Hello!

That can be repaired, the vertical and the horizontal that regulate the voltage towards the projection maybe lessen or fulty. you can let the service man/service center repair this. these not much cost you, that is very cheap part and a minimum labor cost.

Defective LED back lights strips, or damaged EEPROM on main board. I will try a main board first, if you do nor have a TV LED strip tester.

Hi guys

if u buy new battery for around 35$... its creepy thing that it again sucks within
6 month
so follow these procedure that i really got good response

1)Buy the new battery from any other dealers (u can use Nokia (std) or LG, Micromax, Onida... etc)
having same specifications as 1050mAh Lion-POLYMER 3.7v and having equivalent Size that fit into the case.

2)Now open ur dead battery, remove the sticker slowly, u wil get the polythene bag carrying the charge sheets
.
3)Please note that dont not disturb this polythene bag... (cutting, drilling or pinning), else it starts burning.

4)U will see a circuit above the polyhthene bag having two poles (+ve n -ve) just cut the poles of bag from the circuit and keep the bag aside

5)Now do the same procedure with new batt and remove the polythene bag.. and soilder with
the dead battery circuit. (check the +ve n -ve by multimeter)

5)Re-assemble with insulation tape and recondition it perfectly.
now check poles bofore starting.

Note : i got good result from this and i m getting 18-19hrs standby and 11-15hrs usage. Do it on ur own risk...and i m not responsable for ny harm)

Vertical lines down the center only means that you have a loose connection on the Yoke. Re solder all the connection on the yoke and where the yoke connection meets the main board.

best regards

Bounce horizontally usually means up and down,which relates

to the vertical output IC. Solder IC301, IC401 pin connects==try

again.You can easily isolate "bounce" problems by lightly

tapping on the vertical IC heatsink....Let me know if you need

further assistance.....T.

 

PS. Though hard to find, a qualified tech could do that repair

in home for 300. to 400.00...

Elsewhere! Bad hyper board =bad caps on board need replacement = find a different tech who has heard of this repair or
have him research fixya / Toshiba/ 42H81 / hyper board ......T.

Probable PIP sister board.Moderate skill & some tools needed.Advise==get a senior tech near you.

you got somes capacitor bothering you, and nop, there are nothing you can do, but call a tech, the problem could be in the video card or in the power supply but is a tech job....good luck

this is caused by a bad convergence module, and there are probably some dried out electrolytic caps in the circuit as well. i have one in the shop right now that came in with the same problem. if you have it serviced, make sure they replace all of the convergence modules (there are usually 2, but sometimes 3 of them), because if one went bad the other(s) is likely to go out soon as well.
