TV TOSHIBA	TV2056	Toshiba tv mod. tv2056m, which has the contrast without acting, leaving that opaque image without contrast (gray image)	It was the defective computer.		BF.COLATNO
TV SEMP TOSHIBA	2157 U17	On this television "tv semp toshiba 2157u17" I came across a problem in the "menu" of the device's functions, through the control I only have access to "function and clock" and the others, such as "image, audio, adjust" I have no access, nor Even going to the TV panel to access it, I can't do it.	Hotel mode determines the maximum volume the TV can reach, fixes the brightness, contrast and color settings and determines which channel it will always turn on. To access this mode, press the “mute” button on the control and observe the “sound off” indication on the screen. then press and hold the “mute” key and press the “ch-” key on the TV panel for 5 seconds until “hotel mode on” appears. To exit hotel mode, we do the same thing until “hotel mode off” appears.	I disabled hotel mode and thus gained access to all of the device's menu functions. resolved.	BF.COLATNO
TV TOSHIBA	TV2090	This device on the counter, wsound it has a blue screen. indicating absence of RF signal.	Eeprons from the 24cxx or 24wxx series can be used in any of them, as long as their recording capacity (xx) is respected, that is: equal or higher must always be used. exp: 24c02, 24c04, 24c08 24c16	Defect resolved, the problem was actually in the eprom (24c16w6). The TV started working normally again and the channels could be tuned.	BF.COLATNO
TV TOSHIBA	TV2084 U13	TV with 20v on the q430 collector wsound it should have 14v6 and 0v on the emitter wsound it should have 9v7, check all nearby components and nothing is ok	Cause, ca33 connected to pin 5 of q501, just replace it and that's it.		BF.COLATNO
TOSHIBA	1482 U9	When turned on, the image would appear and then it would start to show vertical lines and come back successively as if the TV had raw solder on the vertical part, but even resolving it didn't solve it. The same problem continued.	It was cold soldering on the q830 a transistor that is next to the selector it has a heat divider and this defect on the TV kills the vertical completely if it is bad or with cold soldering or even if tsound is voltage on its collector	It was just a matter of resolving it and it was a file	This email address is being protected from spambots.

TV SEMP TOSHIBA	TV2159	Vertical closing at the bottom and folding.	Ci does everything wrong	Replaced and resolved.	BF.COLATNO
TV SEMP TOSHIBA	TV 2091KV U-15	Star TV, when turned on, turns on the LED and then goes out, the power supply voltage is 0 V.	The cause of the defect was the vertical output ci. tip to discover this defect: with the TV turned off, discharge the power supply's input electrolytic capacitor (the big one that filters the input voltage, normally 170v) then place the tip of the voltmeter from +b general to ground, place the voltmeter on the voltage scale 250v, keep an eye on the voltmeter and turn on the TV. In this case, you will see that when you turn on the TV, the voltmeter will show a voltage of 113v and quickly drops to 0v, this means that the TV worked and then went into protection, normally It is the vertical exit or the flyback that makes the TV depart and go into protection.

TV SEMP TOSHIBA	2159NFS U-18	This TV with the sound popping up has audio and it has no quality as if it were a module connected without the remote, this TV is serious, I changed an output, the output is powered by 14v.	Removing the q 906 from the trc board the sound normalized spot blanking transition		BF.COLATNO
TV SEMP TOSHIBA	2084FAV U-11	Tv always 2084 fav does not come out of standby. this tv triggers the power supply but does not have high voltage, I found 9v on pin 31 and pin 32 1.8v on q402 c=40v b=0.3 and c=40v and +b is normal .	I went to check the horizontal output and to my surprise it showed that it was running only on the x10k scale, replacing it solved the problem.		BF.COLATNO
TV SEMP TOSHIBA	2999JMS	This TV wouldn't turn on after changing the regular one 3 times, a new one, cracked, I got a good one and put it in, but the tr q 840 is getting very hot, and it won't turn on, the stand by LED is on but it doesn't start	On the rg 840 transmitter it was 4.3 volts, following the line I arrived at q 841 and after the change the device turned on and worked perfectly.	Conclusion q 801 and q 841	BF.COLATNO
TV SEMP TOSHIBA	TV 2157 U-17	This television has a dark image, I checked: the abl voltage and are correct, I also checked the hz output transformer circuit (tsh) are also correct.	I replaced the "c902" capacitor with a new one and the image was good.		BF.COLATNO
TV SEMP TOSHIBA	1021E	It turns on but the frame is reduced and tsound are some colored lines at the bottom of the screen	Deflector defect		BF.COLATNO
TOSHIBA	2982	Weak video, like no contrast	L16 memory replacement		Master Eletronica
TV TOSHIBA	TV 1455M	This TV came with a closed vertical, and it continues because I already changed it: the electrols. from the sector and nothing, vertical ci, deflector coil, I checked the height trimpot ok	Tensões sem o ci: 1-0v 2-0v 3-41 4-0v 5-0v 6-41v 7-0,1v	Resolved c303 2.2mf 50v with signs of leakage connected to pin 13 of ci502.	BF.COLATNO
TV TOSHIBA	TV 2098LMS U-16	This TV has a dark screen, the image appears but very dark, the characters are almost black when measuring the voltages of the filament 5volts screen voltage 250volts RGB 187volts already check the RGB capacitor and the screen capacitor are ok	I turned on the TV without the screen capacitor and it worked normally.	Replaced the scrin 2n2/2k capacitor and solved it.	BF.COLATNO
SEMP TOSHIBA	TV2050MAV U17	When you turn on normal brightness, it soon becomes dark with a weak image.	Broken track between r227 and d302	Fix the fault	Elias2305
SEMP TOSHIBA	TV2050MAV U17	When you turn on normal brightness, it soon becomes dark with a weak image.	Broken trail between r227 and 302	Fix the fault	Elias2305
TV TOSHIBA	TV2076	The TV comes with the keyboard and control functions locked	Tip: change the eprom and the capacitors polarized to the eprom.	Resolved: memory replaced.	BF.COLATINO
TV SEMP TOSHIBA	2157 U17R	This TV arrived with bu2508dx horizontal output,	After checking the power supply and peripherals and not finding anything abnormal, I put another bu2508dx on. The TV works normally without any heating, but if I turn off the TV using the remote, a very thin whistle starts and in a few seconds the horizontal output catches fire to the point of burning.	Solved after placing transistor d2624 horizontally.thanks	BF.COLATINO
TV TOSHIBA	2066MU	Once again; tv toshiba2066mu. this time with weak video signal. well; I started by checking that the control processor was normal because the characters in the contrast function worked normally, increasing and decreasing the dashes content.	But the video signal remained the same, very weak	When measuring the voltage on pin 30 of IC 601 TA8718N I saw that it was wrong. Following the alignment of this pin (the trail), I found R210 open at 20K. I just replaced it and the video returned to normal and the contrast returned.	BF.COLATINO
