| SEMP | TV2134 | Turns on and off quickly, with the yoke coil off it doesn't go off, but it makes a strange noise | 47uf/160v secondary power supply c634 | Barter it | Marcondes Lima, Ohm Eletronica-Jaicós-PI |
| SEMP | TV2934[B]SL SK-91 | LED won't turn on, blinks and goes off | C634 100ufx200v estufado subist. por 150uf x350v c635 330ufx50v estufado subist. por 470ufx63v | Substitute c634 c635 | toninho da eletronica |
| SEMP TOSHIBA | TV2134 SKY | When it heats up the vertical changes at the bottom.... | Ci do vertical | ELETRONICA INFOAÇU | |
| SEMP | TV1482 | Vertical partially closed | C 301 2.2 50 near ci oscillator | edezio eletronica | |
| SEMP TOSHIBA | TV2134 SKY | Sometimes it turns on and off and on | Q-606 | ELETRONICA INFOAÇU | |
| SEMP | TV2134 SKY | Image distorted and slightly reduced on the sides | Cap. c-311 47/160v | ELETRONICA INFOAÇU | |
| SEMP TOSHIBA | TV-2934SKY | Does not turn on, then hissing at the power supply, then yellowish image. | The TV did not turn on nor did the stand by LED light up, the ci601 strw6556a voltages were all at 0 volts with the exception of pin 1 which was at 174 volts. checking the circuit I found r603 68k was open, this resistor feeds the ci601, so I replaced it and the ci601 started working again, however the LED kept oscillating, increasing and decreasing its brightness and at the same time a hissing coming close to the traffic, the image it was normal, I then replaced c311 47uf/200volts (133volt filter capacitor that feeds the horizontal) then the LED stopped oscillating and the hissing also stopped, then I left the TV to test, after a few minutes on the screen turned yellow (image appeared normal but yellow predominated in the scenes). I refitted the solders on the tube plate and also on the ci201 wsound the video signal comes from, but without success, I gave the pins of the tube wsound the socket fits into it a good clean, as they had a darkened tone, when cleaning with a I fitted the socket into the tube with water sandpaper and the image was perfect. | This email address is being protected from spambots.

| SEMP | TV1492LAV U16 | Burning horizontal outlet | Capacitor change = c414 | joãotc | |
| SEMP | TV1492LAV U16 | Insufficient vertical | I saw in the tips found on the internet that it would be the q430, I didn't even test the old one, I put a new one straight in, but the TV didn't turn on anymore with the new part. | I decided to test the old q430 and it was shorted, I found the d431 (zener 10v) shorted too, I put the new q430 in and replaced the d431 and it worked normally, even the vertical one opened | Ailson |
