Olevia LT42HVi your guess is as good as mine

[Tvbob]

I recently acquired an olevia lt 42hvi
The set has a normal stand by light. When you press power button, light goes out. set comes on flashing a blue screen, no osd, key board doesn't function.
Have to remove ac power. Did a thorough check of power supply all stby and switched voltages are there. eBay has a new main unit for $150.00 I would like to find the "formatter" board. (all caps appear and check ok in circuit)
What is your educated guess? Know of another source for parts other than
shop jixxy and eBay. thank's guys

eBay has a new main unit for $150.00 I would like to find the "formatter" board.

For me personally, unless I really want to learn how to fix it for educational purposes, $150 is too much of a risk to spend on a part that *might* fix the problem.

New 42 inch TVs (plamsa or LCD) from name brand manufacturers like LG, Samsung, etc are selling for $500 CDN. Add taxes and it probably costs just under $600. With boxing day sales coming in about 60 days, I suspect 42 inch TVs will be in the $400 range.

With the right credit card, I can get double the warranty (1 year to 2 years).

Re: Olevia LT42HVi your guess is as good as mine

I have to agree with retiredcaps. News reports indicate a serious overstock of flat screen TVs, which will lead to significant price cuts in LCD TVs as the Christmas shopping season approaches. Expect 32" LCD TVs in the $200 - $250 range on Black Friday, possibly lower for the 'day after Christmas' sales.

If this were a case of replacing an obviously defective main board in a two year old name brand set with a certified good one, it might be justifiable. As it is, a lot of the boards listed on eBay as 'removed from set with broke screen' are no such thing.

Re: Olevia LT42HVi your guess is as good as mine

Fella's your are missing my point.
I have 6tv's in use, from a 50 inch plasma to a 8.5 lcd.
I fix these odd,hard to fix sets as a hobby.
This set was a high end tv in its day, Has a glass screen protector and a rear porch light (led's) for connecting cables, an atsc and ntsc tuners with split screen.
If service literature was available,I would troubleshoot it to component/board level
I know Olevia/ syntax have ceased operations (bankrupt) and are next to impossible to get parts for.
What I wanted to know was sources for parts for old sets other than shop jixxy and eBay. And one other thought. my 50 inch panasonic was a lightning total repaired with modules from eBay, Pulled from sets with broken screens.thanks again. bob

Re: Olevia LT42HVi your guess is as good as mine

Update..The Olevia 42 lcd is fixed thanks to a $150.00 main unit from. river valley elec .net
The module required no skill to change, Must of been designed (user serviceable) "so a cave man could do it" Has an excellent pix for a 4 to 5 yr old lcd

Re: Olevia LT42HVi your guess is as good as mine

Im sitting on an olevia right now thats junk.

it has blue LED on the front on, and standby 5v all around. but it wont turn on.

If i jump the power on signal on the power supply, a whole bunch of different LEDs across the main board light up indicating i guess power across the board? all power supplies are stable. but nothing. its braindead.

I had a toshiba 42" lcd with broken screen, for shits and giggles i plugged in the LVDS data cable from the toshiba boardset into the olevia panel, as the olevia panel wont fit in the toshiba becuase its too wide. but it actually drove the panel and worked.

but i dont feel like hacking 2 different brand TVs together, however since the olevia panel is still good, i just may....

Which part did you end up replacing? I have a unit someone gave me and it is doing the same thing only blue screen no control lights. You talked about a main unit which you have pictures main board.jpg of and the formater formatter board.jpg. I checked the river valley site and I am not seeing enything close to the main board.

They are all over ebay right now

Re: Olevia LT42HVi your guess is as good as mine

This is reasons I avoid generic TVs unless this is one of *very evident* bad caps PSUs.
I had 2 several years ago that was running "self-test" colors cycling through and I could not break out of this. Ended up parting them out for other stuff.

Cheers, Wizard

ummmn, did you just jump start that?
You could have broken the control circuitry if you didn't use a resistor as a jumper!!!!!!!!!!

Re: Olevia LT42HVi your guess is as good as mine

Na, i know what im doing. ive been doing this stuff for years man.

Anyway, i ended up making a sharp-o-levia

I had a chassis pull from a sharp with a broken panel. Then i had the olevia with the bad manboard.

Since the panel doesnt fit in the sharp, too tall. I wired the sharp chassis into the olevia T-con and panel, the inverters didnt match up either, so i used the original olevia inverters and just rewired the circuit to match the sharps power supply, and hooked up only the inverter power-on signal. didnt worry about the PWM signal or the protection signal, so the inverters ran full brightness, just tied PWM high 5V

Ran a test on the bench, it worked! the sharps electronics were driving the olevia panel. the chassis mount for the sharp actually matches the bolt patters on the olevia panel backplate, so i ended up bolting it right in, then hacking the back cover to match the new positions of the jacks.

Works :-)

mbates14, You are a "chip off the old block" or maybe I am the chip.
I repaired arcade games for 15yrs for a client, He never wanted to spend a lot of money.
There was a lot of rigging.

I know this thread is old, but if anyone is still paying attention I would appreciate the help. I have a lt42 hvi and have had it working fine for about seven years and now not so much. powers up but no blue screen and no ability to go to menu or options? any ideas would help.
