Samsung le37m86bdx/xec (le37m86bd) goes negative after few minutes of working
Hello guys!
so there's Samsung le37m86bdx/xec which arrived with defect - switched off after a while. Solved that soldering the contacts which seemed to have micro crepes. Now it goes negative after few minutes of working
should i check t-con? resolder chip contacts or just change it? Thank you!...

LG 40UB800V takes long to turn on
as said, TV takes long to turn on when cold. warmer it gets - faster it switches on. Capacitors are checked, they are ok.
maybe it's a strange idea but could it be resistors that work normally only when they are warm? some of resistors checked show me more resistance (sometimes even twice) than should according to color codes. have never checked them, have no idea if it's a normal thing
thank you!
by the way, powerboard is EAX65942801(1.6)
thank you -

Re: Sharp LC32D44E-BK backlight issue
@budm they all appear pink, thats strange. all lamps are new, taken in china, but i think all spare parts are made there, so.. may be bad contact? may be the connectors got loose in years?Leave a comment:

Sharp LC32D44E-BK backlight issue
Hi guys!
i've changed lamps on Sharp LC32D44E-BK (as far as google says it's the main problem of this model) and made the error reset. The TV worked fine for some days and turned back to the same problem. at some moment the lamps turn pink and then shut off. i've opened the tv to see the state of lamps and they seem fine. The transformators seem fine as well, have +- the same resistance.
what could it be? bad contact with lams? should i solder them?.. i really like this TV, the image is much better than modern ones
Thank you! -

Samsung lt19b300 backlight issue
Hi guys!
i've received a monitor samsung lt19b300 recently with problem - it won't turn on. Changing 1 diode has solved the problem and it worked fine for 3 days. Then started to reboot himself, loosing backlight, not turning on with standby light flashing 2 times.
i've checked all the power components out of the board, they look fine. resolded all the pins just in case of micro crepes which i may not see. all the leds on the stripe are okay (!).
seems to be the main board?..
can be the led stripe defective while having all the leds okay?..
thanks in adv... -

LG 37LH7000 vertical lines, no image
Hi guys! I don't have a lot of experience so ask you to help
the TV has vertical lines, no image, sound ok. T-con is changed, no effect. Cables are cleaned, no effect. I've also checked all pins on t-con going from main to t-con. Voltages on main seem to be ok. Bad panel?..

Philips
My TV has a thin red horizontal line 1-2pixel large all over the screen. It can partially change color while the image goes on. I guess this is the matrix problem. Is there anything i can do about? i mean, if the line is vertical, i can try to resolder contacts of the flex. but horizontal?.. any help is appreciated
