hissing sound from the speaker, no standby led | 5 volt regulator on front panel had 13 volt input but only 1 volt output, Replacement cured the fault | ||
| Hitachi | C2867TN | The set was going off intermittently | Resoldering all three pins on regulator IC952 cured the problem | ||
| Hitachi | C32W511TN A7 | Intermitently goes to standby | Check R959 as described by Mark C24W511TN and found no problem there, however I discovered that several connections in the area of R959 had fractured. They appear to be components near/attached to a heat sink. Re-soldering the joins did the trick | ||
| Hitachi | C2846TN | Intermittent partial collapse of picture vertically picture squashes down temporarily | See Field collapse tip - it will happen so anticipate it and correct at you leisure rather than have the TV fail completely in the middle of you favourite show | ||
| Hitachi | C2846TN / C2546TN | Field collapse horizontal white line on screen | R710 dry joints. Same as C2146TN & C2546TN problem solved with thanks to Mike G & Barty. Power off/unplug. Get to circuit board underside with aerial socket up-R710 is near top and right of centre-cluster of 4 joints best resoldered |
